DataDirect Networks and Cray to Deploy Leadership-Class Storage Solutions for Strategic Supercomputing Projects

CHATSWORTH, CA, Jun 04 (MARKET WIRE) —
DataDirect Networks (DDN), Inc., the data infrastructure provider for the
most extreme, content-intensive environments in the world, today
announced it has extended its alliance with Cray Inc., the supercomputer
company, to feature the next-generation Storage Fusion Architecture from
DataDirect Networks as a core component of its open-platform file storage
strategy. The SFA10000 is the first of the next-generation DDN
intelligent storage systems to be used in all of Cray’s high-end
supercomputers, which now includes the new Cray XE6 supercomputer. To
highlight the success of the DDN-Cray alliance, DDN is also announcing
the selection of the SFA10000 for two marquee Cray supercomputing
projects.

Next-Generation Petascale Climate Modeling System

To advance the state of computational climate modeling and research and
to improve global weather forecasting capabilities, Cray has been
selected by the National Oceanic and Atmospheric Administration (NOAA) to
deliver a petascale HPC resource, called the NOAA Climate Modeling and
Research System (CMRS). To support this leadership-class project, Cray
has selected the DDN SFA10000 system storing more than 4.5 petabytes of
data in a single Lustre file system. NOAA plans to extend this new Cray
XE6 system over time to achieve over a petaflop of theoretical system
performance, and it represents the fourth petascale system for which DDN
technology has been selected.

Multi-Site Capabilities Refresh for the U.S. Department of Defense

DDN has also aligned with Cray to greatly increase computational
simulation capability for the U.S. Department of Defense (DoD) High
Performance Computing Modernization Program (HPCMO). DDN will provide the
HPCMO with SFA10000 systems that provide a combined capacity of 7.3 PB of
raw storage to serve as the high-performance foundation for several
Lustre File Systems. The resources will be distributed across three HPCMO
resource centers to support the U.S. Air Force Research Laboratory (AFRL)
located at the Wright-Patterson Air Force Base in Ohio; the Arctic Region
Supercomputing Center (ARSC) in Fairbanks, Alaska; and the U.S. Army
Engineer Research and Development Center (ERDC) in Vicksburg,
Mississippi.

The award for the DoD MSRC refresh continues a long history that DDN has
enjoyed with the DoD HPC Modernization Program. With a combined total of
more than 400GB/s of aggregate peak SFA10000 bandwidth to be delivered,
the DoD HPCMO will realize a substantially increased I/O capability to
support the Cray XE6 systems they will support.

“Cray and DDN have always shared a unique, and mutual focus on the
requirements of advanced computation,” said Barry Bolding, Cray’s vice
president of scalable systems. “Cray, more than any other company, can
appreciate the unwavering focus DDN has placed on enabling open-platform,
scalable I/O for the world’s most complex HPC environments. We are
thrilled to reaffirm our close alliance with DDN to advance the
state-of-the-art and deliver better resources to the computational
scientist.”

The DDN SFA 10000, designed from the ground up to address the evolving
data storage requirements of multi-core, scalable computation, delivers
industry-leading capability of up to 12 GB/sec of read and write
performance and over 1 million IOPS to handle any workload. With 60GB/s
of fully-balanced, non-blocking internal bandwidth and the ability to
manage up to 1,200 storage devices (HDD/SSD), the SFA10000 is three times
more scalable than competing systems and optimized for online and
nearline storage environments. HPC-optimized features include native
parallel file system and application hosting, an active/active redundant
design, high-speed mirrored cache, intelligent performance optimization,
SATAssure data protection, fully-RAIDed drive enclosures and 8GB Fibre
Channel and 40GB InfiniBand host-port options.

As recognition of this truly innovative design, HPCwire recently awarded
DataDirect Networks with the 2009 Editor’s Choice Award for the Best HPC
Storage Product.

“For a company focused on the pinnacle of HPC storage performance, there
is no better validation of your technology than to be selected for use
with leadership-class Cray systems,” said John Josephakis, Vice President
of High Performance Computing Sales, DDN. “The challenges of scalable HPC
storage can be overlooked by other companies who capture the bulk of
their business from the general purpose storage marketplace. This award
is a validation of DDN’s “HPC-Purpose” focus and will serve as a
reference architecture for computational scientists who are working every
day to ensure our safety and advance scientific understanding of complex
phenomena.”

Scenarios: 2010 hurricanes may wreak havoc on oil spill, Haiti

(Reuters) – The Carib Indian god of evil, Hurican, gave its name to the word “hurricane,” and the 2010 hurricane season that started on Tuesday is shaping up to be a monster of potential malignancy.

U.S. | Green Business | Hot Stocks | Gulf Oil Spill

Hurricanes are feared every year because of the whirling destruction they inflict on human life, property, crops and industry from the Caribbean to the U.S. southeast Atlantic coast and the Gulf of Mexico. The annual hurricane season begins on June 1 and runs through November 30.

But this year experts fear destructive storms could unleash additional havoc on two of the biggest disasters — one natural, the other man-made — ever experienced in the Western hemisphere in recent years, the January 12 Haitian earthquake and the six-week-old BP oil spill in the Gulf of Mexico.

“HELL OF A YEAR”

The risk of hurricanes complicating the catastrophic situations already caused by these two disasters is increased because U.S. forecasters are predicting an extreme hurricane season with an above average number of powerful storms.

“This looks like a hell of a year,” says hurricane forecast pioneer William Gray, who founded Colorado State University’s respected storm research team.

