Widespread seawater intrusions found beneath the grounded ice of Thwaites Glacier, West Antarctica. This makes the glacier more vulnerable to melting from a warmer ocean than anticipated, which in turn will increase projections of ice mass loss.

An iceberg named A-83, 380 sq km in size, broke off the Brunt Ice Shelf in Antarctica on May 20.

"This calving event results from a prolonged weakening of the ice at the McDonald Ice Rumples and progressive eastward extension of the so-called ‘Halloween Crack’ into the ice shelf."

In 2021, the Brunt Ice Shelf produced an iceberg called A-74 followed by an even bigger berg, named A-81, in 2023.

No showers, no privacy: What it’s really like to live in Antarctica.

CNN reports on the experiences of the few thousand humans who can say that they have lived in Antarctica.

Lake Bonney hut in the Dry Valleys of Antarctica.

My personal favorite camp on the continent. Fashioned out of a “jamesway” that was used in the Korean War. It’s a little more gritty and DIY than other camps, which gives it its charm and explains why I love it.

Satellite radar data uncover 'vigorous melting' at 's

""Thwaites is the most unstable place in the Antarctic and contains the equivalent of 60 centimeters (nearly 24") of sea level rise. The worry is that we are underestimating the speed that the glacier is changing."

Things you probably don't know about me. #1 I love antarctic science and stories. So much that I have pretty much every book written about the heroic age. I also have this. It's a picture drawn by Dr. Edward Wilson, who accompanied Scott on both his polar expeditions. This is a picture drawn by Wilson as a gift to his sister on her birthday in around 1880. I love it!

Although the is on track towards recovery, a hole over appears every year, peaking during September and October, when most biota is protected by snow and sea ice. Unfortunately, as an indirect effect of , the hole is lasting longer, until well into the summer, damaging biodiversity.

April 25 is so enjoy some Adélie penguins! ⠀


This handsome couple, two Adélie penguins (Pygoscelis adeliae), common to all the Antarctic coasts, are hand printed in black ink with a hint of orange on white Japanese kozo (or mulberry) paper. Each print is 12.5” x 9.25” (31.8 cm x 23.5cm). Adélie penguins are the most widely spread and southernly penguins (along with the Emperor penguins).⠀

Bids still only at $6000 for "Hansel" the Antarctic Hagglund

ai6yr, to random

Bids only at $1250 so far! It's the cheapest Antarctic Hagglund you'll find in Ventura County.

It's a really good thing I don't have room or money (or need) for this... 1986 Hagglund up for auction down the street. "Hansel". Picture from below at McMurdo Station is the sister of Hansel, "Gretel", somewhere roaming around Antarctica.

Pallets upon pallets of Antarctic expedition gear. I believe some Hollywood prop house bought these last time.

261 authors from 152 institutions in 22 countries on 6 continents. And that is a small part-of-the NISP-instrument paper in the @ec_euclid. 🤪

To be submitted tomorrow. The main instrument paper will follow in ~2 weeks.

Will both (and more!) appear on arXiv on 24 May 🙂

And do you know what this means? It means we urgently need collaborators in !

‘Simply mind-boggling’: world record temperature jump in Antarctic raises fears of catastrophe (www.theguardian.com)

An unprecedented leap of 38.5C in the coldest place on Earth is a harbinger of a disaster for humans and the local ecosystem...Poleward winds, which previously made few inroads into the atmosphere above Antarctica, are now carrying more and more warm, moist air from lower latitudes – including Australia – deep into the...

"There is now a real danger that some significant will occur in the next few decades as the ice sheets and glaciers of west continue to shrink. These are being eroded at their bases by warming ocean water and could disintegrate in a few decades."
