Christoph Böttner serves as an Assistant Professor of Marine Seismic Sedimentology at Stockholm University's Department of Geological Sciences. He is an active member of IGV's Marine Geology group, which studies the geology and history of the oceans through analyses of marine sediment archives and submarine landforms.
Dr. Böttner is a marine geoscientist with expertise in marine geophysics and marine geology. His research focuses on fluid flow systems, sediment transport, and the influence of climatic changes on marine environments. He has advanced experience in the collection, processing, and interpretation of marine acoustic data, which he combines with interdisciplinary datasets to address critical geological questions.
His research spans several critical areas including fluid flow system research for safe carbon capture and storage operations, marine geohazards and quantitative geomorphology (studying subaqueous landslides, volcanic flank collapses, and active faulting), greenhouse gas emissions from Arctic marine sources, and the interface between hydrosphere and geosphere. Notably, his work on submarine gravity flows has revealed that these phenomena can reach devastating velocities up to 19 m/s with volumes exceeding 150 km³, carrying substantial amounts of carbon, nutrients, and pollutants into the deep sea.
Dr. Böttner's research on pockmarks and fluid flow expressions on the seafloor (>50,000 pockmarks analyzed in the German Bight) is particularly relevant for offshore wind farms and submarine cable infrastructure. His work on methane emissions from marine sediments addresses critical climate change questions, as methane has twenty-eight times higher global warming potential than CO2 and currently contributes to about a third of global warming.
His research group actively investigates sedimentary systems at the seafloor interface, including meltwater plumes, contourites, and sediment waves, which represent one of the most abundant bedforms on our planet given that oceans cover two-thirds of Earth's surface.