The National Oceanic and Atmospheric Administration has predicted one of the more active seasons on record, forecasting 14 to 23 named storms, with eight to 14 developing into hurricanes, nearly matching 2005′s record of 15. Three to seven of those could be major Category 3 or above hurricanes, with winds of more than 110 miles per hour (177 km per hour).

The Gulf Coast may see a repeat of the 2005 season when a record 28 storms formed, which killed nearly 4,000 people and caused an estimated $130 billion in total damages. The list included Hurricane Katrina, which devastated New Orleans.

HURRICANE + OIL SPILL = “HORRIBLE MESS”

Some Gulf Coast officials are already equating the environmental and economic impact of the out-of-control oil spill to a Category 5 hurricane — with lasting effects on businesses, individual livelihoods and natural habitats.

But a hurricane churning through the oil spill zone would disrupt slick cleanup operations and ongoing attempts to control the leaking undersea well — including one currently seeking to place a containment cap over the leak in a bid to capture most of the escaping oil and pump it to a surface vessel. Other ships and surface platforms are drilling a relief well expected to be completed only in August.

“Obviously, the new concern we have is that we are entering hurricane season,” top White House energy adviser Carol Browner told CNN. She said spill response vessels might have to stop working in a hurricane, which would further delay the efforts.

Even more horrendous, forecasters warn, are the prospects of a storm surge — an abnormal rise in sea level created by a hurricane — whipping spilled oil and used chemical dispersants much further ashore onto beaches, vegetation and even homes.

“The foul mix would ride inland on top of the surge, potentially fouling residential areas and hundreds of square miles (kilometers) of sensitive ecosystems with the toxic stew,” Jeff Masters of Weather Underground wrote in a recent blog. But he added a hurricane could dilute the mix with sea water, and wash much of it off the vegetation with rain.

Nonetheless, the thought of a hurricane blasting sticky oil inland is high in the minds of many Gulf Coast residents.

“Even a small, small storm would dump the Gulf into our area which would be more oil than water probably,” said Ann Griffice, a resident of Empire, Louisiana.

Frank Gill, president of the National Audubon Society, sees a risk of a storm-driven surge crashing into the Gulf Coast, “leaving millions of nesting birds vulnerable to oil washing onto breeding islands, beaches, sand flats and mudflats, and seeping into wetlands, and coastal terrestrial habitats.”

HAITI HOMELESS IN HARM’S WAY

In disaster-prone Haiti, nearly five months after a catastrophic earthquake that killed some 300,000 people — according to government estimates — more than 1.5 million quake survivors are still living in over 1,000 fragile, crowded tent camps in and around the wrecked capital Port-au-Prince.

Relief workers are bracing for the extra-active hurricane season and hoping against hope that it does not unleash the kind of flooding and landslides which have killed thousands of Haitians in the past — even without the kind of vulnerable situation that the poor Caribbean country now finds itself in.

“This is a prospect that we’re certainly not happy about … We don’t want to have a secondary disaster on our hands,” Julie Schindall, international media officer of Oxfam, said.

An evaluation of 28 camp sites where Oxfam works has concluded that thousands of survivors are vulnerable to landslides and flooding due to hurricanes, the organization said. It called on the Haitian government to urgently implement a public communications campaign to inform people about risks.

Extreme overcrowding, little natural drainage and weak land structure were major problems highlighted in the Oxfam survey. Relief groups were working to improve drainage and help the communities to place sandbags around their shelters.

“When you see someone living under a plastic sheet, on a dirt floor, imagine that under a foot of water, Schindall told Reuters, saying there were concerns too that water pooling in the camps would increase the risk of epidemics.

The government and its aid partners have moved some survivors to more secure sites and are clearing storm drains.

U.S. relief and development group Food for the Poor said housing remained one of the biggest needs. “It takes only a few inches of rain to put lives in danger because that’s all that is needed to produce flooding and mudslides,” it said.

In 2004, Hurricane Jeanne killed over 3,000 Haitians. In 2008, hurricanes Gustav, Hanna and Ike killed some 1,000, destroyed 20,000 homes and wiped out 70 percent of crops.

First system forms before Atlantic hurricane season

The U.S. National Hurricane Centre started tracking the first low pressure system of the 2010 Atlantic hurricane season late Sunday, reminding energy and commodities traders of the coming storm season, which officially starts June 1 and ends Nov. 30.

The non-tropical low, located about 475 miles (764 km) southwest of Bermuda, was producing a large area of disorganized showers and thunderstorms over the southwestern Atlantic Ocean on Monday morning.

The NHC said the system has a medium chance, about 30 percent, of becoming a subtropical cyclone during the next 48 hours as it moves slowly toward the north-northwest and away from Florida and the oil rich Gulf of Mexico.

The U.S. National Oceanic and Atmospheric Administration (NOAA) will release its 2010 hurricane season forecast on Thursday.

The forecast is widely watched by energy and commodity markets for signs of potential weather disruptions to oil and gas installations in the Gulf of Mexico during the hurricane season.

The NHC is part of NOAA’s National Weather Service.

Some meteorologists have already predicted conditions are ripe for an unusually destructive hurricane season, which could also disrupt efforts to clean up BP’s oil spill in the Gulf of Mexico.

Commodities traders also watch for storms that could damage agriculture crops such as citrus and cotton in Florida and other states along the coast to Texas.

In addition, the path of a storm can affect pricing of insurance-linked securities, which transfer insurance risks associated with natural disasters to capital markets investors.

