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

Researchers from the Alfred Wegener Institute traveled to the Arctic Sea to study the effects of climate change, and they say ...

For years, scientists have debated whether a giant thick ice shelf once covered the entire Arctic Ocean during the coldest ...

A report from a European news wire agency on the reversal of an important ocean current has sparked alarm online.

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

Summer sea ice in the Arctic Ocean might be gone by the 2030s, no matter what we do to curb emissions of greenhouse gases, study says.

A study has highlighted the devastating effects that the warming waters of the Arctic Ocean are having on carbon emissions.

Harmful algae blooms have been rapidly producing in a place previously too cold to host the toxin: the Arctic.

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, paired ...

The first ice-free days of the Arctic Ocean could occur as soon as the 2020s or 2030s — as many as 10 years earlier than previous projections.

For thousands of years the Arctic Ocean remained covered by an enormous ice sheet almost a kilometre thick, effectively cutting off routes to other bodies of water and resulting in the ocean ...

According to scientists, Arctic waters typically contain layers of water with different temperatures, salinity and densities, all of which impact the formation of sea ice and how long that ice lasts.
