This web page presents first, preliminary results and images of work carried out as part of a project supported by NSF's Russian-American Initiative on Shelf-Land Environments in the Arctic (RAISE). For further details feel free to contact the PIs associated with this project.

We are also collaborating with colleagues from German Research Institutes who have been involved in joint research in the Laptev Sea for the past several years (System Laptev Sea Program and Transdrift expeditions).

Financial support through NSF Grant OPP-9876843 is gratefully acknowledged. Analysis of Radarsat SAR data was made possible through a NASA ADRO grant. Graduate and exchange students Karoline Frey, Uli Blahak, Markus Hasel and Andreas Schmidt were involved to various degrees in this research and we thank them for their help.
