Declining silicate concentrations in the Norwegian and Barents Seas
Oxford 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.

Huge pool of Arctic water could cool Europe: study
Reuters | 22 Jan 2012
LONDON (Reuters) - A huge pool of fresh water in the Arctic Ocean is expanding and could lower the temperature of Europe by causing an ocean current to slow down, British scientists said Sunday.

Louis St. Laurent receives Nicholas P. Fofonoff Award from AMS
EurekAlert | 19 Jan 2012
Louis St. Laurent of the Woods Hole Oceanographic Institution was selected by the American Meteorological Society to receive the prestigious Nicholas P. Fofonoff Award. There will be a formal presentation at the Annual Awards Banquet on Jan. 25, 2012, at the AMS annual meeting in New Orleans, La.

Variability of North Atlantic heat transport observed from instrument data
American Geophysical Union | 16 Jan 2012
The Atlantic meridional overturning circulation (AMOC), which transports warm water northward and cold water back southward, redistributes energy throughout the North Atlantic Ocean. Some models predict that AMOC will slow down as Earth's temperatures rise due to anthropogenic warming, which could...

UCSB scientists say topography played key role in Deepwater Horizon disaster
EurekAlert | 09 Jan 2012
(University of California - Santa Barbara) When UC Santa Barbara geochemist David Valentine and colleagues published a study in early 2011 documenting how bacteria blooms had consumed almost all of the deepwater methane plumes following the Deepwater Horizon oil spill in 2010, some people were skeptical. How, they asked, could almost all of the lethal gas emitted from the Deepwater Horizon well just disappear?

Multi-year prediction of Atlantic Meridional Overturning Circulation at 26.5 °N possible
ScienceDaily.com | 06 Jan 2012
Climate scientists have now shown for the first time that the strength of the Atlantic Meridional Overturning Circulation at 26.5 N can be skillfully predicted for up to four years.

Russian river water unexpected culprit behind Arctic freshening near US, Canada
EurekAlert | 04 Jan 2012
(University of Washington) A hemisphere-wide phenomenon -- and not just regional forces -- has caused record-breaking amounts of freshwater to accumulate in the Arctic's Beaufort Sea.

Russian runoff freshening Canadian Arctic, NASA finds
ScienceDaily.com | 04 Jan 2012
A new study allays concerns that melting Arctic sea ice could be increasing the amount of freshwater in the Arctic enough to have an impact on the global "ocean conveyor belt" that redistributes heat around our planet. Researchers detected a previously unknown redistribution of freshwater during...

Russian ship finds tsunami debris where scientists predicted
EurekAlert | 17 Oct 2011
Ever since the Japan tsunami on March 11 washed millions of tons of debris into the Pacific, scientists at the University of Hawaii Manoa have been looking for evidence to validate their computer model of the trajectory of these debris that are endangering small ships and coastlines.

Newly discovered Icelandic current could change climate picture
EurekAlert | 24 Aug 2011
(National Science Foundation) If you'd like to cool off fast in hot summer weather, take a dip in a newly discovered ocean current called the North Icelandic Jet (NIJ).

Newly discovered Icelandic current could change North Atlantic climate picture
EurekAlert | 22 Aug 2011
An international team of researchers, including physical oceanographers from the Woods Hole Oceanographic Institution, has confirmed the presence of a deep-reaching ocean circulation system off Iceland that could significantly influence the ocean's response to climate change in previously unforeseen ways.

New Iceland current could sway N. Atlantic climate
Reuters | 21 Aug 2011
WASHINGTON (Reuters) - A newly discovered deep, cold current flowing off Iceland's coast may reveal that the North Atlantic is less sensitive to climate change than previously thought, researchers reported Sunday.

Ocean currents speed melting of Antarctic ice
EurekAlert | 27 Jun 2011
(The Earth Institute at Columbia University) Stronger ocean currents beneath West Antarctica's Pine Island Glacier Ice Shelf are eroding the ice from below, speeding the melting of the glacier as a whole, according to a new study in Nature Geoscience.

Atmospheric carbon dioxide buildup unlikely to spark abrupt climate change, scientists find
ScienceDaily.com | 21 Jun 2011
New research lends support to recent studies that suggest abrupt climate change is the result of alterations in ocean circulation uniquely associated with ice ages, not from atmospheric carbon dioxide.

Ice sheet collapse affects ocean circulation
American Geophysical Union | 01 Jun 2011
As Earth's climate warms and ice melts, freshwater input to oceans could weaken the large-scale Atlantic meridional overturning circulation, which acts as an important conveyor of heat and has significant effects on climate.

Long reach of the deep sea: Oceanographers document effect of equatorial deep currents on West Afric...
ScienceDaily.com | 19 May 2011
Our climate is affected by the ocean in many ways. The most prominent example is the El Niño phenomenon in the Pacific, a well-documented interannual climate signal. Oceanographers from Germany and the United States have recently documented the effect of deep equatorial currents in the Atlantic on rainfall and climate over West Africa.
