The effects of global climate change are particularly pronounced in the Arctic and yield fundamental environmental changes as a consequence. The rising temperature causes higher water temperatures in summer and especially for melting of Arctic glaciers, the freshwater input inevitably leads to changes in Arctic fjord systems. Therefore, the proposed study has two main objectives to address: (1) change in the biological diversity of the plankton communities (zoo-, phyto- and bacterioplankton) along salinity and temperature gradients in Arctic fjords, and (2) the potential occurrence of toxic phytoplankton species in the Svalbard fjords due to the changing climatic conditions. Accordingly, 5 different fjord systems in the north and west of Svalbard will be studied (van Mijenfjorden, Wijdefjorden, Woodfjorden, Kongsfjorden, Isfjorden); of those only Kongsfjorden and Issfjorden are relative good studied. However, these fjords are differentially strongly influenced by Arctic and Atlantic water and differ further in their size, the influx of glacial freshwater and the annual ice-cover.
