Arctic sea ice extent tracked at near-record low levels through much of June, hitting daily record low levels from June 20 to 26. Sea ice coverage was particularly low in the Barents and Kara Seas, Hudson Bay, and Baffin Bay. There have been unrecoverable gaps in the delivery of sea ice data from the Defense Meteorological Satellite Program (DMSP) Special Sensor Microwave Imager/Sounder (SSMI/S) source data. Moreover, NSIDC has been informed that the SSMIS data feed will be ending July 31. We are preparing to switch to the Japan Aerospace Exploration Agency (JAXA) Advanced Microwave Scanning Radiometer-2 (AMSR2) passive microwave sensor as the primary data source.

With budget cuts from NASA for Sea Ice Today, we will no longer write mid-month analyses in the months leading up to the Arctic sea ice minimum.
