Arctic sea ice maximum, March 6, 2023 Animation of arctic sea ice from the September 18, 2022 minimum to the the March 6, 2023 maximum

Arctic Sea Ice Minimum 2022, Animation Arctic Sea Ice Minimum 2022, Print Resolution Still Satellite-based passive microwave images of the sea ice have provided a reliable tool for continuously monitoring changes in the Arctic ice since 1979. Every summer the Arctic ice cap melts down to what scientists call its "minimum" before colder weather begins to cause ice cover to increase. An analysis of satellite data by NASA and the National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder shows that the 2021 minimum extent, which was likely reached on Sept. 18, measured 1.80 million square miles (4.67 million square kilometers).The Japan Aerospace Exploration Agency (JAXA) provides many water-related products derived from data acquired by the Advanced Microwave Scanning Radiometer 2 (AMSR2) instrument aboard the Global Change Observation Mission 1st-Water "SHIZUKU" (GCOM-W1) satellite. Two JAXA datasets used in this animation are the 10-km daily sea ice concentration and the 10 km daily 89 GHz Brightness Temperature.In this animation, the daily Arctic sea ice and seasonal land cover change progress through time, from the yearly maximum ice extent on February 25 2022, through its minimum on September 18 2022. Over the water, Arctic sea ice changes from day to day showing a running 3-day minimum sea ice concentration in the region where the concentration is greater than 15%. The blueish white color of the sea ice is derived from a 3-day running minimum of the AMSR2 89 GHz brightness temperature. The yellow boundary shows the minimum extent averaged over the 30-year period from 1981 to 2010. Over the terrain, monthly data from the seasonal Blue Marble Next Generation fades slowly from month to month. Related pages

Arctic sea ice maximum, February 25, 2022 Animation of arctic sea ice from the September 16, 2021 minimum to the the February 25, 2022 maximum After growing through the fall and winter, sea ice in the Arctic appears to have reached its annual maximum extent. The image above shows the ice extent—defined as the total area in which the ice concentration is at least 15 percent—at its 2022 maximum, which occurred on February 25, tying with 2015 for the third earliest maximum on record. On this day the extent of the Arctic sea ice cover peaked at 14.88 million square kilometers (5.75 million square miles), making it the tenth lowest yearly maximum extent on record. Related pages

Every summer the Arctic ice cap melts down to what scientists call its "minimum" before colder weather begins to cause ice cover to increase. The extent of Arctic sea ice at the end of this summer was the second lowest since satellite monitoring began. An analysis of satellite data by NASA and the National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder shows that the 2020 minimum extent, which was likely reached on Sept. 15, measured 1.44 million square miles (3.74 million square kilometers).The Japan Aerospace Exploration Agency (JAXA) provides many water-related products derived from data acquired by the Advanced Microwave Scanning Radiometer 2 (AMSR2) instrument aboard the Global Change Observation Mission 1st-Water "SHIZUKU" (GCOM-W1) satellite.
