Dr. Wolfgang Ebenhoeh 3. Abstract Die Untersuchung der marinen Primaerproduktion ist ein wichtiger Aspekt in der Erforschung des globalen Kohlenstoffkreislaufs. Licht ist eine der primaeren Voraussetzungen fuer Wachstum in pelagischen Oekosystemen. The investigation of marine primary production plays a key role in researching the global carbon cycle. Based on results from several cruises the hydrographical, biological and optical situation north of the Canary Islands is presented and compared with previous published results.
Light is a primary factor for growth in pelagic ecosystems.
It is shown that for different PAR descriptions there is only a small variability in annual primary production but a pronounced change in the vertical distribution of phytoplankton in the water column. By MMM-diss .
