Transporting Ice From Greenland’s Deep Interior

The North East Ice Stream is a fast-flowing glacier transporting ice from deep in the interior of the Greenland Ice Sheet out to the coast (see image showing a deep penetration into central Greenland). When it reaches the coastline it feeds 79 N Glacier. This area is heavily crevassed, evidence of the rapid ice flow. The cold blue ice and bare earth of 79 N seems particularly forbidding – even snow won’t settle here.

It is a two hour transit from Thule, in the north west corner of Greenland, to the survey area. The area is flat, white and empty. The only excitement is when we pass over the likely site of the old “Camp Century,” now buried under the ice, and moving with its flow. I note a “likely” site because the coordinates we have for it are old, and it will have moved. It is possible that one of the radar systems will be able to see where it sits now under the snow.

Located about 800 miles from the North Pole, Camp Century was a nuclear powered research facility built under the ice ~ 50 years ago by the US Army Corps of Engineers. For several years the camp operated as a mini city beneath the ice ignoring the forbidding environment, sub zero temperatures, winds that exceeded 125 mph, and an annual snowfall of almost 4 feet a year. However, the constant movement of the glacier forced the inhabitants to complete regular and extensive maintenance, which closed the camp after only 7 years.

Recent record-breaking heat waves have affected communities across the world. The Extreme Heat Workshop will bring together researchers and practitioners to advance the state of knowledge, identify community needs, and develop a framework for evaluating risks with a focus on climate justice.
