Tasks of the Marine Monitoring
Monitoring of physical and biogeochemical variables,
mainly in German coastal waters
Monitoring of the current state of the physical properties of
sea water
Monitoring of changes of marine climate
Support of marine services (i.e. sea ice service, water level
and storm surge forecast service )
Support of operational models
Calibration of remote sensing data
Basics for the Offshore-Industry

FINO
Oceanographic Measurements
Goals:
Basic information about local met-ocean conditions
Long-term observation of main met-ocean parameters
Registration of boundary conditions for atmospheric and
hydrodynamic models
Basic input for access and logistics
Identification of “Extrem Events”
Basics for load calculations

MARNET - Boundary Conditions
MARNET-stations:
Positions off the coast
rough weather conditions
access by ship only
permanent operation
real time data
General Trends:
fast availability of data (world-wide),
preferably in real time ==> Internet
decreasing resources
