Much of my research interests focus around the oceanic carbon cycle, which includes the transformation of carbon, the fluxes within the ocean, the air-sea fluxes and the oceanic sequestering of anthropogenic carbon dioxide. These studies involve high latitude oceans, at both hemispheres, and the waters around Sweden . Of special interest have also been the investigation of the Arctic Ocean , and the use of chemical tracers to understand "how this ocean works".
Parallel to the above investigations a continuous development of analytical chemical tools for the investigation of the oceans has been performed.
