Application of satellite data to Baltic Sea
Sea Surface Temperature of the Baltic Sea
Sea Surface Temperature is a key parameter for oceanographic and atmospheric investigations because it is in direct relationship to heat, impulse and gas exchange in the ocean. The Advanced Very High Resoltuion Radiometer (AVHRR) on NOAA (National Oceanic and Atmospheric Administration) -weather satellites measures the water sea surface temperature in the thermal infrared spectral region of the electromagnetic spectrum. The Federal Maritime and Hydrographic Agency (BSH) in Hamburg operates a receiving station and collects NOAA-AVHRR data for the North and Baltic Sea. After data processing, calculated SST as grey scale values are provided to IOW for application in Baltic Sea research. The remote sensing group generates colorized SST-maps for the Baltic Sea.
Main topics of SSTapplications in Baltic Sea research are support of monitoring program, investigation of dynamical processes and coastal discharge, and climatologic analyses.
The winter 2010/2011 started early with snow and ice in large parts of europe. Satellite data allow the observation of ice development at sea. For the operators of our MARNET stations in the western Baltic Sea we pursue the ice development, in order to be able to take in time safeguards.
Cyanobacteria bloom in the Baltic Sea
Satellite sensors of ocean color designed to detect algae blooms from space. Data of Medium Resolution Imaging Spectrometer (MERIS) and Moderate Resolution Imaging Spectroradiometer (MODIS) are applied for the Baltic Sea algae blooms. The IOW monitore the cyanobacteria bloom in summer and provide results for Landesamt für Umwelt, Naturschutz und Geologie (LUNG)