U.S. response to spill frustrates environmentalists

The U.S. government response to the BP oil spill has frustrated environmental groups and Gulf Coast conservationists, who say they’re getting scant information about the disaster’s potential ecological effects.

“There’s a lot of concern now about the marine impact and we’re not getting a truly transparent response from NOAA (the National Oceanic and Atmospheric Administration),” Aaron Viles of the Gulf Restoration Network said on Thursday.

Viles acknowledged that this kind of deep-water oil well blowout is unprecedented in U.S. waters, but said it should have been anticipated.

“There was no Plan B after the blowout preventer failed to contain, clean up or even estimate the environmental impact for marine and coastal communities,” he said by telephone from New Orleans.

Viles said his group has been concerned since the Deepwater Horizon oil rig exploded on April 20 that BP has exercised undue control over activities associated with this spill.

The Waterkeeper Alliance, a global environmental organization with members on the Gulf Coast, called for smarter integration of the response to the emergency and better support for coastal communities, along with better maps of oyster beds and fish and shrimp habitats.

NOAA did not immediately respond to a call for comment on Thursday about the environmental groups’ concerns.

Rick Steiner, a marine conservation specialist who responded to the 1989 Exxon Valdez oil tanker spill in Alaska, said it is likely that the oil now showing up on some Gulf beaches is only a fraction of what is being released from the broken underwater wellhead.

“UNCHARTED WATERS”

This subsurface oil is likely to mix with the deep water and stay in the water column, possibly endangering creatures that live in it or swim through it, before eventually rising to the surface in a plume, said Steiner, who is now affiliated with the environmental group Greenpeace.

He said chemical dispersants that were sprayed on the water’s surface will cause the surface oil to break up into small droplets that will become suspended in the water column, possibly contaminating fish that in turn will be eaten by birds and fed to newly hatched chicks.

“We don’t have enough damage assessment out there,” Steiner said in a telephone interview from the Gulf Coast. “NOAA has really, really dropped the ball here.”

NOAA chief Jane Lubchenco and Lisa Jackson, the head of the Environmental Protection Agency, offered few specifics in a briefing on Wednesday when asked about the environmental impact of dispersants.

“The monitoring that we are doing will enable us to get a better handle on what habitats will be affected if they are,” Lubchenco said. “Anything that we would say at this point is speculation.”

“When it comes to the environment we’re in unchartered waters,” Jackson said. “Every spill is different.”

One environmental fear is that the rust-colored light crude oil spewing from the mile-deep (1.6 km) offshore rig at the rate of 5,000 barrels (210,000 gallons/795,000 litres) a day will get enmeshed in the dense tall marsh grasses and reeds that fringe the Gulf Coast.

These reeds help stabilize the wetlands, which shelter wildlife and commercially important species including shrimp and oysters. If the reeds are fouled by oil, they could decline or die, leaving the shoreline even more vulnerable to erosion.

Because coastal marshes provide a buffer against storms in the Gulf of Mexico, slowing them down as they head inland, there would be less natural protection for developed areas in the event of a big hurricane. Hurricane season begins June 1.

INTERVIEW – Gulf oil spill might have surpassed Exxon Valdez

The Gulf of Mexico oil spill may already be bigger than the massive Exxon Valdez spill in 1989 and could have dumped as much as 13 million gallons (49 million litres) of crude into waters off the U.S. coastline, a Florida oceanographer said on Friday.

Ian MacDonald, a biological oceanographer at Florida State University, said official estimates that 5,000 barrels (210,000 gallons/795,000 litres) have poured into the Gulf each day since the Deepwater Horizon rig exploded two weeks ago were much too conservative.

The real flow rate from the undersea well, based on aerial images of the oil slick and estimates of the thickness of the oil itself, is probably closer to 25,000 barrels (1,050,000 gallons) per day, MacDonald said in an interview.

“We’ve been looking at … data and we see that the area of the Gulf which is covered by oil has been increasing rapidly, at a rate well in excess of a 1,000 square kilometers (386 square miles) a day,” he told Reuters.

“We see in excess of 10,000 (3,860 square miles) perhaps as much as 16,000 square kilometers (6,178 square miles) of oil-covered water, or water which has some indication that there’s oil there,” he said.

“We think that to get that much oil coverage we would to have to have flow rates well in excess of the 5,000 barrel per day rate and we’re putting this out as a high-end estimate,” MacDonald said.

A spokesperson for the National Oceanic and Atmospheric Administration, which has been monitoring the oil spill, said no one was immediately available to comment on possible revisions of the oil spill’s size.

MacDonald said the official estimate, used by NOAA, BP and the U.S. Coast Guard, had never been explained in detail and appeared to be little more than a guess.

The Exxon Valdez tanker ship spilled about 11 million gallons of oil into Alaska’s Prince William Sound, in one of the world’s worst environmental disasters ever.

If his own estimate is accurate, MacDonald said BP’s oil spill was already bigger than its 1989 rival.

“Our belief is that the overall amount of oil out there well exceeds the 5,000 barrel per day rate,” MacDonald said.

“I’m providing a thorough documentation of the methods that we’ve used,” he added.

MacDonald acknowleged that any estimate of the size of the spill, based on the surface area of the oil slick, could be flawed by a failure to correctly gauge the oil’s average thickness.

But he said he had worked together with NASA, and used some estimates provided by BP itself, to calculate the flow rate from the offshore oil well, almost 1 mile (1.6 km) below the Gulf of Mexico surface.

