Tibet Plateau 2014

Dr. Sergey Marchenko of the GI Permafrost Lab field research visit to the Tibet Plateau, and Lanzhou city, Gansu Province, China. Working for ten days at of 4,500-4,800 m asl was a challenging experience.

Canadian Arctic 2010

On this trip we drove from Fairbanks to Dawson City. Then we caught a charter flight on a Twin Otter to Inuvik, NWT Canada. Then on to Mould Bay on Prince Patrick Island and a couple of attempts at getting into Isachsen on Ellef Ringnes Island. We never made it into Isachsen because of the fog. Then on to Green Cabin on Banks Island.

Seward Peninsula June 2008

This album contains images from Guido's expedition to the Seward Peninsula, Alaska, in June 2008. We worked in the Cape Espenberg lowland around the Kitluk river mouth, based out of a nice little camp. Together with four colleagues from the Alfred Wegener Institute for Polar and Marine Research Potsdam, Germany, and one from the Senckenberg Institute Weimar we sampled permafrost sediments and ground ice in coastal exposures, surveyed recent plant communities and ostracod fauna, and did geophysical surveys of permafrost sediments. The fieldwork was funded by NSF, NASA and the Alfred Wegener Institute.

Kolyma August 2009

This album contains images from Guido's expedition to the Kolyma region, Northeast Siberia, in August 2009. Our small group from UAF and Russian partners from Moscow State University and the North East Science Station worked around Cherskii and by boat and all-terrain vehicle around Cape Maly Chukochy, about 70 km northwest of the Kolyma river mouth. We collected sediment samples from permafrost exposures on bluffs along rivers, lake shores and coasts to study how old thermokarst lakes are in the region, how they form, and what their sedimentologicla and biogeochemical (i.e. carbon) dynamics are. By thawing permafrost and providing anaerobic environments for decomposition of organic material in the thaw bulbs and lake sediments, thermokarst lakes emit large amounts of methane, an important greenhouse gas.
