Temperature rise together with resultant ice cover retreat in Svalbard, changes in hydrology and geomorphology of fjords and coastal waters is presented as forming force for the marine habitats. Satellite data show increase of habitat complexity following the tidal glaciers retreat and emergence of new (315 km) and complex shoreline. Most evident changes occur in the inner-fjord settings of the west coast of archipelago, while habitats of exposed marine shores and eastern sector of Svalbard remains little changed. It is hypothesized, that decrease in ice cover opens more space for life compared to the cold period.