Tornado kills 10 in Mississippi: officials

(Reuters) – A tornado nearly a mile wide ripped through central Mississippi on Saturday, killing 10 people, including three children, and injuring dozens of others, state authorities said.

U.S.

The tornado struck at least 13 counties, destroying scores of homes and trapping people inside, damaging businesses, blocking highways and knocking out power to thousands, said the Mississippi Emergency Management Agency.

Five people died in Choctaw County, four in Yazoo County and one in Holmes County, said Greg Flynn, spokesman at the agency.

Governor Haley Barbour declared a state of emergency after the first major U.S. tornado of the year.

“It has done huge damage around Yazoo City,” Barbour, who grew up in the city, told CBS television.

“We have fatalities, a number of people that we’re still trying to rescue who are trapped in buildings. But it is a major, significant tornado … and it did some huge damage and perhaps some fatalities north of here,” Barbour said.

“The Hinds County Sheriff’s Department is sending two dozen deputies and 100 inmates to assist with the response in Yazoo County and clear debris,” the emergency agency said.

The storm system has moved to Tennessee, Alabama and Kentucky, said Greg Carbin, spokesman for the National Oceanic and Atmospheric Administration.

Sea levels rose as much as 2 feet this summer along the US East Coast

Washington, September 12 (ANI): Reports indicate that sea levels rose as much as 2 feet (60 centimeters) higher than predicted this summer along the US East Coast, surprising scientists who forecast such periodic fluctuations.

According to National Geographic News, though the immediate cause of the unexpected rise has now been solved, the underlying reason remains a mystery.

Usually, predicting seasonal tides and sea levels is a pretty cut-and-dried process, governed by the known movements and gravitational influences of astronomical bodies like the moon, according to Rich Edwing, deputy director for the Center for Operational Oceanographic Products and Services at the US National Oceanic and Atmospheric Administration (NOAA).

But, NOAA’s phones began ringing this summer when East Coast residents reported higher than predicted water levels, much like those associated with short-term weather events like tropical storms.

These high seas persisted for weeks, throughout June and July.

The startling rise caused only minor coastal flooding, but puzzled scientists.

Now, a new report has identified the two major factors behind the high sea levels-a weakened Gulf Stream and steady winds from the northeastern Atlantic.

The Gulf Stream is a northward-flowing superhighway of ocean water off the US East Coast.

Running at full steam, the powerful current pulls water into its “orbit” and away from the East Coast.

But this summer, for reasons unknown, “the Gulf Stream slowed down,” Edwing said, sending water toward the coasts-and sea levels shooting upward.

Adding to the sustained surge, autumn winds from the northeastern Atlantic arrived a few months early, pushing even more water coastward.

The higher waters caused inconveniences for some anglers and boaters and rearranged a bit of shoreline.

“A couple of sand beaches we’d normally fish from were eaten up. And the volume of water was higher than it normally would be,” said Paulie Apostolides, owner of Paulie’s Tackle in Montauk on New York State’s Long Island.

Even before the new report, released by NOAA on September 2, Apostolides said that many local fishers had already attributed the sea level rise to the “ferocious” winds from the northeast. (ANI)

US Navy ship sunk in World War II battle located

Washington, September 11 (ANI): A research mission has located and identified the final resting place of the YP-389, a US Navy patrol boat sunk approximately 20 miles off the coast of Cape Hatteras, North Carolina, by a German submarine during World War II.

Six sailors died in the attack on June 19, 1942. There were 18 survivors.

The wreck is located in about 300 feet of water in a region off North Carolina known as the “Graveyard of the Atlantic,” home to US and British naval vessels, merchant ships, and German U-boats sunk during the Battle of the Atlantic.

NOAA (National Oceanic and Atmospheric Administration) and its expedition partners mapped and shot video of the wreck using high-resolution camera equipment, multibeam sonar and an advanced remotely operated vehicle deployed from the NOAA ship Nancy Foster.

Researchers were able to locate and positively identify the YP-389 by reexamining data from the Duke Marine Laboratory expedition that discovered the USS Monitor in 1973.

Today, the relatively intact remains of the YP-389 rest upright on the ship’s keel.

The wreck site is home to a variety of marine life. Much of the outer-hull plating has fallen away, leaving only the intact frames exposed.

“She rests now like a literal skeleton, a reminder of a time long ago when the nation was at war,” said Joseph Hoyt, Monitor National Marine Sanctuary archaeologist and principal investigator for the project.

Built originally as a fishing trawler, the YP-389 was converted into a coastal patrol craft and pressed into service after the Japanese attack on Pearl Harbor.

The ship was equipped with one 3-inch deck gun to protect the ship from enemy aircraft and surfaced submarines and two .30-caliber machine guns.

However, on the day of the attack by the German submarine U-701, the ship’s deck gun was inoperative, and the YP-389 could return fire only with its machine guns.

Weeks after the attack on the YP-389, the U-701 was sunk by Army aircraft in the same vicinity as the YP-389.

According to Rear Admiral Jay A. DeLoach, USN (Ret), director, Naval History and Heritage Command, “The US Navy considers the YP-389 discovery a grave site and, by law, it is to be left undisturbed.” (ANI)

Killer whales have to raise their voices to be heard over ship noise

Washington, September 11 (ANI): A new research has determined that killer whales have to raise their voices to be heard over ship noise, and the effort may be wearing the whales out as they try to find food amid dwindling numbers of salmon.

