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

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

New research has, for the first time, tracked ice shelf, sea ice and ocean swell wave conditions over multiple years in the ...

In 2022, an international team of scientists sent a 20-foot-long autonomous underwater vehicle (AUV) named “Ran” to traverse ...

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 ...

More than 40% of Antarctica’s ice shelves have shrunk over the past 25 years, a study published Thursday found, as scientists warn they’re losing volume with no sign of recovery because of the ...

Ice shelves are the part of ice sheets — a form of glacier — that float over water. Three of those shelves in North Greenland have "completely" collapsed, researchers said, ...

Ice shelves’ net gain of 661 gigatonnes of ice mass between 2009 and 2019 does not negate the net loss, opens new tab of 2,440 gigatonnes of ice mass between 2002 and 2024.

Shelf ice along the Lake Michigan shoreline can be seen from the Portage Lakefront Park, but park officials have roped off walkways leading to that ice because of its danger.
