The University of Bergen A new study looking at past climate change, asks if these changes in the future will be spasmodic and abrupt rather than a more gradual increase in the temperature Today, deep waters formed in the northern North Atlantic fill approximately half of the deep ocean globally. In the process, this impacts on the circum-Atlantic climate, regional sea level, and soak up much of the excess atmospheric carbon dioxide from industrialization — helping to moderate the...

U.S. scientists say they have discovered a new pathway for the global ocean circulation known as the Great Ocean Conveyor. Researchers from the Woods Hole Oceanographic Institution and Duke University said the conveyor belt paradigm says the Gulf Stream-warmed ocean releases heat to the atmosphere in the northern North Atlantic, leaving ocean water colder and denser as it moves north. The cold waters then sink and flow southward along the deep western boundary current that hugs the...

A study reported in yesterday's issue of Nature disputes a longstanding picture of how ice sheets influence ocean circulation during glacial periods. The distribution of sunlight, rather than the size of North American ice sheets, is the key variable in changes in the North Atlantic deep-water formation during the last four glacial cycles, according to the article. The new study goes back 425,000 years, according to Lorraine Lisiecki, first author and assistant professor in the Department of...
