Field sites and observatories
At the moment our group is working at test sites close to Ny Alesund, Svalbard (Norway), at Samoylov Island (Siberia) and at Trail Valley Creek (Mackenzie Delta, Canada).
In the past we were also working at Polar Bear Pass in Alaska.
Samoylov, Lena Delta, Sibiria
On Samoylov Island , located in noth-west Siberia, we operate three automatic stations (Samoylov soil and climate station, Polygon Lake station, open-path Eddy Covariance). Addionally,an closed-path Eddy Covariance System is operated during the summer month.
Bayelva, Svalbard, Norway
Trail Valley Creek, Mackenzie Delta, Canada
Trail Valley Creek is located around 50 km North of Inuvik in the North-Western Territories in Canada.
It is the testsite for the research project PermaSAR and the main focus is on landsurface subsidence or heave caused by permafrost processes such as thawing and freezing.
Polar Bear Pass, Alaska
The Polar Bear Pass wetland area on Bathurst Island (75°40'N, 98°30'W) is the second largest wetland in the Canadian High Arctic with an area of 20 x 5 km². The wetland is a mosaic of land types comprising ponds, lakes and zones of dry ground that alternate with wet areas in a range of only a few meters.
Our research at Polar Bear Pass aims to identify key surface paramaters for the quantification of energy and water fluxes at the regional scale via aerial pictures and satellite data. Methods include the operation of two automatic soil stations, high-resolution aerial photography with a kite, spectrometry and ground-penetrating radar.
