New Research Paper With Members of the Permafrost Lab

Expert assessment of vulnerability of permafrost carbon to climate change, E.A.G. Schuur and 42 co-authors (July 2013) is online at Climate Change.
Approximately 1700 Pg of soil carbon (C) are stored in the northern circumpolar permafrost zone, more than twice as much C than in the atmosphere. ...

First issue of "Changing Ice" published: A newsletter of Cryosphere Research in Alaska

The first newsletter "Changing Ice" targeting Cryosphere research in Alaska has been published and features several research examples from the GI Permafrost Lab. With this newsletter projects and discoveries led by Alaskan Cryosphere scientists are highlighted with the hope to create a tool that allows efficient communication between scientists and stakeholders.

Leaking lakes featured in NASA Publication: Sensing our Planet

Work on thermokarst lakes by Guido Grosse and colleagues Katey Walter Anthony and Melanie Engram is being featured in NASA's annual outreach publication "Sensing our Planet", which highlights current NASA Earth Science Research. The article "Leaking Lakes" was published in November 2012 and can be found here.

New Report on Thawing Permafrost Released by UNEP

A new report on thawing permafrost "Policy Implications of Warming Permafrost" was just released with Vladimir Romanovsky as one of the contributing authors. Read the summary here or download the full report from the link below.

Permafrost thaw and receding glaciers enhance geologic methane seepage

A new article published in Nature Geoscience led by Dr. Katey Walter Anthony and co-authored by Dr. Guido Grosse from the GI Permafrost Lab highlights findings of geologic methane seepage in zones of Arctic permafrost thaw and receding glaciers. Results indicate that in a warmer future climate, deep geologic methane sources currently trapped under a Cryosphere cap may increasingly contribute to the greenhouse gas budget of the Earth's atmosphere as this cap is degrading.

Recent Paper on Sea-bed Permafrost North of Barrow, Alaska (Beaufort Sea) and Degradation

A recent paper, Dr. Vladimir Romanovsky is co-author, details seabed geoelectric field observations of ice-rich sea-bed permafrost and estimate of the degradation rate. Sea-bed permafrost like permafrost on land can hold substantial amounts of methane, a very potent greenhouse gas. Degradation of sea-bed permafrost on the shallow continental shelves of the coastal seas of the Arctic Ocean could 'ignite' a substantially positive feedback loop with the atmosphere-land-ocean systems in the Arctic with global impact. The paper is published in JGR - Earth Surface, v.

All good things come in threes: Third paper on permafrost and thermokarst dynamics highlighted by JGR Biogeosciences

A third paper resulting from our group's work on permafrost and thermokarst dynamics, funded by NASA Carbon Cycle Sciences and the NSF Arctic Program, was now selected as Editors' Highlight in Journal of Geophysical Research - Biogeosciences and as Research Spotlight in EOS.
