摘要:
The mean sea level along the coasts of the Skagerrak, the Kattegat, and the Danish Straits—i.e., the transition area between the North Sea and the Baltic Sea—has been computed geodetically. The basis consists of mean sea level data from Denmark, Norway, and Sweden in various more or less inappropriate height systems. These are transformed and unified into a common height system relevant for oceanographic purposes to show the deviation of the mean sea level (1960) from the mean geoid, with Normaal Amsterdams Peil (NAP) as zero. The geodetically determined mean sea surface is compared with oceanographic model results for parts of the area. Among other findings, the outflow of low‐salinity water from the Baltic Sea, as well as its separation from high‐salinity North Sea water along the Kattegat‐Skagerrak front are clearly revealed.