According to a report in National Geographic News, scientists at the National Oceanic and Atmospheric Administration (NOAA) carried out the research.

The research indicates that the killer whales of Puget Sound, a complex of inland marine waterways in the northwestern part of Washington, US, make more calls and clicks while foraging than while traveling, suggesting that such mealtime conservations are key to coordinating hunts.

“(The killer whales’) call exchange is incredibly important, and vessel noises have the potential to mask these calls,” said research leader Marla Holt of Seattle’s Northwest Fisheries Science Center, which is run by the National Oceanic and Atmospheric Administration (NOAA).

Holt and colleagues’ previous research had shown that some killer whales make louder calls to be heard over vessel rumblings-just as people raise their voices to talk over the din of a cocktail party.

Now, the researchers think the cacophony could be causing the region’s killer whales to use up more energy during hunts, even as their preferred prey, chinook salmon, are on the decline.

In Puget Sound, a small group of killer whales known as the Southern Residents has been found to be particularly well-suited to eating salmon-even down to the whales’ tooth size.

These animals don’t eat seals or other mammals, as do the transient killer whales that migrate through the sound.

In the mid- to late 1990s, the Southern Resident population mysteriously shrank by nearly 20 percent, from 97 to 88 animals. Today, there are 85 individuals.

In 2005, the federal government listed the population as endangered under the US Endangered Species Act.

No one knows for sure, but the cause was likely a combination of fewer salmon, exposure to toxic contaminants, and vessel noise, according to Lynne Barre of NOAA’s National Marine Fisheries Service Northwest Regional Office.

Holt’s work adds to existing data that have already prompted NOAA to propose a new killer whale protection law that would make all boats keep at least 600 feet (200 yards) away from the animals around Washington State.

The existing law allows boats to approach as close as 300 feet (100 yards), and some research has shown this influences the whales’ behavior.

“A lot of people would argue, Why focus on these vessel regulations?” Holt said. “But it’s one thing we can do immediately,” he added. (ANI)

Human impacts and environmental factors changing northwest Atlantic ecosystem

Washington, Sept 2 (ANI): A new report by researchers at the National Oceanic and Atmospheric Administration (NOAA) has determined that human impacts and environmental factors are changing the northwest Atlantic ecosystem.

According to the report, fish in US waters from Cape Hatteras to the Canadian border have moved away from their traditional, long-time habitats over the past four decades because of fundamental changes in the regional ecosystem.

The 2009 Ecosystem Status Report also points out the need to manage the waters off the northeastern coast of the United States as a whole rather than as a series of separate and unrelated components.

Known as the Northeast US Continental Shelf Large Marine Ecosystem (NES LME), the ecosystem spans approximately 100,000 square miles and supports some of the highest revenue-generating fisheries in the nation.

During the past 40 years, the ecosystem has experienced extensive fishing by domestic and foreign fleets, changes in ocean water temperatures due to climate change, and pressures from increasing human populations along the coast.

According to Michael Fogarty, who heads the Ecosystem Assessment Program at the Northeast Fisheries Science Center (NEFSC) of NOAA’s Fisheries Service in Woods Hole, Massachusetts, his team’s report highlights the need to understand natural and human-related changes in this region and to develop effective management and mitigation strategies.

“There are many pressures on the ecosystem including fishing, pollution, habitat loss from coastal development, and impacts on marine life from shipping and other uses of the ocean,” Fogarty said.

“In addition, changing climate conditions are warming ocean waters, changing ocean chemistry and circulation patterns, and altering atmospheric systems. These changes have, in turn, been linked to changes in the distribution and abundance of fish species in the region and their major sources of food,” he added.

The report is the first in a planned series of ecosystem status reports by Fogarty and his colleagues in the NEFSC’s Ecosystem Assessment Program to document changes in the NES LME, one of 64 regions in the world’s ocean designated as a large marine ecosystem.

Fogarty said that sustained long-term monitoring by many agencies and institutions in the Northeast region has enabled scientists and others to trace changes in the ecosystem.

“In the future, we need to continue to monitor the oceanographic, ecological, and human indicators analyzed in this report to detect any additional changes in the system. These indicators also provide important inputs to models that can be used to help guide management decisions and to forecast future changes,” he said. (ANI)

El Nino – El Nino 2009 – El Nini Effect – El Nino conditions return to affect weather

El Nino – El Nino 2009 – El Nini Effect – El Nino conditions return to affect weather

WASHINGTON (AP) — El Nino is back.

Government scientists said Thursday that the periodic warming of water in the tropical Pacific Ocean, which can affect weather around the world, has returned.

The Pacific had been in what is called a neutral state, but forecasters at the National Oceanic and Atmospheric Administration say the sea surface temperature climbed to 1.8 degrees Fahrenheit above normal along a narrow band in the eastern equatorial Pacific in June.

In addition, NOAA’s Climate Prediction Center said temperatures in other tropical regions are also above normal, with warmer than usual readings as much as 975 feet below the ocean surface.

In general, El Nino conditions are associated with increased rainfall across the east-central and eastern Pacific and with drier than normal conditions over northern Australia, Indonesia and the Philippines.

A summer El Nino can lead to wetter than normal conditions in the intermountain regions of the United States and over central Chile. In an El Nino year there tend to be more Eastern Pacific hurricanes and fewer Atlantic hurricanes.

The forecasters said they expect this El Nino to continue strengthening over the next few months and to last through the winter of 2009-2010.

