Derived from NSIDC’s Charctic Interactive Sea Ice Graph, this graph shows daily Antarctic sea ice extent—the area of the Southern Ocean with at least 15 percent sea ice concentration—across the satellite record from 1979-2023. Ice extent in 2023 (bright blue) was slightly smaller than the previous record low (2022, shown in magenta) at the summer minimum in February, but much smaller in late June, the start of the winter ice growth season. All other years in the satellite record (1979–2021) are light gray-blue. Graph by NOAA Climate.gov/NSIDC.
