What will be the lowest reported Antarctic sea ice extent in 2025 as of 12 March 2025?
Closing Mar 12, 2025 07:01AM UTC
Antarctic sea ice extent, a measure of the ocean area in the southern hemisphere that is at least 15% sea ice, reached near historic lows in 2024 (NASA Earth Observatory). The question will be suspended on 11 March 2025 and the outcome determined using graph data as provided by the National Snow & Ice Data Center's (NSIDC's) "Charctic Interactive Sea Ice Graph" at approximately 5:00PM ET on 12 March 2025 (Charctic Interactive Sea Ice Graph, click "Antarctic" on the left side above the graph, About Charctic Data). The question will close as of the date of the lowest reported Antarctic sea ice extent (the most recent if there is a tie for the lowest extent). Other site data is immaterial. As of the launch of this question, the lowest daily reported Antarctic sea ice extent in 2024 was 1.985 million sq. km on 20 February.
