An animation of the Arctic sea ice from September 7th, 2015 through March 24th, 2016 with dates
This video is also available on our YouTube channel.
The maximum Arctic sea ice extent appears to have occurred on March 24, 2016, reaching an extent of 14.52 million square kilometers (5.607 million square miles). 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.

AMSR-E Arctic Sea Ice Yearly Maximum from 2003 through 2009
Read moreSea ice is frozen seawater floating on the surface of the ocean, typically averaging a few meters in thickness. Some sea ice is semi-permanent, persisting from year to year, and some is seasonal, melting and refreezing from season to season. The sea ice cover reaches its maximum extent at the end of each winter, generally in February or March. This series of images of the yearly sea ice maximum extent depicts data from the AMSR-E instrument on the Aqua satellite. The false color in these images of sea ice is derived from the daily AMSR-E 6.25 km 89 GHz brightness temperature while the sea ice extent is derived from the daily AMSR-E 12.5 km sea ice concentration. ||

Loop of AMSR-E Daily Arctic Sea Ice from Aug 2005 to Aug 2006
Read moreSea ice is frozen seawater floating on the surface of the ocean. Some sea ice is permanent, persisting from year to year, and some is seasonal, melting and refreezing from season to season. Sea ice is almost always in motion, reacting to ocean currents and to winds. The AMSR-E instrument on the Aqua satellite acquires high resolution measurements of the 89 GHz brightness temperature near the poles. Because this is a passive microwave sensor and independent of atmospheric effects, this sensor is able to observe the entire polar region every day, even through clouds and snowfalls. This animation of AMSR-E 89 GHz brightness temperature in the northern hemisphere during late 2005 and early 2006 clearly shows the dynamic motion of the ice as well as its seasonal expansion and contraction. This animation shows the seasonal advance and retreat of sea ice over the Arctic from 8/5/2005 through 8/4/2006. The false color of the sea ice, derived from the AMSR-E 6.25 km 89 GHz brightness temperature, highlights the fissures in the sea ice by showing warmer areas of ice in a deeper blue and colder areas of sea ice in a brighter white. The sea ice extent is defined by a three-day moving average of the AMSR-E 12.5 km sea ice concentration, showing as ice all areas having a sea ice concentration greater than 15%. ||

Annual Sea Ice Cycle over Northern Canada
Read moreOver the course of a year, sea ice in northern Canada pulsates down into the Hudson Bay and retreats northward in the summer months. In the winter months where the sea ice extends down into the bay, polar bears wander onto the ice in search of food. As summer approaches and the sea ice melts, the bears wander back onto the mainland until the next winter. Data for this animation was gathered from the Aqua satellite's Advanced Microwave Scanning Radiometer for the Earth Observing System (AMSR-E). Aqua is a NASA satellite and the AMSR-E instrument onboard was provided by the Japan Aerospace Exploration Agency (JAXA).

2005 Sea Ice over the Arctic derived from AMSR-E
Read moreThis animation shows the Spring retreat and subsequent Autumn advance of sea ice over the Arctic from 1/1/2005 through 12/31/2005. The false color of the sea ice, derived from the AMSR-E 6.25 km brightness temperature, was designed to highlight the fissures in the sea ice. Moving 3-day minimum brightness temperatures provide a background for smooth ice movement over which the actual daily brightness temperatures were mapped for definition of the ice structures. The sea ice extent was defined by a 3-day moving average of the AMSR-E 12.5 km sea ice concentration, showing as ice all areas having a sea ice concentration greater than 15%. ||

Sea Ice Growth Slows In Arctic
Read moreArctic sea ice was at a record low wintertime maximum extent for the second straight year. || Every year, the cap of frozen seawater floating on top of the Arctic Ocean and its neighboring seas melts during the spring and summer and grows back in the fall and winter months, reaching its maximum yearly extent between February and April. On March 24, Arctic sea ice extent peaked at 5.607 million square miles, a new record low winter maximum extent in the satellite record that started in 1979. It is slightly smaller than the previous record low maximum extent of 5.612 million square miles that occurred last year. The new record low follows record high temperatures in December, January and February around the globe and in the Arctic. Scientists say as temperatures in the atmosphere and oceans continue to warm, we can expect to keep seeing smaller wintertime maximums in the future. Watch the video for a NASA visualization that shows the growth of Arctic sea ice from its 2015 summertime minimum extent to its 2016 winter maximum. ||

