CASE – Circum-Arctic Structural Events - is a project run by the German Federal Institute for Geoscience and Natural Resources (BGR). Since 1992, some 20 CASE-expeditions were carried out to Svalbard, Greenland, Siberia, Yukon North Slope and the Canadian Arctic to do geological and geophysical terrestrial research and to study the geological development of the Arctic. With those expeditions, BGR is giving scientists involved in the CASE-program a significant and unique opportunity to study and compare the rocks, the evolution of sedimentary basins and the plate tectonic history of circum-Arctic areas.
In March, more than 70 geologists and geophysicists from Denmark, France, UK, Canada, Netherlands, Norway, Poland, Russia, Sweden, the US and Germany met in Hannover to discuss the newest development in circum-Arctic research. ARCEx-members Jan Inge Faleide, Snorre Olaussen and Malte Jochmann joined the international CASE-workshop to present their research results from Svalbard and the Barents Sea. Malte Jochmann has earlier been member of the Spitsbergen-expeditions CASE 10 and 17 which were carried out in 2007 and 2015, respectively.
During the meeting, Malte presented new findings: Paleocene tectonic movement unveiled by the sedimentary record on Svalbard, while Snorre presented an overview of the upper Mesozoic in north: Review of the Middle Jurassic to Lower Cretaceous clastic wedge in Svalbard and the Barents Sea. Jan Inge presented two talks: (1) Late Paleozoic- Mesozoic basin evolution in the SW Barents Sea –North Atlantic – Arctic links and (2) Cenozoic evolution of the western Barents Sea – Svalbard margin.
With the CASE-expeditions, the BGR has managed to perform land geology in remote and difficult accessible areas, such as the New Siberian Islands, Severnaya Zemlya, Ellesmere or Banks Island. More expeditions are planned, like North East Greenland to study the Wandel Sea Basin in 2018. ARCEx-member Malte Jochmann has gotten an invitation to join and we hope that the expedition gets the necessary permits for next year’s field season. Cooperation with BRG might give opportunities for ARCEx researchers to access more remote Arctic areas. Jan Inge also used the opportunity to spend an extra day discussing with BGR colleagues their work in the northern Barents and on the northern Barents Sea margin/Nansen Basin within their PANORAMA project.
