Figure 4.18: Propagation of the deep water in the bottom boundary layer (black arrows) and mean salinity
distribution for the Baltic Proper, simulated with MOM4. T, S, depth and currents were extracted as
5-day means for 3 selected transects (red lines). White triangles represent mooring positions.
May 2006 and the end of March 2007. All transports were calculated for salinities greaterthan-or-equal
12 g/kg salt, under the assumption that salt less than 12 g/kg salt is not able to
travel beyond the Stolpe Channel as deep density currents. This assumption is also supported
by the over 87 days time averaged salinity in Fig. 4.18, where the average salinity entering the
deep EGB is higher than 12 g/kg salt. The southward volume transport in Fig. 4.19 A reveals
rhythmic peaks in transports appearing on an annual basis, around autumn/winter each year.
The rst peak was recognised on 11 October 2002 and the last 6 March 2009; every peak
