What is Up in Disko-Uummannaq Bay Greenland January 9-16, 2016

@TenneyNaumer contacted Alun Hubbard, Jason Box and I with an astute observation last evening. “But what I am getting at is that in general the temperature anomalies over the region of Jakobshavn have been high in the last few days, and I spotted weird temperatures off the coast via Climate Reanalyzer (which is seriously low resolution).  I just checked with the manati satellite (also seriously low resolution), and it seems …

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 …

Greenland Fjord Going Ice Free

Google Earth image from 2010 of Alangordlia Fjord At the AGU 2015 meeting a clear change from 15 years ago is the interdisciplinary nature of most research featured in most sessions.  In the glacier sessions there is physical oceanography, biology, climatology etc.to add in.  I will examine a SW Greenland Fjord, Alangordlia to illustrate this.  In 1987 Landsat image there are four glaciers reaching tidewater in the fjord and two …

Russell Glacier, Greenland Rapid Snowline Rise K-Transect 2015

Landsat Image based Watson River discharge sequence June 14-July 8, 2015 It was 30 years ago I first participated in Greenland Ice Sheet research, there was not much of it at the time.  However, there was the recognition of the importance for sea level rise with global warming, and this was driving an increase in research at that time. The level of research has increased exponentially in the last decade. One …

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 …

Upernavik Glacier Retreat, NW Greenland

Box and Decker (2011) focused on the changes in the terminus of 39 Greenland Outlet glaciers from 2000-2010. Of these 35 had experienced net loss with the collective loss of 1593 km2 over the last decade. (Box and Decker, 2011). The retreat has occurred irrespective of the different characteristics of various glaciers (Bailey and Pelto, SkS) One of the glaciers in this group is Upernavik Glacier on the NW Greenland …
