Multi decadal glacier area fluctuations in Pan-Arctic

S. H. Mernild and J. K. Malmros

Abstract. The shrinking of land-terminating glaciers and ice caps (GIC) has been documented in high-latitude regions, even though repeat observations upon which to base such studies have been limited in space. Here, we present a new record of satellite-derived area changes for 321 land-terminating GIC throughout Pan-Arctic and for the W. Canada and W. US, with focus on the period from mid-1980s to late-2000s/2011 (the last ca. 25 yr). The mean shrinking rate was −0.06±0.01 km2 yr−1 during a period with climate warming. Most of the observed GIC shrank in area, more so than previously believed: while only 8% advanced. The analysis indicates that the observed GIC have lost an arithmetic average of one-fifth of their area since the mid-1980s (equal to a shrinking rate of ca. −1% yr−1), with the highest rate of loss of −40±4% (−1.7 % yr−1) in Alaska, and the lowest rate of loss of −12±3% (−0.5 % yr−1) in Arctic Russia.
