The Woods Hole Oceanographic Institution says it will soon begin construction of ocean observatories at various U.S. coastal sites and other locations. An agreement concerning the project was signed Wednesday by officials of the institution, the National Science Foundation and the Consortium for Ocean Leadership. The ocean observatories will be located off southern New England, Oregon and Washington, as well as at high latitude open ocean sites in the Atlantic, Pacific and Southern Oceans....

New evidence for ice-free summers with intermittent winter sea ice in the Arctic Ocean during the Late Cretaceous "“ a period of greenhouse conditions - gives a glimpse of how the Arctic is likely to respond to future global warming.Records of past environmental change in the Arctic should help predict its future behaviour. The Late Cretaceous, the period between 100 and 65 million years ago leading up to the extinction of the dinosaurs, is crucial in this regard because levels of...

Southampton scientists have demonstrated an unexpected role of iron in regulating biological production in the high-latitude North Atlantic. Their findings have important implications for our understanding of ocean-climate interactions.Tiny plant-like organisms called phytoplankton dominate biological production in the sunlit surface waters of the world's oceans and, through the process of photosynthesis, sequester large amounts of atmospheric carbon dioxide. A proportion of the carbon is...

Does ozone have an impact on the ocean's role as a "carbon sink"? Yes, according to researchers from three laboratories (1) attached to INSU-CNRS (2), UPMC, CEA, IRD, MNHN and UVSQ. Using original simulations, they have demonstrated that the hole in the ozone layer reduces atmospheric carbon uptake in the Southern Ocean and contributes to the increase in ocean acidity. These results, which are published online in the journal Geophysical Research Letters, should have a considerable impact on...

Plankton blooms do not send atmospheric carbon to the deep ocean Oceanographers Jim Bishop and Todd Wood of the U.S. Department of Energy's Lawrence Berkeley National Laboratory have measured the fate of carbon particles originating in plankton blooms in the Southern Ocean, using data that deep-diving Carbon Explorer floats collected around the clock for well over a year. Their study reveals that most of the carbon from lush plankton blooms never reaches the deep ocean. The surprising...

A hole in the ozone has resulted in a growth of Antarctic sea ice over the past 30 years, according to a report released on Tuesday. Scientists from the British Antarctic Survey (BAS) and NASA reported the ozone hole has resulted in changing weather patterns that have caused a small rise in the amount of Antarctic sea ice, while Arctic sea ice has seen a dramatic loss. Sea ice is a crucial part of the Earth's ecosystems. It acts as a reflector against the sun's heat, and provides a habitat...

Antarctic Treaty Consultative Meeting explores global warming's effect on marine resources WASHINGTON, April 6 /PRNewswire-USNewswire/ -- On the eve of a historic 11-day meeting celebrating the 50th anniversary of the Antarctic Treaty, the Pew Environment Group encouraged diplomats, polar scientists and non-governmental organizations to redouble their efforts to protect polar regions from the impact of climate change. The Antarctic Treaty Consultative Meeting (ATCM) is the major annual...

An efficient network of specialists, data and tools to explore and safeguard Antarctica formed as legacy of IPY The International Polar Year (IPY) concluded in March 2009 with a tangible legacy in the form of a network of databases on marine biodiversity that will serve as clearinghouse for all biodiversity-related data gathered since the very first Antarctic research expeditions. The network gathers data describing the species themselves as well as information about their collection history,...

Scientists in Germany and India said an experiment to determine whether depositing hundreds of tons of dissolved iron in the Southern Ocean can diminish global warming has produced disappointing results. In conducting the research, scientists "fertilized" a 115 square mile area of ocean by placing six tons of dissolved iron inside the core of an eddy -- a large, rotating column of water. The researchers hoped the iron would stimulate the growth of tiny planktonic algae known as phytoplankton,...

In the Southern Indian Ocean, climate change is leading to stronger winds, which mix waters, bringing CO2 up from the ocean depths to the surface. This is the conclusion of researchers who have studied the latest field measurements carried out by CNRS's INSU, IPEV and IPSL. As a result, the Southern Ocean can no longer absorb as much atmospheric CO2 as before. Its role as a 'carbon sink' has been weakened, and it may now be ten times less efficient than previously estimated. The same trend...

The White-chinned Petrel (Procellaria aequinoctialis), is a large seabird in the family Procellariidae. It ranges around the Southern Ocean as far north as South Australia, Peru and Namibia, and breeds colonially on scattered islands; South Georgia, Prince Edward Islands, Crozet Islands, Kerguelen Islands, Auckland Island, Campbell Island and Antipodes Islands. The diet of the White-chinned Petrel is composed mainly of krill, followed by fish. White-chinned Petrels feed by surface...

The Southern driftfish or ragfish, Icichthys australis, is a medusafish of the genus Icichthys found circumpolar in all southern oceans between latitudes 50° S and 60° S, from the surface down to 1.24 mi (2,000 m). Its length is from 13.78 to 31.50 in (35 to 80 cm). The southern driftfish is similar to the rudderfish, and has soft easily-damaged fins, large eyes, and a small flexible mouth. Its flesh is soft and its bones are weakly ossified, giving rise to its second common name as...

The Wandering Albatross, (Diomedea exulans), is a large seabird from the family Diomedeidae which has a circumpolar range in the Southern Ocean. At breeding time they occupy loose colonies on isolated island groups in the Southern Ocean, such as Crozet Islands, South Georgia, Marion Island, Prince Edward Island, Kerguelen and Macquarie Island. Together with the Tristan, Antipodean and Amsterdam Albatross it forms the Wandering Albatross species complex. The Wandering Albatross has the...
