Reserach Interests

The gradual recovery of the ozone layer is expected over the next decades due to the reduction of anthropogenic emissions of long-lived chlorofluorocarbons following the Montreal Protocol of 1987. The sources of marine very short-lived halocarbons ( e.g. of bromoform, CHBr3) and their influence on ozone, on the other hand, are increasing. We investigate the distribution and biogeochemical cycling of natural and anthropogenic halocarbons from various sources (phytoplankton, macro algae, disinfection processes) in the ocean and their air- sea exchange.Through seagoing measurements of the trace gases and in cooperation with biologists and earth-system modellers, regional and global, spatial and temporal data gaps are closed in order to clarify the oceanic contributions to future tropospheric and stratospheric ozone chemistry.