“Advanced climate science allows us to alert industries, governments and emergency managers about the weather conditions El Nino may bring so these can be factored into decision-making and ultimately protect life, property and the economy,” NOAA Administrator Jane Lubchenco said in a statement.

NOAA officials noted that not all El Nino effects are negative. For example, it can suppress Atlantic hurricanes and bring needed moisture to the arid Southwest.

But it can also steer damaging winter storms to California and increase storminess across the southern United States.

The warming of the ocean can also lead to a reduction in the seafood catch off the West Coast, and fewer fish can also impact food sources for several types of birds and marine mammals.

A recent study by researchers at Georgia Tech suggests there may actually be two forms of El Nino, depending on whether the warming is stronger in the eastern or central pacific.

While the current warming seems to be strongest in the east, the more traditional form, government forecasters did not categorize it.

If the Georgia Tech study is correct, this would be the type of El Nino that reduces hurricanes in the Atlantic and Caribbean. The other form, centered farther west, reportedly seems to promote Atlantic storms.

NASA and NOAA’S GOES-O satellite launched successfully

Washington, June 28 (ANI): The latest Geo-stationary Operational Environmental Satellite, GOES-O, soared into space Saturday after a successful launch from Space Launch Complex 37 at the Cape Canaveral Air Force Station in Florida.

The GOES-O spacecraft lifted off at 6:51 p.m. EDT on a Delta IV rocket.

The National Oceanic and Atmospheric Administration’s GOES-O satellite will improve weather forecasting and monitor environmental events around the world.

The satellite is the second to be launched in the GOES N series of geo-stationary environmental weather satellites.

“All indications are that GOES-O is in a normal orbit, with all spacecraft systems functioning properly,” stated Andre Dress, GOES deputy project manager at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

“We are proud of our support teams and pleased with the performance of the Delta IV launch vehicle,” he added.

Approximately four hours and twenty-one minutes after the launch, the spacecraft separated from the launch vehicle.

The Universal Space Network Western Australia tracking site in Dongara monitored the spacecraft separation.

On July 7, GOES-O will be placed in its final orbit and renamed GOES-14.

Approximately 24 days after launch, Boeing Space and Intelligence Systems will turn engineering control over to NASA.

About five months later, NASA will transfer operational control of GOES-14 to NOAA. The satellite will be checked out, stored in orbit and available for activation should one of the operational GOES satellites degrade or exhaust its fuel.

NASA contracted with Boeing to build and launch the GOES-O spacecraft.

NASA’s Launch Services Program at NASA’s Kennedy Space Center in Florida supported the launch in an advisory role.

The NOAA manages the GOES program, establishes requirements, provides all funding and distributes environmental satellite data for the United States.

Goddard procures and manages the design, development and launch of the satellites for NOAA on a cost-reimbursable basis. (ANI)

Dry autumns and winters may lead to fewer tornadoes in the spring

Washington, June 25 (ANI): A new study by researchers at the University of Georgia, US, has determined that global warming may mean dry autumns and winters that may lead to fewer tornadoes in the spring.

The study pins down, possibly for the first time, how drought conditions in an area’s fall and winter may affect tornado activity the following spring.

The study is specific to Georgia and the Southeast, but further study could reveal patterns that might make this more general, including the already tornado-prone Great Plains.

“Our results suggest that there is a statistically significant reduction in tornado activity during a tornado season following drought the preceding fall and winter,” said Marshall Shepherd, a meteorologist and lead author of the study.

On the other hand, wet autumns and winters examined in the study had nearly twice as many spring tornado days as drought years did.

The research gives hope that one day meteorologists and climatologists may be able to predict the severity of a spring tornado season the way they now do for hurricanes.

The genesis for the research was the severe Atlanta tornado in March 2008, and Shepherd’s interest in how tornadoes form during severe drought years.

To help understand how fall and winter weather might affect spring tornado seasons, the research team acquired the historical database of severe thunderstorms and tornado occurrences from 1951-2006 from the Storm Prediction Center of the National Oceanic and Atmospheric Administration.

They also analyzed storm data reports from the National Climactic Data Center and meteorological drought conditions using historical rain gauge and Tropical Rainfall Measuring Mission (TRMM) satellite data from the National Aeronautics and Space Administration (NASA).

Using a number of tools of scientific analysis, the team primarily focused on tornado activity from March-June in Georgia and the Southeast. What they found was shocking, Shepherd said, yet plausible.

On average, wet autumns and winters presaged nearly twice as many spring tornado days in the study area as prior drought seasons.

Springs following wet winters and falls were also five to six times more likely to have multiple tornado days than antecedent drought years.

“We do not suggest that soil moisture or precipitation the previous fall and winter exert a direct control on which individual storms will spawn tornadoes,” said Shepherd. “But these long-term seasonal relationships in the study area are striking,” he added. (ANI)

Endangered right whales found where there were none

Washington, May 21 (IANS) Scientists have documented the presence of endangered North Atlantic right whales with the help of underwater hydrophones that can pick up sounds from hundreds of kilometres away.

The discovery is particularly important because it is in an area where these whales were thought to be extinct and one that may be opened to shipping if the melting of polar ice continues, as expected, said researchers.

Scientists from Oregon State University (OSU) and the National Oceanic and Atmospheric Administration (NOAA) are unsure of exactly how many whales were in the region, which is off the southern tip of Greenland and site of an important 19th-century whaling area called Cape Farewell Ground.

But they recorded more than 2,000 right whale vocalisations in the region from July through December of 2007.

