Bar­ents­burg – 16th April, 2016

April is showing off with the best of clear, sta­ble, cold win­ter wea­ther. A trip to Bar­ents­burg often starts with a view over Lon­gye­ar­by­en. Dri­ving along the coast is a regu­lar part of fre­quent tou­rist tours to Bar­ents­burg, but you may not like the short, but steep ascents, espe­cial­ly when the sur­face is fro­zen over, if you are not used to dri­ving a snow mobi­le.

Who would have expec­ted to see a wal­rus on a win­ter trip to Bar­ents­burg? We also saw Rein­de­er and even White wha­les (Belugas), but too far away to take pho­tos.

Bar­ents­burg its­elf loo­ks part­ly like a big arc­tic ver­si­on of Lego­land after several years of refur­bish­ment. The choice of colours of some of the buil­dings might be a mat­ter of deba­te, but others are real­ly beau­ti­ful. Lenin is medi­ta­ting as always, the view direc­ted into the distance. Impos­si­ble to say what he would say about the colours.

Sur­ging gla­ciers in Spits­ber­gen

Several of Spitsbergen’s gla­ciers are on the move. A rather sud­den type of advan­ce cal­led gla­cial sur­ge is lin­ked to the inter­nal mecha­nics of ice move­ment. The­se gla­ciers are buil­ding up ice volu­me in the catch­ment area over deca­des to dischar­ge this wit­hin rela­tively short time (typi­cal­ly 1-2 years), some­thing that invol­ves rapid move­ment of up to an impres­si­ve 10 meters per day or even more. As a result, sur­ging gla­ciers are usual­ly stron­gly crev­as­sed.

This beha­viour has recent­ly been obser­ved at Penck­breen (Van Keu­len­fjord) and Aavaats­mark­breen. It is also cur­r­ent­ly known from other Sval­bard gla­ciers. Around 2014, the advan­ce of parts of the ice cap Aus­t­fon­na has attrac­ted atten­ti­on.

The sur­ge beha­viour is lin­ked to ice dyna­mics and not to a cli­ma­ti­cal­ly indu­ced posi­ti­ve mass balan­ce. Altog­e­ther, Spitsbergen’s gla­ciers are suf­fe­ring from a signi­fi­cant loss of ice volu­me, with a ten­den­cy to incre­a­sing speed of loss in recent years due to cli­ma­te chan­ge.
