Global Warming Threatens Antarctic Sea Life ScienceDaily (Feb. 9, 2009) — Climate change is about to cause a major upheaval in the shallow marine waters of Antarctica. Predatory crabs are poised to return to warming Antarctic waters and disrupt the primeval marine communities. "Nowhere else than in these ecosystems do giant sea spiders and marine pillbugs share the ocean bottom with fish that have antifreeze proteins in their blood," says Rich Aronson, professor of biological sciences at Florida Institute of Technology in Melbourne, Fla. "The shell-cracking crabs, fish, sharks and rays that dominate bottom communities in temperate and tropical zones have been shut out of Antarctica for millions of years because it is simply too cold for them." But this situation is about to change. "Populations of predatory king crabs are already living in deeper, slightly warmer water," says Aronson. "And increasing ship traffic is introducing exotic crab invaders. When ships dump their ballast water in the Antarctic seas, marine larvae from as far away as the Arctic are injected into the system." Fast-moving, shell-crushing predators, dominant in most places, cannot operate in the icy waters of Antarctica. The only fish there—the ones with the antifreeze proteins—eat small, shrimp-like crustaceans and other soft foods. The main bottom dwelling predators are slow-moving sea stars and giant, floppy ribbon worms. To understand their history, Aronson and a team of paleontologists collected marine fossils at Seymour Island off the Antarctic Peninsula. Linda Ivany of Syracuse University reconstructed changes in the Antarctic climate from chemical signals preserved in ancient clamshells. As temperatures dropped about 41 million years ago and crabs and fish were frozen out, the slow-moving predators that remained could not keep up with their prey. Snails, once out of danger, gradually lost the spines and other shell armor they had evolved against crushing predators. Antarctica's coastal waters are warming rapidly. Temperatures at the sea surface off the western Antarctic Peninsula went up 1°C in the last 50 years, making it one of the fastest-warming regions of the World Ocean.

Ocean warming threatens Antarctic wildlife · Sea ice melts and glaciers shrink at accelerating rate · Decline in stocks of krill hits entire food chain * David Adam, environment correspondent * The Guardian, Wednesday 19 October 2005 Scientists working in Antarctica have discovered an alarming rise in sea temperature that threatens to disrupt populations of penguins, whales, seals and a host of smaller creatures within a few decades. The new study shows the ocean west of the Antarctic Peninsula has warmed by more than a degree since the 1960s - confounding computer models and experts who believed that a combination of ice, winds and currents would keep the water cool and shield fragile marine creatures from the effects of climate change. This is the first evidence that the key Southern Ocean is getting warmer: a finding with potentially severe implications for wildlife. guardian.co.uk © Guardian News and Media Limited 2010 ... The impact of global warming in Antarctica The impacts of warming temperatures in Antarctica are likely to occur first in the northern sections of the continent, where summer temperatures approach the melting point of water, 32�F (0�C). Some ice shelves in the northernmost part of Antarctica—the Antarctic Peninsula—have been collapsing in recent years, consistent with the rapid warming trend there since 1945. Scientists are also concerned about future changes in the large West Antarctic ice sheet on the main continent because its collapse could raise sea level by as much as 19 feet (5.8 meters). Fingerprints 70. Antarctic Peninsula -- Warming 5 times global average. Since 1945, the Antarctic Peninsula has experienced a warming of about 4.5�F (2.5�C). The annual melt season has increased by 2 to 3 weeks in just the past 20 years. 73. Antarctica -- Ice shelf disintegration. The 770 square mile (1,994 km2) Larsen A ice shelf disintegrated suddenly in January 1995. 74. Antarctica -- Ice shelf breakup. After 400 years of relative stability, nearly 1,150 square miles (2,978 km2) of the Larson B and Wilkins ice shelves collapsed between March 1998 and March 1999. 122. Southern Ocean - Strong warming trend. Measurements from data recorders in the Southern Ocean waters around Antarctica show a 0.3�F (0.17�C) rise in ocean temperatures between the 1950s and the 1980s. 140. Antarctica - Decreasing Ice-thickness. The permanent ice cover of nine lakes on Signey Island has decreased by about 45% since the 1950s. Average summer air temperature has warmed by 1.8�F (1�C). 141. Antarctic Peninsula - Collapsing ice-shelf, January-February 2002. The northern section of the Larsen B ice shelf, an area of 1,250 square miles (3,250 km2), disintegrated in a period of 35 days. This was the largest collapse event of the last 30 years, bringing the total loss of ice extent from seven ice shelves to 6,760 square miles (17,500 km2) since 1974. The ice retreat is attributed to the region�s strong warming trend - 4.5�F (2.5�C) in the last 50 years. Harbingers 32. Antarctica -- Penguin population decline. Adelie Penguin populations have shrunk by 33% during the past 25 years in response to declines in their winter sea ice habitat. The new study shows the ocean west of the Antarctic Peninsula has warmed by more than a degree since the 1960s - confounding computer models and experts who believed that a combination of ice, winds and currents would keep the water cool and shield fragile marine creatures from the effects of climate change.