‘The technology has enabled us to identify an important unstudied habitat for endangered right whales and raises the possibility that… a remnant of a central or eastern Atlantic stock of right whales still exists and might be viable,’ said David Mellinger, assistant professor at OSU Hatfield Marine Science Centre in Newport and chief project scientist.

‘We don’t know how many right whales there were in the area,’ Mellinger added. ‘They aren’t individually distinctive in their vocalisations. But we did hear right whales at three widely spaced sites on the same day, so the absolute minimum is three. Even that number is significant because the entire population is estimated to be only 300 to 400 whales.’

Only two right whales have been sighted in the last 50 years at Cape Farewell Ground, where they had been hunted to near extinction prior to the adoption of protective measures, said an OSU release.

The results were presented this week at the Acoustical Society of America in Portland, Oregon.

Endangered whales found where presumed extinct

Washington, May 21 (ANI): A team of scientists, using a system of underwater hydrophones that can record sounds from hundreds of miles away, has documented the presence of endangered North Atlantic right whales in an area they were thought to be extinct.

The scientists are from the Oregon State University (OSU) and the National Oceanic and Atmospheric Administration (NOAA).

According to the researchers, the discovery is particularly important because it is in an area that may be opened to shipping if the melting of polar ice continues, as expected.

The scientists are unsure of exactly how many whales were in the region, which is off the southern tip of Greenland and site of an important 19th-century whaling area called Cape Farewell Ground.

But, they recorded more than 2,000 right whale vocalizations in the region from July through December of 2007.

“The technology has enabled us to identify an important unstudied habitat for endangered right whales and raises the possibility that – contrary to general belief – a remnant of a central or eastern Atlantic stock of right whales still exists and might be viable,” said David Mellinger, an assistant professor at OSU’s Hatfield Marine Science Center in Newport and chief scientist of the project.

“We don’t know how many right whales there were in the area,” Mellinger added.

“They aren’t individually distinctive in their vocalizations. But, we did hear right whales at three widely space sites on the same day, so the absolute minimum is three. Even that number is significant because the entire population is estimated to be only 300 to 400 whales,” he further added.

Only two right whales have been sighted in the last 50 years at Cape Farewell Ground, where they had been hunted to near extinction prior to the adoption of protective measures.

According to Mellinger, Right whales produce a variety of sounds, and through careful analysis, these sounds can be distinguished from other whales.

The scientists used recordings of North Atlantic and North Pacific right whales to identify the species’ distinct sounds, including vocalizations known as “up” calls.

Beginning in July of 2007, the scientists recorded a total of 2,012 calls in the North Atlantic off Greenland.

The pattern of recorded calls suggests that the whales moved from the southwest portion of the region in a northeasterly direction in late July, and then returned in September – putting them directly where proposed future shipping lanes would be likely. (ANI)

Sun’s new solar cycle will be weakest since 1928

London, May 11 (ANI): A panel of international experts has predicted that the Sun’s new solar cycle, which is thought to have begun in December 2008, will be the weakest since 1928.

Solar activity waxes and wanes every 11 years.

Cycles can vary widely in intensity, and there is no foolproof way to predict how the sun will behave in any given cycle.

In 2007, an international panel of 12 experts split evenly over whether the coming cycle of activity, dubbed Cycle 24, would be stronger or weaker than average.

The group did agree the sun would probably hit the lowest point in its activity in March 2008 before ramping up to a new cycle that would reach its maximum in late 2011 or mid-2012.

But, the sun did not bear out those predictions.

Instead, it entered an unexpectedly long lull in activity with few new sunspots. It is thought to have reached its minimum in December 2008, and now seems to be slowly waking up.

According to a report in New Scientist, one such sign is two new active regions captured this week by the ultraviolet camera on one of NASA’s twin STEREO probes.

“There’s a lot of indicators that Cycle 24 is ready to burst out,” said panel chair Doug Biesecker of the National Oceanic and Atmospheric Administration Space Weather Prediction Center in Boulder, Colorado.

The panel now expects the sun’s activity will peak about a year late, in May 2013, when it will boast an average of 90 sunspots per day.

That is below average for solar cycles, making the coming peak the weakest since 1928, when an average of 78 sunspots was seen daily.

Sunspots are Earth-sized blotches that coincide with knotty magnetic fields. They are a common measure of solar activity.

The higher the number of sunspots, the higher the probability of a major storm that could wreak havoc on Earth.

A lower number of sunspots could mean space weather will be relatively mild in the coming years. (ANI)

Pachauri warns melting of glaciers could adversely impact river systems

New Delhi, Apr 6 (ANI): United Nation’s climate panel chief and Nobel laureate R K Pachauri has said melting glaciers could adversely impact river systems in India.

“If you look at the impact of melting of glaciers, it is not only reduction in supply in the river system but this will also have an impact on recharge of ground water because rivers plays an extremely important function in recharging ground water resources. As a result of excessive exploitation of ground water, we already have a major decline in the water table in several parts of the country. Climate change is going to add to this problem,” Pachauri said.

The UN Climate Panel projects that world atmospheric temperature will rise by between 1.8 and 4.0 degrees Celsius because of emissions of greenhouse gases that could bring floods, droughts, heat waves and more powerful storms.

As glaciers and ice sheets melt, they can raise overall ocean levels and swamp low-lying areas.

One Antarctic ice shelf has quickly vanished, another is disappearing and glaciers are melting faster than anyone thought due to climate change, U.S. and British Government researchers reported on Friday.

