Stephen Gustav Kohler
About
Stephen works on the biogeochemical cycle of mercury in the Arctic Ocean.
Research
Seasonal concentrations, distributions, and transformation of marine mercury in the Barents Sea and Arctic Ocean.
The Nansen Legacy
"The Nansen Legacy is a novel and holistic Arctic research project providing integrated scientific knowledge on the rapidly changing marine climate and ecosystem."
BEST-Siberian
"BEST-Siberian aims to provide data and knowledge on the environmental and ecological risks due to increasing mobility and transformation of bioessential and toxic trace elements on the Siberian continental shelf under permafrost thawing."
