Arctic Sea Ice Volume Anomaly

Sea Ice Volume is calculated using the Pan-Arctic Ice Ocean Modeling and Assimilation System (PIOMAS) developed at APL/PSC by Dr. J. Zhang and collaborators. Anomalies for each day are calculated relative to the average over the 1979 -2009 period for that day to remove the annual cycle. The model mean seasonal cycle of sea ice volume ranges from 28,600 km^3 in April to 14,400 km^3 in September. The blue line represents the trend calculated from January 1 1979 to the most recent date indicated on the figure. Total Arctic Ice Volume for March 2010 is 20,300 km^3, the lowest over the 1979-2009 period and 38% below the 1979 maximum. September Ice Volume was lowest in 2009 at 5,800 km^3 or 67% below its 1979 maximum. Shaded areas represent one and two standard deviations of the anomaly from the trend. Updates will be generated at 3-5 day intervals.(more)
