Interesting, Antarctica has a Level 2 "Exercise Increased Caution" advisory from the U.S. State Department. (and has for awhile?)

"Exercise increased caution in Antarctica due to environmental hazards posed by extreme and unpredictable weather and limited emergency services."


@ai6yr I sailed to the Antarctic Peninsula a half-dozen times with a scientist I was working for as a project engineer a while back. Almost every time there was some kind of medical emergency that required us to detour to a nearby outpost for a medical evacuation flight. One time, the fog was so thick everywhere that we had to transport the patient all the way back to South America. It is incredibly difficult to get back to civilization from most parts of Antarctica. #Antarctica

"On May 20th, 2024, an measuring 380 square kilometers (~147 mi2) broke off the Brunt Ice Shelf in .

The ongoing loss of Antarctic ice is one of the clearest indications of rising global temperatures and a dire warning."

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. Paper:

At the poles, more heat radiates out into space than is absorbed from the sun.

Rocket Lab launches NASA cubesat to study heat lost from Earth's poles

"The PREFIRE duo "will criss-cross over the and measuring thermal infrared radiation — the same type of energy emitted from a heat lamp — that will make models more accurate and help predict changes caused by ," Rocket Lab wrote in a mission description."

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.

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! #antarctica #captainscott

...the world’s widest glacier and roughly the size of Florida.
It’s also Antarctica’s most vulnerable and unstable glacier, in large part because the land on which it sits slopes downward, allowing ocean waters to eat away at its ice."
