Storbreen, Svalbard Major Retreat Opens New Fjord
Storbreen, Svalbard in 1990 and 2017 Landsat images. The red arrows indicate 1990 terminus , yellow arrow the 2017 terminus and purple dots the snowline in 1990. A recent snow storm has obscured the actual snowline in Aug 2017. Storbreen Glacier (ST) terminates on the north side of Hornsund in southern Svalbard. From 1990 to 2017 Storbreen has experienced a substantial retreat opening a new fjord and separating from Hornbreen …

1990 and 2014 Landsat images indicating Paierbreen (P), Muhlbacherbreen (MU) and Hansbreen (H). The red arrow and red dots indicate the 1990 terminus location and yellow arrows and yellow dots the 2014 terminus location. The purple arrow indicates the location of a supraglacial lake that was persistent in the 1990’s but is no longer evident in 2013, 2014 and 2015. From 1990 to 2014 all four of the glaciers terminating …

Samarinbreen, Svalbard Rapid Retreat 1990-2014
Samarinbreen (SA) 1990 left, and 2014 right, Landsat image comparison. KO=Korberbreen, CH=Chomjakovbreen, ME=Mendeleevbreen Red arrows indicate 1990 terminus position, yellow arrows 2014 terminus. and purple dots the snowline. Samarinbreen terminated in a calving front in Samarinvagan, a bay on the southern side of Hornsund Fjord. Hornsund is a fjord that in 2015 almost cuts through the southern Island of Svalbard, due to the retreat of Hamberbergbreen and Hornbreen. The Institute of …

Vasilievbreen Glacier Retreat, Svalbard
Vasilievbreen is a glacier that terminates on the east coast of the southern island of Svalbard a short distance southeast of Hornsund. In 1990 this glacier had a single continuous terminus margin along the coast. The glacier retreated 50 m/year from 1936 to 1990, as the embayment of Isbukta expanded. The glacier has since separated into distinct termini, on each image colored arrows indicate the same specific location, red arrow …

Retreat of Hansbreen, Svalbard
Hansbreen is tidewater glacier flowing into Hornsund in sw Svalbard. The glacier has been examined in detail over the last twenty years from the Polish Research Station. The glacier has retreated 2.7 kilometers from 1900 to 2008. The chart below from Oerlemans, Jania and Kolandara (2011) illustrates this retreat as does the comparative images from the Polish Research Station. The glacier mass balance has been measured since 1989 and is …
