Phytoplankton are responsible for releasing half of the world's oxygen and for removing large amounts of carbon dioxide from the surface waters. Nowadays, Arctic phytoplankton deserve special attention as they are living in waters with the most prominent climate change effect. The current thesis combines remote sensing, simulated and field data for the years 1998-2012, to investigate the seasonal cycle, variability and productivity of phytoplankton in the Greenland Sea. In addition to that, we study the link between phytoplankton and physical factors, such as sea ice concentration and thickness, water temperature and salinity.eninfo:eu-repo/semantics/openAccessphytoplanktonprimary productionsea icestratificationremote sensingice-ocean circulation modelprimary production modelArcticGreenland SeaFram Strait500 Naturwissenschaften und MathematikDissertationurn:nbn:de:gbv:46-00103817-16
