Ocean Currents (Page 3)
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.
US research vessel winds down visit to Vietnam as part of joint oceanographic research programEurekAlert | 28 Jun 2012
U.S. scientists and Vietnamese researchers will discuss coastal ocean circulation and land-ocean environmental trends this week as the R/V Roger Revelle, an auxiliary general purpose oceanographic research vessel, continues its nine-day port call in the city of Da Nang. Owned by the Office of Naval Research and operated by the Scripps Institution of Oceanography, the vessel arrived in Vietnam June 22.
A Refuge for Corals?Woods Hole Oceanographic Institution | 02 May 2012
In a warming world, study finds coral reefs may have a safe haven in the equatorial Pacific.
A New View of the Aqueous GlobeNew York Times | 02 May 2012
A moving map of the oceans' currents will allow scientists to better understand how currents shift heat and carbon around the globe, underlying the dynamics of climate change.
Pacific islands may become refuge for corals in a warming climate, study findsEurekAlert | 30 Apr 2012
Scientists have predicted that ocean temperatures will rise in the equatorial Pacific by the end of the century, wreaking havoc on coral reef ecosystems. But a new study by Woods Hole Oceanographic Institution scientists shows that climate change could cause ocean currents to operate in a surprising way and mitigate the warming near a handful of islands right on the equator. As a result these Pacific islands may become isolated refuges for corals and fish.
Global ocean drifter deployed off of South FloridaNOAA | 29 Apr 2012
In celebration of Earth Day, three area students deployed a National Oceanic and Atmospheric Administration (NOAA) ocean drifter on April 27, contributing to a global array that yields vital environmental data.
Warm ocean currents cause majority of ice loss from AntarcticaEurekAlert | 26 Apr 2012
Reporting this week, Thursday 26 April, in the journal Nature, an international team of scientists led by British Antarctic Survey has established that warm ocean currents are the dominant cause of recent ice loss from Antarctica.
Local students deploy global ocean drifter off of MassachusettsNOAA | 17 Apr 2012
Getting an early jump on Earth Day, students from several Boston-area schools helped ready and deploy a National Oceanic and Atmospheric Administration (NOAA) ocean drifter today, contributing to a global array that yields vital environmental data.
Oceanus : A Newfound Cog in the Ocean ConveyorWoods Hole Oceanographic Institution | 29 Mar 2012
A decade into the 21st century, scientists have confirmed the existence of a new and apparently crucial ocean current on the face of the Earth. International teams led by Woods Hole Oceanographic Institution (WHOI) oceanographer Bob Pickart verified the previously unknown current near Iceland in 2008 and returned in 2011 to determine how it is formed.
Powerful Currents in Deep-Sea GorgesWoods Hole Oceanographic Institution | 12 Mar 2012
I research the way the shape of the ocean floor affects the oceans circulation. More particularly, I explore the fundamental physics that transforms energy, drives currents, and mixes up water masses in the deep ocean. It turns out that features of the undersea landscape might play a big and previously unknown role.
MIT research: Sometimes the quickest path is not a straight lineEurekAlert | 08 Mar 2012
A team, led by Pierre Lermusiaux, the Doherty Associate Professor in Ocean Utilization, developed a mathematical procedure that can optimize path planning for automated underwater vehicles, even in regions with complex shorelines and strong shifting currents.
Declining silicate concentrations in the Norwegian and Barents SeasOxford Journals | 16 Feb 2012
Since 1990, a decline in silicate concentrations together with increasing salinities has been observed in the Atlantic water of the Norwegian and Barents Seas. This decline in silicate has been found to be related to the relative proportion in which eastern and western source water masses from the northeastern North Atlantic enter the Norwegian Sea.
