Soft bottom species richness and diversity as a function of depth and iceberg scour in Arctic glacial Kongsfjorden (Svalbard)
Macrozoobenthic soft-sediment communities inhabiting six depth zones of central Arctic Kongsfjorden were analysed comparatively using SCUBA-diving. 63 taxa were found, 30 of which had not been reported for Kongsfjorden and seven for Svalbard. Suspensivorous or surface and sub-surface detritivorous p...
