Orpissuup Tasia Glacier slowdown, SW Greenland
Tedstone et al (2015) Figure 3 illustrates the widespread velocity decline along three transects. Pelto et al (1989) after a field campaign we mounted in 1985 and 1986 on Jakobshavns Glacier noted that the velocity was essentially the same in the summer of 1964, 1976, 1978, 1985 and 1986. Further we observed that the agreement between surface mass-balance and volume-flux calculations, suggested that “Jakobshavns Isbrae: is almost in a state of equilibrium”. The point …

Island Separates from Greenland Ice Sheet in 2014, Steenstrup Glacier
The retreat of outlet glaciers along the Greenland coast continues to change the maps of the region, Steenstrup Glacier located at 75.2 N in Northwest Greenland is an example of this. The glacier terminates on a series of headlands and islands, the glacier immediately to the south is Kjer Glacier. The boundary between Steenstrup Glacier and Kjer Glacier is Red Head, Steenstrup Glacier’s northern margin is near Cape Seddon. Here …

Greenland Glacier Change Index
This is an index of posts on the response of specific Greenland glaciers to climate change. In the 1980’s when I first worked on Jakobshavn Isbrae, Greenland there was not much research occurring on the glaciers. Today in response to the dynamic changes discussed below and glacier by glacier in the index links, Greenland is the focus of numerous extensive, ongoing and important research projects. In 2015 scientists are gearing …

Bussemand Gletscher Retreat East Greenland
Bussemand Gletscher in East Greenland has a mixed tidewater and land based terminus. This glacier is 50 km west of Tasiilaq and just west of Nattivit Kangertivat Fjord. In this post we compare Landsat imagery from 2000 and 2012 to determine the response of this glacier to recent climate change. Espen Olsen provided the base map below and noted that Bussemand translates to bogey man.. The first two images below …
