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 #Arctic and #Antarctica measuring thermal infrared radiation — the same type of energy emitted from a heat lamp — that will make #climate models more accurate and help predict changes caused by #GlobalWarming," 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.
The Halley VIa Research Station operated by the British Antarctic Survey (BAS) is located on the Brunt Ice Shelf as shown in the map below. It used to sit on the A-81 iceberg area as seen in the map above and was moved to its current location in 2016 before A-81 broke loose.
BAS notes that this A-83 calving was expected, the ice shelf is stable and they don’t expect a response to this new event.
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.
The #observatory monitors temperature, water depth, oxygen & chlorophyll levels in the #ocean water. Paired to a #satellite, the observatory transmits #data every 30 mins to #researchers.
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
