Research focus of Marine Sensor Systems.
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/ key issues of Marine Sensor Systems.
‐ Multispectral sensors for biogeochemical parameters and marine pollutants
‐ Autonomous long-term sensor and observation systems
‐ Methods for quality assurance of time series data
‐ In situ imaging for detecting spatiotemporal distribution patterns of plankton and particles
‐ Description and quantification of biogeochemical and hydrodynamic exchange processes
Key to field based activities and data synthesis are setup and operation of a long-term reliable sensor system. Its data availability is necessary for the interpretation of ecosystem dynamics and changes in several contexts. Therefore, a central objective for WP 2 is the deployment of sensors and data loggers to assess relevant environmental parameters for a continuous recording in and around the experimental sites. Here, mainly the installation and maintenance of sensors and loggers will be conducted followed by data analyzing and quality control checks.
Data of the study site covers already a period of more than 3 years with seasonal and tidal dynamics as well as storm events and are available at PANGAEA® database (PANGAEA/BEFmate). Within DynaCom, the existing sensor network will be extended for a broader covering of abiotic parameters
Following abiotic parameters are covered within DynaCom SPZ-WP 2 respectively will follow soon:
Furthermore, a sensor hub is planned to be integrated into an experimental island, providing online access and visual information on central environmental conditions and the overall island status. Moreover, a mobile central field unit (10 ft. container) will be specified to build up nearby the experimental sites providing energy and network infrastructure for terrestrial sensor systems, and a central telemetry unit for online access and visual information. The container will offer space for in-field preparation of samples as well as storage possibilities for spare parts, fieldwork and maintenance stuff.
WP 2 is also involved in common objectives of SP Z, especially regarding technical foundations for experimentation and sampling:
- Maintenance of the experimental islands and plots
- Sampling infrastructure
- Providing formal permissions and training needed to access to experimental sites
