Arctic sea ice extent has been measured by satellites since the 1970s. For many people, September means the kids are back in school, football season is underway, and the end of summer has come. The 2019 wintertime extent reached on March 13 ties with 2007's as the 7th smallest. Arctic sea ice continues to dwindle as NASA says its volume dropped to the seventh-lowest extent on record this winter. Another month has passed and so here is the updated Arctic sea ice volume graph as calculated by the Pan-Arctic Ice Ocean Modeling and Assimilation System (PIOMAS) at the Polar Science Center: As you can see, 2019 has moved into second place on the PIOMAS volume graph. On September 17, the area covered by. This was 479,000 square miles below the 1981 to 2010 long-term average extent and 89,000 square miles below the previous. - Extent gain 122k, 96k above average (last 10 years) for the day, the 4th day of very high gains. 60 million square miles (4. But is this a major climate event. Researchers are still waiting for Arctic sea ice to bottom out this year. Analysis of satellite data by NSIDC and NASA showed that the extent of ice cover this year effectively tied 2007 and 2016 as the second lowest in the satellite record, which dates back to late 1978. Russia’s national ice hockey team has been defeated by the Czech team 0:3 in third match of the 2019 Karjala Cup, the first stage of the Euro Hockey Tour. "Arctic sea ice has thinned, concurrent with a transition to younger ice. 15 million square kilometers) , this year's summertime extent is effectively tied for the second in the satellite record, according to NASA and the National Snow and Ice Data Center. Sea ice cover typically reaches its maximum amount in March, then reaches its minimum in September. Arctic sea ice likely reached its 2019 minimum extent of 1. Arctic researchers will lock this ship in ice for a year to study the changing polar region. Area = sum of area elements weighted with concentration in this element. This is all just a predictable result of the evils of Man Made Climate Catastrophe. The lowest-ever recorded Arctic sea ice area and volume occurred in September 2012. A new 800-year reconstruction of Western Arctic Ocean sea ice variability (Porter et al. with the Antarctic continent geography, is a dominant driver of sea ice variability in the Pacific sector of the Antarctic (Raphael et al. 15 million square kilometers), this year's summertime extent is effectively tied for the second in the satellite record, according to NASA and the National Snow and Ice Data Center. For many people, September means the kids are back in school, football season is underway, and the end of summer has come. (2007, 2012 & 2016 highlighted). 2019 is shown in blue and 2012 in dotted green. 2019 is shown in blue, 2018 in green, 2017 in orange, 2016 in brown, 2015 in purple, and 2012 in dotted brown. The 'normal' or average limit of sea ice (orange line) is defined as 15% sea ice cover, according to the average of satellite observations 1981-2010 (both years inclusive). Analysis of satellite data by NSIDC and NASA showed that the extent of ice cover this year effectively tied 2007 and 2016 as the second lowest in the satellite record, which dates back to late 1978. 1: Can fluctuations in Arctic sea ice cover influence our weather? November 1 In the News, November 2, 2019 Carmen Giménez Smith to give reading. A year of nonstop Arctic heat. For the August report, the pan-Arctic median value for the September 2019 sea-ice extent is 4. The big picture is clear: After an Arctic summer with well above-average temperatures, warmer seas, and a historic July heat wave, sea ice has vanished in Alaskan waters. English: Plot of monthly mean values of the area of the arctic sea ice, based on data of NSIDC. About Arctic Sea Ice Extent Sea ice extent is estimated using daily satellite images to calculate the total ocean area that has an ice concentration of 15% or more. Back to E&E News index page. The median extent is based on the period 1981-2010. The below graph shows the big picture: arctic sea ice extent has declined (in fits and starts) since the satellite record began in 1979. Arctic sea ice extent for November 2016 was 9. National Snow and Ice Data Center (NSIDC) recorded an Arctic sea ice extent of 7. This was the seventh lowest in the satellite record, with below. 15 million square kilometers) on 18 September, tied for second lowest summertime extent in the satellite record, according to data provided by NASA and the National Snow and Ice Data Center.
