Flatisen Glacier, Norway Retreats from Lake & Separates
Flatisen Glacier in Landsat images from 1990 and 2018. The glacier terminates in the proglacial lake in 1990 at the red arrow and in 2018 at the yellow arrow no longer terminating in the lake. The pink arrows indicate three connections of the ice cap to the terminus tongue in 1990, with two lost by 2018. Flatisen is the primary outlet glacier on the southern side of the second largest …

Harbardsbreen, Norway Margin Retreat and Separation
Harbardsbreen (H) the 13th largest ice cap in Norway in 1988 and 2014 Landsat images. Red arrows indicate the main terminus on the east side that has separated since 1988. Point 1 is the sole nunatak in 1988 now there are more. The Pink arrow is the location of the narrowing connection with the northern section of the icecap. The east side of the ice cap feeds the hydropower system …

Engabreen Glacier, Norway Retreat
Engabreen is an outlet glacier of the Svartisen ice cap in northern Norway. It has an area of 40 km2. Most of the area lies between 1200 and 1450 m the high plateau of the ice cap. This glacier has been the focus of attention from the Norwegian Water Resources and Energy Directorate (NVE) for over 50 years. Google Earth image of Engabreen Glacier, 2014. NVE maintains the most extensive …

Langfjordjokulen, Norway Retreat-Thinning
Langfjordjokulen is in the Finnmark region of northern Norway. This is a plateau glacier with a valley glacier extending east toward Langfjordhamm. The Norwegian Water Resources and Energy Directorate has monitored the length change and mass balance of this glacier from 1989-2014. The mean mass balance has been significantly negative averaging -0.7 m/year, with every year being a net loss since 1997. This is no way to sustain a glacier …

Spørteggbreen Separation and Retreat, Norway
Spørteggbreen is a small ice cap just east of Jostdalsbreen, Norway’s largest ice cap. The Norway Glacier atlas chronicles the area of the 10 glaciers that comprise the ice cap at 23.8 square kilometers in 2006 (Andreassen and Winsvold, 2012). The Norwegian Water Resources and Energy Directorate (NVE) has an excellent glacier monitoring program that monitors 10 glaciers that drain Jostedalsbreen from 2008-2013 the net change was retreat on all 10. This is …

Vestisen Glacier Retreat, Norway
Vestisen Glacier is the second largest glacier of the Oksindan Icecap flows west. The glacier drains west into the Rossaga River, which has a Statkraft Hydropower plant, though upstream of the glacier inflow. Here we examine Landsat imagery from 1992-2014 to observe recent changes. Vestisen Mapcarta view In 1994 the glacier terminus is at the red arrow. The areal extent of snowcover is more than 50% of the glacier area, …

Austre Okstindbreen Retreat, Norway
Austre Okstindbreen is the largest glacier of the Okstindan Icecap. It flows north from the 1700 m to a terminus in a proglacial lake at 900 m. The lake drains into Grasvatnet. The glacier had a sustained retreat of 2 km from 1908-1980, emplacing annual moraine ridges during the 1950-1968 period (Worsley and Ward, 1974). The other main glacier of the Oksindan Icecap is Vestisen. Knudsen and Theakstone (1988) identified …

Lodalsbreen Retreat, Norway
Lodalsbreen is an outlet glacier from the northeast region of the Jostedalsbreen Icecap of Norway. This particular outlet is difficult to reach and not often investigated, for this icecap in general all 10 glaciers observed from 2000-2010 have retreated (Norwegian Water Resources, 2010). Recent work by Nussbaumer et al (2011) and Imhof et al (2011) have focussed on the changes in terminus postion of Jostedalsbreen glaciers since the Little Ice …

Tunsbergdalsbreen Glacier Retreat, Norway
The Norwegian Water Resources and Energy Directorate (NVE) has an excellent glacier monitoring program. Of these ten drain the largest ice cap in Norway the Jostedalsbreen, from 2008-2013 the net change was retreat on all 11. The largest outlet glacier Tunsbergdalsbreen is not one of the closely monitored glaciers. This glacier flows southeast from the icecap, is 18 km long and terminates at 670 meters in a new proglacial lake. …

Midtdalsbreen Glacier, Norway retreat Continues in 2010
The Norwegian Water Resources and Energy Directorate is the most extensive national glacier monitoring program in the world. They noted in 2010 that 27 of 31 glaciers monitored retreated. Midtdalsbreen near Finse drains the eastern portion of the Hardangerjøkulen (Hardanger ice Cap). This glacier retreated 34 meters from 2009 to 2010 and has retreated 143 meters in the last 10 years. This retreat is less than the retreat of Rembesdalsskaka …
