Ancient Antarctic ice sheet cycles affected subtropical ocean productivity by altering nutrient circulation. The 40,000-year obliquity cycle played an unexpectedly strong role, revealing deep global ...

A research team developed a satellite-based method to analyze the life cycle of ocean eddies forming along Arctic sea-ice edges. By combining sequential synthetic aperture radar (SAR) images with ...

This research shows how close examination of even microscopic fossils can reveal large-scale patterns such as ocean ...

One of the ocean currents in the Arctic Ocean is at risk of disappearing this century because of climate change, according to a new joint study from the University of Gothenburg and the German Alfred ...

UW–Madison researchers show a 40,000-year obliquity cycle in Antarctic ice growth altered Southern Ocean nutrients, boosting ...

The global ocean “conveyor belt” circulation, shown in part here as red and blue lines, circulates cooler seawater below the surface and warmer seawater at the surface throughout the world’s oceans.

Since 2016, Antarctic sea ice extent has been declining sharply – now scientists are piecing together how strong winds and ...

For more than a century, a patch of cold water south of Greenland has resisted the Atlantic Ocean's overall warming, fueling debate among scientists. A new study identifies the cause as the long-term ...
