Most walruses (Odobenus rosmarus) live near the Arctic Circle, where they hunt for shellfish in shallow water and clamber up onto the icebergs and beaches to rest, Live Science previously reported. The humongous creatures rarely crop up along the Irish shoreline. The first recorded walrus sighting there occurred in 1897, but no other walruses were seen until the 1980s, the Irish public service broadcaster RTE reported. Since then, fewer than two dozen additional walruses have been spotted in Ireland.
The ocean north of Antarctica has turned into an "alphabet soup" of broken icebergs, according to a new blog post on NASA's Earth Observatory website. In a satellite photo snapped on Feb. 11, 2021, the jagged outlines of 11 fractured icebergs swirl around a remote, penguin-filled island called South Georgia, located about 940 miles (1,500 kilometers) northeast of the Antarctic Peninsula. Each frozen chunk is a piece of the once-mighty iceberg A-68a, which held the title of world's largest iceberg for more than three years before Shattering into a dozen pieces a few weeks ago. Now, each broken bit of the puzzle has its own name, beginning with A-68b, and ending with A-68M. (Several of the icebergs are not visible in this photo.)
