Kattegat

The Kattegat extends across 30,000 square kilometers of water between the Jutland peninsula and the Swedish provinces of Bohuslän, Västergötland, Halland and Scania.

The Kattegat remained the single maritime route to enter and exit the Baltic region until 1784, when the construction of the Eider Canal introduced an alternative path.

Danish authorities collected Sound dues from passing vessels through the Øresund starting in 1429, while Copenhagen provided maritime services and protection for merchant ships.

Modern navigation in the Kattegat relies on artificial seabed channels, extensive reef dredging operations, and a network of light signals to guide maritime traffic.

The water composition in the Kattegat forms two distinct layers, with the upper section containing 18-26% salinity and the lower section reaching 32-34% below 15 meters depth.
