Annual Sea Ice Cycle over Northern Canada

Animation of Maximum to Minimum Arctic Sea Ice Extent, 2018, with 30-Year Average Animation of Maximum to Minimum Sea Ice Extent, 2018 Animation of Maximum to Minimum Sea Ice Extent, 2018, No Dates Dates Only Print-Resolution Still Image of 2018 Arctic Sea Ice Minimum Extent, With 30-Year Average Print-Resolution Still Image of 2018 Arctic Sea Ice Minimum Print-Resolution Still Image of 2018 Arctic Sea Ice Minimum Extent, With 30-Year Average, No Labels Print-Resolution Still Image of 2018 Arctic Sea Ice Minimum, No Labels 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 March 17, 2018 through September 23, 2018, when the ice reaches its annual minimum extent. 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 colour of the sea ice is derived from a 3-day running minimum of the AMSR2 89 GHz brightness temperature. Over the land, monthly data from the seasonal Blue Marble Next Generation fades slowly from month to month. Related pages

This is below the previous lowest maximum recorded in 2015 when it reached 14.54 million square kilometers (5.612 million square miles). Overall, there is a declining trend in the maximum extent of about 2.8 % per decade. This is much smaller than the summer trends, but also reflects the long-term warming trend in the Arctic.While a low maximum gives the extent a head start heading into summer, it turns out that there is not much relation between the maximum and summer minimum and a record low maximum does not portend a record low minimum. This is because the ice near the edge at the time of the maximum is thin, seasonal ice that will melt out early in the summer. The weather conditions in the Arctic during the summer melt season is the most crucial in determining whether a record low is possible in any given year.In this animation, the Arctic sea ice area is derived from a running 3-day maximum of the AMSR2 sea ice concentration 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 that is linearly mapped between the high and low values. Related pages
