Kiwi scientists set sail for Antarctic expeditionNew Zealand Herald | 03 Feb 2013
An international team of scientists has set sail from Wellington to study how changes to an Antarctic ocean region could affect global ocean circulations. Twenty-two scientists including researchers from New Zealand, Australia and France departed on the Niwa research vessel Tangaroa this morning for a 42-day voyage to the Mertz Polynya region of Antarctica.
Lamont oceanographer recognized for pioneering work on global ocean currentsEurekAlert | 31 Jan 2013
(The Earth Institute at Columbia University) An oceanographer who has painstakingly collected measurements from each of the world's oceans to understand how the oceans move heat and freshwater around the planet to influence climate is the winner of the 2013 Prince Albert 1 Medal for outstanding contributions to oceanography, given by the International Association for the Physical Sciences of the Ocean.
Scientist: Ozone thinning has changed ocean circulationEurekAlert | 31 Jan 2013
(Johns Hopkins University) A hole in the Antarctic ozone layer has changed the way that waters in the southern oceans mix, a situation that has the potential to alter the amount of CO2 in the atmosphere and eventually could have an impact on global climate change.
Tracing the origin of Arctic driftwoodonlinelibrary.wiley.com | 29 Jan 2013
Driftwood may represent a unique cross-disciplinary archive at the interface of marine and terrestrial processes. Here, we introduce 1,445 driftwood remains from coastal East Greenland and Svalbard. To ultimately reconstruct spatiotemporal variations in ocean currents, and to better quantify postglacial uplift rates, we recommend consideration of dendrochronologically dated material from many more circumpolar sites.
Investigating ocean currents using uranium-236 from the 1960sEurekAlert | 17 Dec 2012
Stephan Winkler, Isotope researcher at the University of Vienna, has identified the bomb-pulse of uranium-236 in corals from the Caribbean Sea for the first time. 236U was distributed world-wide in the period of atmospheric nuclear testing in the 1960s. Readily dissolved in seawater it is an ideal tool for investigating ocean currents.
Warm sea water is melting Antarctic glaciersEurekAlert | 06 Dec 2012
The ice sheet in West Antarctica is melting faster than expected. New observations published by oceanographers from the University of Gothenburg and the US may improve our ability to predict future changes in ice sheet mass. The study was recently published in the journal Nature Geoscience.
UMass Amherst climate modeler identifies trigger for Earth's last big freezeEurekAlert | 05 Nov 2012
"This episode was the last time the Earth underwent a major cooling, so understanding exactly what caused it is very important for understanding how our modern-day climate might change in the future," says Condron of UMass Amherst's Climate System Research Center. Findings appear in the current issue of Proceedings of the National Academy of Sciences.
Mathematics and the ocean: Movement, mixing and climate modelingEurekAlert | 18 Oct 2012
Studying the dynamics of the ocean system can greatly improve our understanding of key processes of ocean circulations, which have implications for future climate. Can applying mathematics to the research help? Dr. Emily Shuckburgh of the British Antarctic Survey, speaking at the 2012 SIAM Annual Meeting, thinks the answer is an emphatic "yes."
Scientists Uncover Diversion of Gulf Stream Path in Late 2011Woods Hole Oceanographic Institution | 15 Oct 2012
The result of his investigation was a discovery that the Gulf Stream diverged well to the north of its normal path beginning in late October 2011, causing the warmer-than-usual ocean temperatures along the New England continental shelf.
Iowa State researchers study clam shells for clues to the Atlantic's climate historyEurekAlert | 02 Oct 2012
(Iowa State University) Iowa State University's Alan Wanamaker studies the growth increments in clam shells to learn about past ocean temperatures, growing conditions and circulation patterns. Wanamaker says a better understanding of the ocean's past can help researchers understand today's climate trends and changes.
Stratosphere targets deep sea to shape climateEurekAlert | 24 Sep 2012
A University of Utah study suggests something amazing: Periodic changes in winds 15 to 30 miles high in the stratosphere influence the seas by striking a vulnerable "Achilles heel" in the North Atlantic and changing mile-deep ocean circulation patterns, which in turn affect Earth's climate.
NOAA center warns of above-average ocean temperaturesfishupdate.com | 20 Sep 2012
During the first six months of 2012, sea surface temperatures in the Northeast Shelf Large Marine Ecosystem were the highest ever recorded, according to the latest Ecosystem Advisory issued by NOAA's Northeast Fisheries Science Center (NEFSC).

New discovery of how carbon is stored in the Southern OceanEurekAlert | 30 Jul 2012
(British Antarctic Survey) A team of British and Australian scientists has discovered an important method of how carbon is drawn down from the surface of the Southern Ocean to the deep waters beneath. The Southern Ocean is an important carbon sink in the world - around 40 percent of the annual global CO2 emissions absorbed by the world's oceans enter through this region.
Tropical plankton invade Arctic watersEurekAlert | 25 Jul 2012
For the first time, scientists have identified tropical and subtropical species of marine protozoa living in the Arctic Ocean. Apparently, they traveled thousands of miles on Atlantic currents and ended up above Norway with an unusual -- but naturally cyclic -- pulse of warm water, not as a direct...
Eddies, not sunlight, spur annual bloom of tiny plants in North AtlanticEurekAlert | 06 Jul 2012
Researchers have long believed that the longer days and calmer seas of spring set off an annual bloom of plants in the North Atlantic, but University of Washington scientists and collaborators discovered that warm eddies fuel the growth three weeks before the sun does.
