(Arneborg, Janzen, Liljebladh, Rippeth, Simpson,  Stigebrandt., Spatial Variability of Diapycnal Mixing and Turbulent Dissipation Rates in a Stagnant Fjord Basin, JPO, July 2004, pp. 1679-1691).

As part of the EU project OAERRE, observations of dissipation were made both spatially and temporally along the Gullmar Fjord (Sweden) over the course of three days in July-August 2001 to provide estimates of vertical exchanges and rates of mixing.  Two microstructure profilers were use in this study, the FLY and MSS profilers. Additionally,  moorings were placed at 4 positions along the fjord to gather current, temperature, salinity, and pressure measurements every 5 minutes for a month.  The mapping of dissipation rates indicates that dissipation in the deep basin is confined to areas just inside the sill. The majority of the dissipation in the fjord basin occurs in just 19% of the basin volume closest to the sill.  Half of the dissipation appears to occur in the bottom boundary layers at these most energetic stations, while the rest occurs in the stratified interior.
