Biodiversity and Fluxes in Glacial Arctic Fjords (BIODAFF) is a project to study the effects of seasonal fluctuations in salinity, turbidity and sedimentation rates in the glacial fjords on Svalvard on how the diversity of ice flora and fauna is structured by stress gradients and the abiotic factors of the ice habitat.

Also studied will be the zonation of macrobenthic organisms on hard bottom substrates and how this zonation changes longitudinally in the fjord against the general stress gradients. The work will involve several diving transects from inner to outer fjord. This project began in 1996 and is being performed by the Norwegian Polar Institute under their leadership.
