A study published Monday in the Proceedings of the National Academy of Sciences found that increases in salinity in seawater ...

Including the effects of evolving subglacial water in ice sheet models can triple the amount of ice flowing to the ocean. This adds more than two meters to global sea levels by 2300, with ...

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 ...

New research reveals Antarctic sea ice has hit record lows three times since 2017, creating cascading effects on global ...

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

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

On her first dedicated scientific voyage to Antarctica in March, the Australian icebreaker RSV Nuyina found the area sea-ice ...

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

In 2017, Alf Norkko, a professor of marine research at the University of Helsinki, and his team discovered big changes on the seafloor under Antarctic sea ice since their previous diving ...
