This Sea Ice Concentration image shows the extent of sea ice and snow melt in northern Alaska this spring. The region's unusual warmth this past winter reduced the annual Arctic sea ice maximum to its lowest level in the satellite record. In addition, snow at NOAA's Barrow Observatory (one of a network of observatories monitoring weather and climate in the Arctic) began melting on May 13, which is 10 days earlier than the previous record for Barrow set in 2002.
Established in 1973, the National Weather Service's Barrow, Alaska Observatory is located on the northern most point of the United States, about 8 km northeast of the village of Barrow, Alaska.
