Processes and sensing of marine interfaces
The group Marine Interfaces aims for a better understanding of biogeochemical processes in the sea surface and upper ocean, e.g. the upper 1-2 meters. The sea surfaces is in direct contact with the atmosphere, and knowledge of the chemical, biological and physical nature of the sea surface is essential
- for a better understanding of climate-relevant air-sea interactions such as the exchange of gases, heat and particles (aerosols).
- as an unique habitat of photochemical and microbial driven biogeochemical processes.
- for proper interpretation of data from remote sensing systems.
The group is particularly focussed on the sea-surface microlayer (SML), natural organic films covering the ocean`s surface to a wide extent. With a typical thickness of 40-100 µm, the SML has physicochemical and biological properties that are measurably distinct from underlying waters. Because of its unique position at the air-sea interface, the SML is central to a range of global biogeochemical and climate-related processes.
