After the 2 days of storm, the surface has been scoured into crazy sastrugi patterns at our field site this afternoon.

It's a beautiful day after the storm, spent a morning in the lab preparing samples for oxygen isotopes, but we're going out later for more coring and sampling. Here are WP9 including @mercerraa@pixelfed.global heading out for a few days overnight on the shelf.
The small cabins give a useful sense of scale in the huge landscape.

The same glacier view under a blue sky with two scooters pulling a cabin and a sled at the bottom.
A large blue container with communication mast is on top of a snow covered slope, a small blue cabin pulled by a snow scooter is descending the slope under a deep blue sky

"On the Antarctic Peninsula, the area of ice-free 'greening' has jumped from 86 hectares to nearly 1200 over four decades - the size of a large sheep and beef farm, now exposed land rather than ice."

A shame they didn't say over what period of time. But a 2024 Nature article says;
"The area of likely vegetation cover increased from 0.863 km2 in 1986 to 11.947 km2 in 2021."

The #DoomsdayGlacier Is Getting Closer and Closer to Irreversible Collapse
An analysis of the expansion of cracks in the #ThwaitesGlacier over the past 20 years suggests that a total collapse could be only a matter of time.
by Ritsuko Kawai, Dec 22, 2025 9:43 AM
Excerpt: "Known as the ' #Doomsday Glacier,' the Thwaites Glacier in #Antarctica is one of the most rapidly changing glaciers on Earth, and its future evolution is one of the biggest unknowns when it comes to predicting global sea level rise.
"The eastern ice shelf of the Thwaites Glacier is supported at its northern end by a ridge of the ocean floor. However, over the past two decades, cracks in the upper reaches of the glacier have increased rapidly, weakening its structural stability. A new study by the International Thwaites Glacier Collaboration (ITGC) presents a detailed record of this gradual collapse process.
"Researchers at the Centre for Earth Observation and Science at the University of Manitoba, Canada, analyzed observational data from 2002 to 2022 to track the formation and propagation of cracks in the ice shelf shear zone. They discovered that as the cracks grew, the connection between the ice shelf and the mid-ocean ridge weakened, accelerating the upstream flow of ice."

Antarctica completely collapsed 9,000 years ago under similar climate conditions as Earth has today
About 9,000 years ago, part of Antarctica’s eastern ice sheet collapsed astonishingly fast, driven by warmer ocean water. The study focuses on the East Antarctic Ice Sheet, a vast body of land ice in East Antarctica

Check out the recent "warmth" over #Antarctica! Maps show temperature anomalies over the last month (left), 3 months (center), and 12 months (right) across the Southern Hemisphere. Red areas denote warmer than average temperatures and blue areas colder than average.

Krill harvesting threatens whale recovery 🐋
Soaring human demand for #krill in the #SouthernOcean poses a challenge to the recovery of #whale species once hunted nearly to extinction. #Stanford researchers identify the growing food conflict and offer solutions.
Overlap between industrial krill fishing and foraging whales, such as the humpback whale pictured here, may threaten #BaleenWhale recovery around #Antarctica.
