The lowest Antarctic sea ice extent on record and glacier mass loss in parts of the Arctic are just two examples marking the continued impacts of record levels of heat-trapping greenhouse gases in ...

It has been a record warm summer here at 80 degrees north of Svalbard in the Arctic Ocean. Enhanced melting of sea-ice can significantly change ocean circulation, causing lower temperatures across ...

Snugged up against the upper edges of the Canadian Arctic Archipelago and Greenland lies the oldest and thickest sea ice in the world, covering hundreds of thousands of square kilometres of ocean.

Researchers used more than 300 computer models to predict when the Arctic Ocean could have its first ice-free day. In a worst-case scenario, that could happen in 2027.

A diver goes into the cold waters of the Arctic Ocean during Operation Nanook-Nunalivut in February 2022. They dove to a depth of up to 21 meters, through a hole cut into ice 1.5 metres thick.

Warm Atlantic waters are rapidly reshaping the Siberian Arctic, sparking an era of unprecedented sea ice loss—something that will have ongoing implications for the region’s ecosystem and ...

At the center of Greenland, where the planet’s largest ice sheet pours down into the Arctic air, a weather station recently ...

For decades, scientists believed the Arctic Ocean was sealed under a massive slab of ice during the coldest ice ages — but new research proves otherwise. Sediment samples from the seafloor ...

Researchers at the University of Toronto have identified the mechanism responsible for the formation of temperature and salinity “staircases” in the Arctic Ocean, resolving a mystery that has ...

The exception has been the Arctic Ocean, which has seen a sharp rise in POPs in its frigid waters over the past several decades. In a paper published in the journal Science Advances, Concordia ...
