Winter sea ice on the Arctic Ocean covered the second smallest area on record this year, part of a thaw that is opening the region to shipping and oil exploration and may be disrupting weather far to the south, scientists said on Friday.
The extent of floating ice likely reached an annual maximum of 14.5 million square kilometers (5.6 million square miles) on March 17, fractionally bigger than a record set in 2017, the U.S. National Snow and Ice Data Center (NSIDC) said.

  Arctic sea ice appears to have reached its annual maximum extent on March 17. This is the second lowest Arctic maximum in the 39-year satellite record. The four lowest maximum extents in the satellite record have all occurred in the past four years. NSIDC will post a detailed analysis of the 2017 to 2018 winter sea ice conditions in our regular monthly post in early April.
  Overview of conditions
  On March 17, 2018, Arctic sea ice likely reached its maximum extent for the year, at 14.48 million square kilometers (5.59 million square miles), the second lowest in the 39-year satellite record, falling just behind 2017. This year’s maximum extent is 1.16 million square kilometers (448,000 square miles) below the 1981 to 2010 average maximum of 15.64 million square kilometers (6.04 million square miles).
  The four lowest seasonal maxima have all occurred during the last four years. The 2018 maximum is 60,000 square kilometers (23,200 square miles) above the record low maximum that occurred on March 7, 2017; 40,000 square kilometers (15,400 square miles) below the 2015 and 2016 maxima (now tied for third lowest); and is 190,000 square kilometers (73,400 square miles) below the 2011 maximum, which is now fourth lowest.
  In March 2017, we reported a new record maximum being set, with 2016 sliding to the second lowest, and 2015 the third lowest. In November 2017, we updated our calculation of the monthly average sea ice extent in the NSIDC Sea Ice Index, resulting in 2016 tying with 2015.
  The date of the maximum this year, March 17, was five days later than normal compared to the 1981 to 2010 median date of March 12.

Low ice, low snow, both poles | Arctic Sea Ice News and Analysis
▻http://nsidc.org/arcticseaicenews/2016/06/low-ice-low-snow-both-poles
Daily Arctic sea ice extents for May 2016 tracked two to four weeks ahead of levels seen in 2012, which had the lowest September extent in the satellite record. Current sea ice extent numbers are tentative due to the preliminary nature of the DMSP F-18 satellite data, but are supported by other data sources. An unusually early retreat of sea ice in the Beaufort Sea and pulses of warm air entering the Arctic from eastern Siberia and northernmost Europe are in part driving below-average ice conditions. Snow cover in the Northern Hemisphere was the lowest in fifty years for April and the fourth lowest for May. Antarctic sea ice extent grew slowly during the austral autumn and was below average for most of May.

NunatsiaqOnline 2015-09-09: NEWS: Arctic sea ice nearing annual minimum extent: data centre

If you live near Baffin Bay or Hudson Bay, you might have trouble accepting the forecasts showing that this year’s minimum sea ice extent, which typically occurs in mid to late September, is likely to come in as the third or fourth lowest in the satellite record.
But that’s the latest from the Colorado-based National Snow and Ice Data Center, which issued its latest news last week, based on recent satellite images.

Scientists link frozen spring to dramatic Arctic sea ice loss | Environment | guardian.co.uk
▻http://www.guardian.co.uk/environment/2013/mar/25/frozen-spring-arctic-sea-ice-loss
Climate scientists have linked the massive snowstorms and bitter spring weather now being experienced across Britain and large parts of Europe and North America to the dramatic loss of Arctic sea ice.
Both the extent and the volume of the sea ice that forms and melts each year in the Arctic Ocean fell to an historic low last autumn, and satellite records published on Monday by the National Snow and Ice Data Centre (NSIDC) in Boulder, Colorado, show the ice extent is close to the minimum recorded for this time of year.
