A large iceberg broke off the deteriorating Thwaites glacier and, along with sea ice, it is blocking two research ships with dozens of scientists from examining how fast its crucial ice shelf is falling apart.
This photo provided by environmental scientist David Holland shows tents set up on the Dotson Ice Shelf in Antarctica on Monday, Jan. 31, 2022. A large iceberg broke off the deteriorating Thwaites glacier and along with sea ice it is blocking two research ships with dozens of scientists from examining how fast its crucial ice shelf is falling apart. The smaller Dotson ice shelf is about 87 miles west of the Thwaites ice shelf.
New York University environmental scientist David Holland, who planned to drill deep through the Thwaites ice shelf to measure the water's warmth below it, is achingly close but not quite there. Much of the problem is that loads of sea ice have gravitated around the huge iceberg. And that's ironic — and troublesome for researchers — because overall Antarctic sea ice is unusually low for this time of year, Larter said.
“I think the ice shelf will be gone in a matter of years to decades,” Holland said via Zoom on a computer set up on an outdoor table in the 24-hour sun, where the morning temperature was -4 . “But the actual inland ice, that’s the really unknown question.”
