Antarctic sea ice extent, a measure of the ocean area in the southern hemisphere that is at least 15% sea ice, was historically low in 2023 (Axios). The question will be suspended on 10 October 2024 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 11 October 2024 (Charctic Interactive Sea Ice Graph, click "Antarctic" on the left side above the graph, About Charctic Data). Other site data is immaterial. As of the launch of this question, the highest daily reported Antarctic sea ice extent in 2023 was 16.956 million sq. km on 10 September.
