Last month observed widespread warmer than average sea surface temperatures surrounding the #Arctic Ocean ice edge. Some of the largest anomalies were along the coast in the southeastern Barents Sea.

Polar stereographic map showing sea surface temperature anomalies in January 2025 relative to 1982 to 2010. Most areas are warmer than average. Sea-ice cover is also shown if sea-ice concentration is at least 15% per each grid point. Red is shown for warmer sea surface temperatures, and blue is shown for colder sea surface temperatures. Data is from OISSTv2.1.

Optimum Interpolation Sea Surface Temperature (OISST)

The NOAA 1/4° Daily Optimum Interpolation Sea Surface Temperature (OISST) is a long term Climate Data Record that incorporates observations from different platforms (satellites, ships, buoys and Argo floats) into a regular global grid.
