Sea Ice Today - National Snow and Ice Data Center
Nov 4, 2024 · Sea ice data is updated daily, with a one-day lag. On occasion, there is data delay which is usually resolved within a few days. The orange line in extent and concentration images (left and middle) and the gray line in the time series (right) indicate 1981 to 2010 average extent for the day shown.

The new abnormal | National Snow and Ice Data Center
Oct 3, 2024 · Since 2007, the Arctic sea ice minimum has dropped below 5 million square kilometers (1.93 million square miles) every year, except in 2009, 2013, and 2014, when extent barely crossed the 5 million square kilometer mark. Such low extents would have been hard to imagine in the 1990s, when extent averaged 6.46 million …
Sea Ice Index, Version 3 | National Snow and Ice Data Center
The Sea Ice Index provides a quick look at Arctic- and Antarctic-wide changes in sea ice. It is a source for consistent, up-to-date sea ice extent and concentration images, in PNG format, and data values, in GeoTIFF and ASCII text files, from November 1978 to the present.

Search for and download NSIDC DAAC data using the earthaccess python package. This python-based Jupyter notebook also demonstrates geospatial operations to crop and resample one GeoTIFF based on the extent and pixel size of another GeoTIFF, with the end goal of plotting one on top of the other.
Arctic sea ice extent levels off; 2024 minimum set
Sep 24, 2024 · On September 11, Arctic sea ice likely reached its annual minimum extent of 4.28 million square kilometers (1.65 million square miles). The 2024 minimum is the seventh lowest in the nearly 46-year satellite record. The last 18 years, from 2007 to 2024, are the lowest 18 sea ice extents in the satellite record.
