Notes on the Oceanography of d'Iberville Fiord

The oceanography of a small arctic fiord has been studied over a period of three years. The shallow water structure is determined by convection in the fiord, as is shown by temperature-time series and budget studies. The fiord contains temperature inversions at shallow depths, which have been present in observations over several years. The deeper water structure is determined by the sill across the fiord mouth and similar sills in Nansen Sound that restrict free access at depth of water layers from the Arctic Ocean.
