Baltic Sea

Basin 55.9 ◦ N. From there the bottom water then enters the EGB over its eastern ank, arriving
rst at the SE mooring. The average from model simulations calculated deep circulation in
the EGB (visible in Fig. 4.18) conrms the pathway that emerged from the current meter
observations. Dense deep water enters the EGB over the eastern ank is then deected to the
right by the Coriolis force and travels round the deep boundary inside the basin in a cyclonic
circulation.
Temperature, salinity, density, depth and current data (u and v) were extracted as 5-day means
for three selected transects over a period of 7 years (2002 to 2009). The data are expected
to provide answers on how much water passes each transect and how much volume and salt
is transported through each section on its way to the EGB.
Modelled volume transports (of 5-day mean current values) through all three sections marked
in Fig. 4.18 are displayed in Fig. 4.19 with the Stolpe Channel's eastward transport at 17.5 ◦ E
in black, the Gdansk Basin's southward transport at 55 ◦ N in blue and the Hoburg Channel's
northward transport at 56 ◦ N in red. Only the relevant transport components, important for the
transports in the deep Baltic Proper, are investigated in these gures. In Fig. 4.19 A transports
between 2002 and 2009 are displayed, whereas Fig. 4.19 B only shows the time period between
