Arnesenbreen, Svalbard Retreat, Separation and Surge

Arnesenbreen (A) and Bereznikovbreen (B) in 1990 and 2018 Landsat images.  Red arrow is 1990 terminus location, yellow arrow the 2018 terminus location and purple dots the transient snowline. Arnesenbreen and Bereznikovbreen are glaciers in Svalbard on the east coast of Spitsbergen that in 1990 had a joint calving front near Kapp Murchison. Blaszczyk et al’s (2009) analysis identified 163 Svalbard glaciers that are tidewater with the total length calving …

Has Fridtjovbreen, Svalbard Surged for the last time?

Fidtjovbreen, Svalbard comparison in 1998 and 2016 Landsat imagery.  Red arrow marks the 1998 terminus, yellow arrow the 2016 terminus and purple dots mark the snowline.  The Yellow numbers indicate area of separation between glaciers. Pink arrows indicate areas on the upper glacier where thinning is exposing more bedrock. F=Fridtjovbreen, S=Sagabreen, G=Gronfjordbreen Fridtjovbreen, Svalbard, is a tidewater-terminating glacier that started a 7-year surge advance during the 1990’s. This central Spitsbergen …

Strongbreen Retreat, Fjord Expansion, Svalbard

Strongbreen is a glacier in Svalbard on the southern part of Spitsbergen draining east into the Kvalvagen Fjord. Blaszczyk et al’s (2009) analysis identified 163 Svalbard glaciers that are tidewater with the total length calving ice−cliffs at 860 km for the 2001-2006 period. They observed that 14 glaciers had retreated from the ocean to the land over the last 30–40 year period. One glacier they observed having separated from neighboring …

Svitjodbreen Retreat, Northwest Svalbard

Svitjodbreen is a 10 km long tidewater outlet glacier in northwest Svalbard, Albert Land. The glacier drains north into Fugelfjorden, the highest elevation of the main glacier is 600 meters with a few neighboring peaks reaching 800 m, not very high. NW Svalbard is a region that has experienced extensive long term thinning from 1965 to 2007 (Nuth et al, 2010), with an average glacier wide thinning of 0.5 m/year …

Retreat of Nannbreen, Svalbard

Nannbreen is a 5 km long land terminating glacier in southwest Svalbard. The glacier is just north of Hornsund. During the course of the 20th century Nannbreen retreated from its Little Ice Age moraine complex forming a new proglacial lake. The glacier ends at an elevation of 150 meters descending from 600 meters, the snowline in several Landsat images from the last decade has been 400-450 meters. By 2000 (first …
