Ocean Currents
Kiwi scientists set sail for Antarctic expeditionNew Zealand Herald | 03 Feb 2013An 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.
Southern Ocean | Ocean Currents | Research 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.
Ocean Currents | Research Tracing the origin of Arctic driftwoodonlinelibrary.wiley.com | 29 Jan 2013Driftwood 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.
Arctic Ocean | Ocean Currents | Research Mathematics and the ocean: Movement, mixing and climate modelingEurekAlert | 18 Oct 2012Studying 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."
Climate Change | Ocean Currents Stratosphere targets deep sea to shape climateEurekAlert | 24 Sep 2012A 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.
Atlantic Ocean | Ocean Currents 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.
Southern Ocean | Ocean Currents | Research Tropical plankton invade Arctic watersEurekAlert | 25 Jul 2012For 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...
