Twenty-one years of mass balance observations along the K-transect, West Greenland

Abstract

A 21-yr record is presented of surface mass balance measurements along the Ktransect. The series covers the period 1990–2011. Data are available at 8 sites along a transect over an altitude range of 390–1850m at approximately 67 N in West Greenland. The surface mass balance gradient is on average 3.8×10−3 mw.e.m−1 5 , and the mean equilibrium line altitude is 1553ma.s.l. Only the lower 3 sites within 10 km of the margin experience a significant increasing trend in the ablation over the entire period. Data are available at: http://doi.pangaea.de/10.1594/PANGAEA.779181.
