Research Focus
The environmental conditions in the sea change constantly both in the short- and long-term. In order to detect these processes, the research group Marine Sensor Systems explores and develops innovative methods and sensors that can be operated on-site at sea. The scientists identify key variables of coastal regions and shelf seas and integrate them into observation systems. One focus is on measuring methods based on optical and acoustic principles.
Thematic Focus
Design innovative and affordable sensors technologies for sustainable interdisciplinary monitoring of the natural environment.
Automate sensors for easy use as well as integration on in-water, fixed, ship based and airborne platforms.
Observe biogeochemical and physical Essential Ocean Variables in all aquatic environments from open ocean to fjords, shelf seas and estuarine systems

- ocean colour (inherent, apparent optical properties)
- plastic litter (virgin, washed ashore and ocean harvested of all sizes)
- imaging of planktonic organisms
