Research Work

My research projects refer to the development of new methods of the efficient, long-term observation of processes in the sea. The work covers the range starting from hydro-acoustic methods and instruments, e.g., to the quantification of bubble streams, about optical methods for measuring basic parameters in the water column up to mobile and stationary observation platforms. In the following topical works are listed:

Ocean Observatories

Long time stations for the continuous observation of changes of the marine environment receive in the course of the investigation of the effects of the climate change a growing attention. At the European level there are a number of initiatives (ESONET, EMSO) that aim at the establishment and crosslinking of long time ocean observing stations. The technical implementation poses special challenges, because suitable infrastructures have a high degree of complexity. A big number (~ 100) of underwater sensors and instruments continuously send data to a central station which has to provide a reliable communication link to a land station. The architecture of the data processing and long time data storage must follow principles that allow for a quick access and a wide use.

Wheeled Underwater Vehicle CMOVE

The underwater vehicle CMOVE serves as a platform for measurements close to the seabed. CMOVE is of particular interest to carry out measurements of the microbial activity in the surface sediment and for this microelectrodes are used. Within the scope of the alliance HGF ROBEX it is planned to utilise the concept of CMOVE for geophysical measurements in the seabed. For this purpose a group of CMOVE vehicles will be synchronically piloted across the seabed where the positions of the single vehicles have to be recorded exactly.
