Deep marine sediments
Unravelling the deep biosphere
Main content
The deep biosphere remains poorly characterized, yet imposes significant controls on the geochemistry of the Earth鈥檚 surface and deep subsurface.
Our group combines geochemistry with microbiological techniques to study the microbial ecosystems in deep marine sediment cores from the Norwegian-Greenland sea. We study sediments that are influenced by hydrothermal activity and deep marine pelagic sediments and use on board and on land laboratories for geochemical characterization of pore fluids. Microbiological analyses are done in close collaboration with our colleagues from the Institute for Biology.
This research is done under the BFS project awarded to Dr. Steffen Leth J酶rgensen and Work Package 5 of the K.G. Jebsen Centre for Deep Sea Research 鈥淕eochemical energy landscapes and life鈥�.听听
