The stratified free surface Princeton Model is used to analyse dynamics in the Danish Straits, which connect the Baltic with the North Sea, Two basic experiments were done, The first one is the density-driven and the second one is the forced Baltic experiments. Buoyancy-driven circulation produces bi-directional flow in the Danish Straits with the fresh layer moving north above the southward flowing deeper layer, This circulation alone can not supply the transport required for a renewal of the deep Baltic bottom water. The thermohaline circulation loses its two-layer character with barotropic forcing. Unidirectional flow permits larger transport of volume and salt than bidirectional flow in the straits. The straits are geostrophically controlled, On the other hand the combination of Belt and Sound flows supply more transport through the Belt and the Sound for the inflow and the outflow case respectively. The model results are suited for comparison with laboratory and field studies, Particularly the dense rotating water in the Arkona basins can be explained with the processes over a sill, The inflowing water forms a dome-like feature in the basin after passing the sill.
