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

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 ...

We present a methodology to derive sea ice type classification maps in the Atlantic sector of the Arctic Ocean for the autumn through spring seasons, from 1991 to present. We use datasets from four ...

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

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