Supercomputer Essential for Permafrost Modeling

Geophysical Institute Quarterly, volume 22, number 4, 2010. Dr. Sergei Marchenko of the GI Permafrost Lab was featured. From the article, "Geophysical Institute permafrost researchers rely on the Arctic Region Supercomputing Center to help create simulations predicting the future of permafrost in both Alaska and Siberia. 'We can expect degradation of the current permafrost'," said Dr. Marchenko.

ARCUS Witness the Arctic reports on Permafrost Lab project

In its most recent issue (2010, vol. 13, iss. 4), the ARCUS online publication Witness the Arctic features a project collaboration between UAF climate modelers and GIPL: Project Integrates Permafrost Science and Climate Change Modeling

Why permafrost is thawing, not melting

This week the AGU journal EOS published a FORUM article discussing the wording that is used when permafrost warms above 0 degree Celsius. Currently both 'permafrost melting' and 'permafrost thawing' are widely used. In this article we describe the implications that either term has for understanding permafrost and permafrost degradation processes. Our conclusion is supporting that of earlier permafrost researchers: permafrost thaws, ice melts. A considerable portion of permafrost contains no ground ice, and therefore can hardly melt.

Reginald Muskett Attends GOSAT Principal Investigator Meeting in Kyoto, Japan

On January 26 through 29, Reginald Muskett, Postdoctoral Fellow of the Geophysical Institute and Permafrost Laboratory attended the International Workshop for Greenhouse Gas Measurements from Space -6 and the Greenhouse Gases Observing Satellite (GOSAT) Principal Investigator Meeting in Kyoto, Japan. The workshop and meeting were held consecutively in the International Conference Center, site of the 1997 UN Kyoto Protocol meetings. Dr.

Methane from Thawing Permafrost - Scientific American

An article on methane from thawing Permafrost was recently (December 2009) published in the Scientific American by our colleague Dr. K. Walter Anthony. It features fieldwork on thermokarst lakes in the Arctic and several projects in which GI Permafrost Lab members are involved.
