An animation of the annual Arctic sea ice minimum with a graph overlay showing the area of the minimum sea ice in millions of square kilometers.
This video is also available on our YouTube channel.
This visualization shows the expanse of the annual minimum Arctic sea ice for each year from 1979 through 2015 as derived from SSMI data. A semi-transparent graph overlay shows the area in million square kilometers for each year's minimum day. The date shown in the upper right corner indicates the current year being displayed.

Sea ice is frozen ocean water around the polar caps that, in the winter thickens and grows and in the summer thins and decreases. Arctic sea ice is important because it reflects sunlight and keeps the Arctic region cool. Over the past three decades, Arctic sea ice has dramatically declined; making what was once extraordinary low measurements the new normal. Join NASA scientists on Friday August 19th from 6:00 a.m. – 11:30 a.m. EDT to show your viewers new images from the Arctic, and talk about how the polar region is fairing this summer, and how long-term changes in this region could affect the way we live in the U.S. The Arctic is Earth’s air conditioner and it helps regulate global temperatures. But the region is warming twice as fast as elsewhere in the world, making the Arctic one of the most visible signs of a changing planet. NASA is keeping a close eye on changing conditions in the Arctic with its satellites, airborne and ground campaigns that are measuring the polar sea ice. Scientists are also monitoring the ice sheets that sit on land that are also melting at increasing rates. In 2018 NASA will launch the ICESat-2 satellite that will make some of the most advanced measurements of the polar regions ever. ** To book a window **Michelle Handleman/ michelle.z.handleman@nasa.gov / 301-286-0918 workHD Satellite Coordinates for AMC9-K17/Slot AB (18MHz): AMC-9 Ku-band Xp 17 Slot AB| 83.0 ° W Longitude | DL 12045.0 MHz | Horizontal Polarity | QPSK/DVB-S | FEC 3/4 | SR 13.235 Mbps | DR 18.2954 MHz | HD 720p | Format MPEG2 | Chroma Level 4:2:0 | Audio EmbeddedSuggested Questions:1.Globally it’s been the warmest year on record.

September 2007 Arctic Sea Ice vs 1979-2007 Average with Graph of 1979 to 2008 Ice Areas
Jan. 8, 2009, 7 p.m.
Read moreThe sea ice image with labels and the graph inset || Sea 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. The 2007 Arctic summer sea ice reached the lowest extent of perennial ice cover on record. The area of the perennial ice has been steadily decreasing since the satellite record began in 1979, at a rate of about 10% per decade. But the 2007 minimum, reached on September 14, is about 38% lower than the climatological average. Such a dramatic loss has implications for ecology, climate and industry.This image compares the difference between the perennial sea ice minimum area on September 14, 2007 and the 1979-2007 average minimum sea ice.

The sea ice cover reaches its minimum extent at the end of each summer and the remaining ice is called the perennial ice cover. The 2007 Arctic summer sea ice has reached the lowest extent of perennial ice cover on record - nearly 25% less than the previous low set in 2005. The area of the perennial ice has been steadily decreasing since the satellite record began in 1979, at a rate of about 10% per decade. But the 2007 minimum, reached on September 14, is far below the previous record made in 2005 and is about 38% lower than the climatological average. Such a dramatic loss has implications for ecology, climate and industry.This animation compares the difference between the perennial sea ice minimum extent on September 21, 2005 and September 14, 2007.

Every four years, the NCA is required to produce a report for Congress that integrates, evaluates, and interprets the findings of the USGCRP; analyzes the effects of global change on the natural environment, agriculture, energy production and use, land and water resources, transportation, human health and welfare, human social systems, and biological diversity; and analyzes current trends in global change, both human-induced and natural, and projects major trends for the subsequent 25 to 100 years. A draft of the Third National Climate Assessment report is available on the Federal Advisory Committee website. The final report is slated to be released in 2014. This scientific visualization of annual minimum sea ice area over the Arctic from 1979-2012 is one element of the NCA that highlights findings conveyed in the chapters of the draft Third NCA report. This record shows a persistent decline in the minimum extent of Arctic sea ice cover. The satellite observations are from passive microwave sensors and processed using the NASA Team algorithm developed by scientists at NASA Goddard Space Flight Center. The sensors that collected the data are the Scanning Multichannel Microwave Radiometer (SMMR) on the NASA Nimbus-7 satellite and a series of Special Sensor Microwave Imagers (SSM/I) and Special Sensor Microwave Imager and Sounders (SSMIS) on U.S. Department of Defense Meteorological Satellite Program (DMSP) satellites. The data from the different sensors are carefully assembled to assure consistency throughout the 34 year record.This visualization is similar to another developed by NASA, but is based on a slightly different algorithm to process the same sensor data. Both show similar downward trends in minimum sea ice area coverage over this time period. || Animated graph showing Annual Minimum Sea Ice Extent over the Arctic from 1979 to 2012.

Some sea ice is permanent, persisting from year to year, and some is seasonal, melting and refreezing from season to season. Because the extent of the sea ice is important both for the Arctic marine ecology and for the role it plays in the Earth s climate, understanding the variation of this extent during the year and from year-to-year is vital. Each year, the minimum sea ice extent in the northern hemisphere occurs at the end of summer, in September. By comparing the extent of the sea ice in September over many successive years, long term trends in the polar climate can be assessed.

Since 1999, this minimum has shown an ice extent that is consistently 10% to 15% smaller than the average extent over the past 20 years. || This element is the three-year moving average September mean sea ice concentration in the northern hemisphere from 1979-1981 through 2003-2005 without the date bar overlay. || This element contains the overlay date bar that indicates the range of years averaged to compute the September mean along with a month label in the upper left corner. || This animation dissolves between the 1979-1981 average September mean sea ice concentration and the 2003-2005 average September mean sea ice concentration. || This still image shows the September mean sea ice concentration computed from the years 2003 through 2005.

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.
