New research challenges the long-held belief that the Arctic Ocean was covered by a massive ice shelf during ice ages.

Even during the coldest 750,000 years, the Arctic Ocean had open water and sustained life thanks to seasonal sea ice. “Our ...

A recent study is shedding light on the ongoing accumulation of mercury pollution in the Arctic — despite the international ...

Ice loss in Antarctica and its impact on the planet—sea level rise, changes to ocean currents and disturbance of wildlife and ...

"Transport of mercury from major sources like China to Greenland via ocean currents can take up to 150 years," says Rune Dietz. "This helps explain the lack of decline in Arctic mercury levels." ...

Large sea anchors could be used to drag water under a bold plan to keep the Atlantic Meridional Overturning Circulation ...

The in-depth analysis reveals how local tidal currents strongly affect the movement of sea ice in the Arctic ocean and provides an unprecedented look at how the makeup of the seafloor is causing ...

Now, new research has found that Arctic Ocean sea ice is shrinking even faster than previously thought — and that the Arctic may start to see its first “ice-free” days within the current decade.

In the last few decades, the Arctic sea ice has receded ever further, including increasingly in winter when the extent of sea ...

Summer sea ice in the Arctic Ocean might be a thing of the past by the 2030s, no matter what we do to curb emissions of the greenhouse gases that cause global warming, an international study ...

New research suggests continued global warming could put a major Arctic ocean current in serious trouble, and that the consequences could extend far beyond the North. Known as the Beaufort Gyre ...