Sea Ice Maximum/Operation IceBridge Live Shots
Read moreB-roll and canned interviews will be added on Thursday, March 24 || Just three months into 2016 and already global temperatures – particularly in the Arctic – are far warmer than normal. Global temperatures for February were the warmest on record for that month.Nowhere is this warming trend felt more than in theArctic where the unusual wintertime warmth has contributed to record low wintertime sea ice extent. Arctic sea ice keeps the Polar Regions cold and helps regulate global temperatures. The shrinking of sea ice is a key indicator of our planet’s health.NASA is monitoring the health of the Arctic from space and the ground. In the coming days NASA will launch two missions – Operation Ice Bridge and OMG (Oceans Melting Greenland). These airborne and ground campaigns to the Arctic will take measurements of sea ice and glacier thickness.Join NASA scientists on Friday, March 25 from 6:00 a.m. – 11:30 a.m. EDT to see new images of this year’s sea ice extent; talk about how the Arctic faired this winter; and find out the latest on NASA missions to the Arctic set to launch in the coming days.Suggested Questions:1. What do the latest images show us about this year’s winter in the Arctic?2. What do the images tell us about the long-term trend?3. NASA is getting ready to send out teams of scientists to the Arctic in the comingdays. What will they be doing?4.

Arctic Daily Sea Ice Concentration from Arctic Minimum 2016 to Arctic Maximum 2017
Read moreThis movie begins at Arctic Minimum on September 10, 2016 and shows daily sea ice concentration until the Arctic maximum on March 7, 2017. The 2017 Arctic maximum was 14.42 million square kilometers (5.57 million square miles). The average maximum (1981-2010) is 15.64 million square kilometers. || This animation shows the seasonal change in the extent of the Arctic sea ice between the Arctic minimum, September 10, 2016, and Arctic maximum on March 7, 2017. Arctic sea ice appears to have reached a record low wintertime maximum extent, according to scientists at NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) in Boulder, Colo. This winter, a combination of warmer-than-average temperatures, winds unfavorable to ice expansion, and a series of storms halted sea ice growth in the Arctic. This year’s maximum extent, reached on March 7 at 5.57 million square miles (14.42 million square kilometers), is only about 40,000 square miles below the previous record low, which occurred in 2016, The images shown here portray the sea ice as it was observed by the AMSR2 instrument onboard the Japanese Shizuku satellite. The opacity of the sea ice is derived from the AMSR2 sea ice concentration. The blueish white color of the sea ice is derived from the AMSR2 89 GHz brightness temperature. The annual cycle starts with the minimum extent reached on August 31, 2016 and runs through the daily sea ice concentration until the maximum occurs on March 3, 2017. The Arctic’s sea ice maximum extent has dropped by an average of 2.8 percent per decade since 1979, the year satellites started measuring sea ice. The summertime minimum extent losses are nearly five times larger: 13.5 percent per decade. Besides shrinking in extent, the sea ice cap is also thinning and becoming more vulnerable to the action of ocean waters, winds and warmer temperatures. ||

Arctic Sea Ice Maximum - 2015
Read moreAn animation of the Arctic sea ice from October 1, 2014 to February 25, 2015 when the ice reached its maximum annual extent. The 2015 maximum is then compared to the average 1979-2014 maximum shown in yellow. A distance indicator shows the difference between the two in the Sea of Okhotsk north of Japan. || The maximum Arctic sea ice extent appears to have occurred on February 25, 2015, reaching an extent of 14.52 million square kilometers (5.61 million square miles). If the February 25 value holds, it would be one of the earliest maximums on record, 15 days earlier than normal, and the lowest extent in the satellite record starting in 1979. It is 129,500 square kilometers (50,000 square miles) below the previous lowest maximum recorded in 2011. Overall, there is a declining trend in the maximum extent of about 2.5 % 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 very little 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. ||

AMSR-E Arctic Sea Ice: September 2010 to March 2011
Read moreSea ice is frozen seawater floating on the surface of the ocean. Some sea ice is semi-permanent, persisting from year to year, and some is seasonal, melting and refreezing from season to season. The sea ice cover reaches its minimum extent at the end of each summer and the remaining ice is called the perennial ice cover.In this animation, the Arctic sea ice and seasonal land cover change progress through time, from the 2010 minimum which occurred on September 17 through March 16, 2011. Over the water, Arctic sea ice changes from day to day showing a running 3-day maximum 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 maximum of the AMSR-E 89 GHz brightness temperature. Over the terrain, monthly data from the seasonal Blue Marble Next Generation fades slowly from month to month. ||