They said the Wordie Ice Shelf, which had been disintegrating since the 1960s, is gone and the northern part of the Larsen Ice Shelf no longer exists.

More than 3,200 square miles have broken off from the Larsen shelf since 1986.

In another report published in the journal Geophysical Letters, the National Oceanic and Atmospheric Administration reports that ice is melting much more rapidly than expected in the Arctic as well, based on new computer analyses and recent ice measurements. (ANI)

Reduction in airborne dust responsible for recent warming trend in Atlantic Ocean

Washington, March 27 (ANI): A new study has determined that the recent warming trend in the Atlantic Ocean is largely due to reductions in airborne dust and volcanic emissions during the past 30 years.

Since 1980, the tropical North Atlantic has been warming by an average of a quarter-degree Celsius (a half-degree Fahrenheit) per decade.

“Though this number sounds small, it can translate to big impacts on hurricanes, which thrive on warmer water,” said Amato Evan, a researcher with the University of Wisconsin-Madison’s Cooperative Institute for Meteorological Satellite Studies and lead author of the new study.

For example, the ocean temperature difference between 1994, a quiet hurricane year, and 2005′s record-breaking year of storms, was just one degree Fahrenheit.

More than two-thirds of this upward trend in recent decades can be attributed to changes in African dust storm and tropical volcano activity during that time, report Evan and his colleagues at the UW-Madison and the National Oceanic and Atmospheric Administration.

In the new study, they combined satellite data of dust and other particles with existing climate models to evaluate the effect on ocean temperature.

They calculated how much of the Atlantic warming observed during the last 26 years can be accounted for by concurrent changes in African dust storms and tropical volcanic activity, primarily the eruptions of El Chichon in Mexico in 1982 and Mount Pinatubo in the Philippines in 1991.

In fact, it is a surprisingly large amount.

“A lot of this upward trend in the long-term pattern can be explained just by dust storms and volcanoes,” said Evans.

“About 70 percent of it is just being forced by the combination of dust and volcanoes, and about a quarter of it is just from the dust storms themselves,” he added.

The result suggests that only about 30 percent of the observed Atlantic temperature increases are due to other factors, such as a warming climate.

While not discounting the importance of global warming, Evan said that this adjustment brings the estimate of global warming impact on Atlantic more into line with the smaller degree of ocean warming seen elsewhere, such as the Pacific.

“This makes sense, because we don’t really expect global warming to make the ocean temperature increase that fast,” he said. (ANI)

Tsunami warning issued for Fiji, Samoa

Washington – The US-based National Oceanic and Atmospheric Administration (NOAA) on Thursday issued a tsunami warning for Tonga, Samoa and Fiji among other Pacific islands.

The warning came after a 7.7-magnitude earthquake was reported 10 kilometres deep in the Tonga islands region.

“Sea level readings confirm that a tsunami was generated. This tsunami may have been destructive along coastlines of the region near the earthquake epicentre,” a NOAA statement said, alerting authorities in the region.

The NOAA said that boats and coastal structures were in danger because of the rapid currents. A tsunami is a series of powerful and successive waves that can occur anywhere between five minutes to one hour apart.

Other islands alerted included Niue, Kermadec, American Samoa and Walli-Futuna. (dpa)

Huge CO2 releases may have amplified global warming at end of last ice age

Washington, March 13 (ANI): A new research has suggested that natural releases of carbon dioxide from the Southern Ocean due to shifting wind patterns could have amplified global warming at the end of the last ice age, and could be repeated as manmade warming proceeds.

The research was conducted by a team of scientists at Columbia University’s Lamont-Doherty Earth Observatory, US.

Many scientists think that the end of the last ice age was triggered by a change in Earth’s orbit that caused the northern part of the planet to warm.

This partial climate shift was accompanied by rising levels of the greenhouse gas CO2, ice core records show, which could have intensified the warming around the globe.

Now, the team from Lamont-Doherty Earth Observatory has offered one explanation for the mysterious rise in CO2.

According to them, the orbital shift triggered a southward displacement in westerly winds, which caused heavy mixing in the Southern Ocean around Antarctica, pumping dissolved carbon dioxide from the water into the air.

“The faster the ocean turns over, the more deep water rises to the surface to release CO2,” said lead author Robert Anderson, a geochemist at Lamont-Doherty. “It’s this rate of overturning that regulates CO2 in the atmosphere,” he added.

In the last 40 years, the winds have shifted south much as they did 17,000 years ago, said Anderson.

If they end up venting more CO2 into the air, manmade warming underway now could be intensified.

Two years ago, J.R. Toggweiler, a scientist at the National Oceanic and Atmospheric Administration (NOAA), proposed that westerly winds in the Southern Ocean around Antarctica may have undergone a major shift at the end of the last ice age.

This shift would have raised more CO2-rich deep water to the surface, and thus amplified warming already taking place due to the earth’s new orbital position.

Anderson and his colleagues are the first to test that theory by studying sediments from the bottom of the Southern Ocean to measure the rate of overturning.

According to the scientists, changes in the westerlies may have been triggered by two competing events in the northern hemisphere about 17,000 years ago.

The earth’s orbit shifted, causing more sunlight to fall in the north, partially melting the ice sheets that then covered parts of the United States, Canada and Europe.

“Now I think this really starts to lock up how the CO2 changed globally,” said Toggweiler. “Here’s a mechanism that can explain the warming of Antarctica and the rise in CO2. It’s being forced by the north, via this change in the winds,” he added. (ANI)
