Beginning October 15, 2025, NSIDC’s Sea Ice Today services will be reduced because of non-renewed funding. This means no new monthly and mid-month analysis posts ...
On September 17, Antarctic sea ice likely reached its annual maximum extent of 17.81 million square kilometers (6.88 million square miles). The 2025 maximum is the third lowest in the 47-year ...
Antarctic sea ice has likely reached its maximum extent for the year, at 17.81 million square kilometers (6.88 million square miles) on September 17, according to scientists at the National Snow and ...
On September 10, Arctic sea ice likely reached its annual minimum extent of 4.60 million square kilometers (1.78 million square miles). The 2025 minimum shares the tenth lowest spot in the nearly ...
Throughout August 2025, sea ice rapidly melted and compacted north of Alaska in the Beaufort Sea, initiated by a warm pulse of air from east Siberia that was sustained by persistent winds from the ...
At the end of July 2025, daily sea ice extent in both hemispheres ranked third lowest in the 47-year satellite record. For most of the month, Arctic sea ice extent tracked close to levels recorded for ...

These data sets provide daily files of brightness temperature data and sea ice concentrations for both the Northern and Southern Hemispheres. These data products serve as a replacement for the ...
Update: DMSP SSMIS data processing has been extended through 31 July 2025. See the Earthdata: Status Update on DMSP Data Products for further details. The NASA National Snow and Ice Data Center ...
Arctic sea ice extent in May declined at a slightly faster pace compared to average. In Antarctica, the Bellingshausen Sea remains nearly ice free as far south as 72 degrees South by the end of May.
Arctic sea ice extent through most of April changed very little. Only at the end of the month did extent begin to decline. Because the month started with unusually low extent, however, the average ...
