6th Symposium on the Impacts of an Ice-Diminishing Arctic on Naval and Maritime Operations 14-16 July 2015


Each topic linked below include images and animations that illustrate the current state of Arctic ice.

2015 Arctic Sea Ice Maximum Annual Extent Is Lowest On Record - March 2015

NASA - 2015 Arctic Sea Ice Maximum Annual Extent Is Lowest On RecordThe sea ice cap of the Arctic appeared to reach its annual maximum winter extent on Feb. 25, according to data from the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado, Boulder. At 5.61 million square miles (14.54 million square kilometers), this year's maximum extent was the smallest on the satellite record and also one of the earliest.

NASA Study Shows Global Sea Ice Diminishing, Despite Antarctic Gains - February 2015

Global Sea Ice Diminishing, Despite Antarctic GainsSea ice increases in Antarctica do not make up for the accelerated Arctic sea ice loss of the last decades, a new NASA study finds. As a whole, the planet has been shedding sea ice at an average annual rate of 13,500 square miles (35,000 square kilometers) since 1979, the equivalent of losing an area of sea ice larger than the state of Maryland every year.

Old ice in Arctic vanishingly rare - January 2015

Arctic Sea Ice  Old ice in Arctic vanishingly rareSince the 1980s, the amount of perennial ice in the Arctic has declined. This animation tracks the relative amount of ice of different ages from 1987 through early November 2014. The oldest ice is white; the youngest (seasonal) ice is dark blue. Key patterns are the export of ice from the Arctic through Fram Strait and the melting of old ice as it passes through the warm waters of the Beaufort Sea.

Arctic Sea Ice - On the Decline - December 2014

Arctic Sea Ice - On the DeclineThis video from NOAA's Ocean Today site discusses how arctic sea ice reached its maximum extent for the year on March 21 at 14.8 million square kilometers (5.70 million square miles), making it the fifth lowest maximum in the satellite record.

2014 Arctic Report Card: Visual Highlights - December 2014

Visual Highlights of the 2014 Arctic Report CardThe latest installment of NOAA's Arctic Report Card confirms that Arctic air temperatures are rising at more than twice the rate of the planet as a whole. The amount of ice that survives the summer melt season is shrinking, and water temperatures are rising. Some polar bear populations are declining. The number of snow days is falling. The Greenland Ice Sheet is becoming less able to reflect incoming sunlight.

Arctic Sea Ice Minimum for 2014 - September 2014

NOAA VisLab - Arctic Sea Ice Reaches Minimum Extent for 2014According to analysis by the National Snow and Ice Data Center, sea ice in the Arctic reached its annual minimum on September 17, 2014. At 5.02 million square kilometers or 1.94 million square miles, this was the sixth lowest amount of ice on record since satellite observations began in 1979. This image, using microwave data from the SSMIS sensor on the DMSP satellites, shows the sea ice concentration on September 17, 2014, along with a yellow line indicating the median sea ice extent for 1981-2010.

Glacial Runoff Plume in the Gulf of Alaska - August 2013

NASA Earth Observatory - Copper River DeltaNamed for the ore deposits found upstream, the Copper River drains an area of more than 24,000 square miles and flows into the Gulf of Alaska. By volume of discharge, it is the tenth largest river in the United States. Its delta forms one of the largest and most productive wetlands on the Pacific Coast of North America. "The glaciers in this area are receding at some of the fastest rates in the world, which can have all kinds of impacts on the local ecosystems," said Robert Campbell, research oceanographer at the Prince William Sound Science Center. Scientists are trying to figure out what exactly these impacts will be in the Copper River watershed.
