Bacterial and archaeal lipids trace chemo(auto)trophy along the redoxcline in Vancouver Island fjords
Kusch, Stephanie; Wakeham, Stuart G.; Dildar, Nadia; Zhu, Chun; Sepúlveda, Julio (Geobiology, 2021-05-07)Abstract Marine oxygen minimum zones play a crucial role in the global oceanic carbon, nitrogen, and sulfur cycles as they harbor microbial communities that are adapted to the water column chemistry and redox zonation, and ... -
Increased petrogenic and biospheric organic carbon burial in sub‐Antarctic fjord sediments in response to recent glacier retreat
Berg, Sonja; Jivcov, Sandra; Kusch, Stephanie; Kuhn, Gerhard; White, Duanne; Bohrmann, Gerhard; Melles, Martin; Rethemeyer, Janet (Limnology and Oceanography, 2021-10-28)Fjords are recognized as hotspots of organic carbon (OC) burial in the coastal ocean. In fjords with glaciated catchments, glacier discharge carries large amounts of suspended matter. This sedimentary load includes OC from ... -
Last Glacial central Mediterranean hydrology inferred from Lake Trasimeno’s (Italy) calcium carbonate geochemistry
Francke, Alexander; Lacey, Jack H.; Marchegiano, Marta; Wagner, Bernd; Ariztegui, Daniel; Zanchetta, Giovanni; Kusch, Stephanie; Ufer, Kristian; Baneschi, Ilaria; Knödgen, Katharina (Boreas, 2021-09-02)There is still a paucity of hydrological data explaining the relationship between (rapid, millennial‐scale) climate forcing and Mediterranean rainfall since the Last Glacial. We show that distinct lake‐level fluctuations ... -
Permafrost Organic Carbon Turnover and Export Into a High‐Arctic Fjord: A Case Study From Svalbard Using Compound‐specific 14C Analysis
Kusch, Stephanie; Rethemeyer, Janet; Ransby, Daniela; Mollenhauer, Gesine (Journal of Geophysical Research: Biogeosciences, 2021-03-14)In a warming climate, thawing permafrost soils in the circumpolar Arctic region are subject to enhanced microbial turnover as well as mass mobilization and other erosion processes. High‐Arctic settings such as Svalbard are ...