Global warming science is indeed interesting but the trumped up anti-science cult of AGW denial is extremely pathetic and totally stupid.

Here's a new report of an Antarctic glacier calving a huge iceberg with potentially far ranging effects.
Antarctic spits out iceberg the size of Luxembourg Hannah Devlin The London Times February 27, 2010 An iceberg the size of Luxembourg has split off from the Antarctic continent and could disrupt global ocean patterns and weather systems for decades, according to scientists. The 985 sq mile (2,550 sq km) block of ice was knocked off the Mertz Glacier Tongue, a spit of floating ice protruding from eastern Antarctica, on February 12 or 13. It was dislodged by an older iceberg, known as B9B, which broke off in 1987. Top: the 60 mile long B9B Iceberg shown about to crash into the Mertz Glacier Tongue on January 7. Middle: The iceberg making contact with the Glacier on February 7. Bottom: a huge chuck breaks off the glacier forming a new, 48 mile, long iceberg on February 20. - (Commonwealth of Australia/AP) Although the impact will not be felt for decades, the iceberg could block the production of cold, salty water, known as “bottom water”, which could lead eventually to cooler winters in the North Atlantic. It could also have a negative impact on some of Antarctica’s wildlife, including a large colony of emperor penguins based near by. A reduction in open water may mean they have to travel farther afield to find food. “The ice tongue was almost broken already. It was hanging like a loose tooth,” said Benoit Legresy, who works at the Laboratory for Geophysics and Oceanographic Space Research in Toulouse. His team, in collaboration with Australian scientists, has been monitoring the Mertz Glacier via satellite images and on the ground for a decade. After remaining jammed against the Antarctic continent for 20 years, B9B began to drift last year, approaching the Mertz like a slow-motion battering ram. “It gave it a pretty big nudge,” said Neal Young, a glaciologist at the Antarctic Climate and Ecosystems Research Centre in Tasmania. Since the collision, the iceberg and the newly mobile B9B, which is about the same size, have moved into an area called a polynya. Distributed across the Southern Ocean, polynyas are zones producing dense water, super-cold and rich in salt, that sink to the sea bottom and drive the conveyor-belt-like circulation around the globe. If the icebergs move east and run aground, or drift north into warmer seas, they will have no impact on the global convection system. But if they stay in the area — which scientists say is likely — they could partly block the production of the dense water, essentially putting a lid on the polynya’s action. The Mertz Glacier Polynya accounts for about 20 per cent of the bottom water in the world, and so over decades — the timescale on which the currents circulate — the impact could be significant. A slowing down of production of bottom water would mean less oxygen going into the deep currents that feed the oceans. “There may be regions of the world’s oceans that lose oxygen, and then of course, most of the life there will die,” said Mario Hoppema, chemical oceanographer at the Alfred Wegener Institute for Polar and Marine Research in Germany. However, Michael Meredith, polar oceans specialist at the British Antarctic Survey, said any measurable change in oxygenation was likely to be localised to Antarctica. The carving off of ice shelves and collapse of glaciers are part of Antarctica’s natural cycle, but man-made climate change could accelerate the processes. “Obviously when there is warmer water, these ice tongues will become more fragile,” Dr Legresy said. The Mertz Glacier Tongue has been under close scientific scrutiny for the past decade and is fitted with GPS beacons and other measuring instruments, meaning scientists will have a record of the calving event — before, during and after. “We are using the ice tongue as a laboratory to study the processes that might be impacted by climate change, including calving, ocean temperature, sea level change,” Dr Legresy said.
