Both the mouth of the Atran and which sea flow into Kattegat?
Kattegat The Kattegat (] ; Swedish: "Kattegatt" , ] ) is a 30000 km2 sea area bounded by the Jutlandic peninsula in the west, the Danish straits islands of Denmark to the south and the provinces of Västergötland, Scania, Halland and Bohuslän in Sweden in the east. The Baltic Sea drains into the Kattegat through the Danish Straits. The sea area is a continuation of the Skagerrak and may be seen as a bay of the Baltic Sea or the North Sea or, as in traditional Scandinavian usage, neither of these.
Little Belt (ship) At least six vessels, including two belonging to the British Royal Navy, have borne the name Little Belt, a translation from the Danish of "Lillebælt", the name of the strait that separates Funen from the Danish mainland and that links the Kattegat to the Baltic Sea. The merchant vessels and the second Royal Navy vessel were named to commemorate HMS "Little Belt" , which was one of the protagonists in the Little Belt Affair, or perhaps the affair itself.
