The Kattegat Sea is a body of water located between the eastern coast of Denmark and the western coast of Sweden. It connects to the Skagerrak, which leads to the North Sea, and is an important route for maritime traffic in Northern Europe. The sea is characterized by its relatively shallow waters and numerous islands. The Kattegat is known for its rich marine life and diverse ecosystems, making it a vital area for fishing and biodiversity. It also plays a significant role in the climate and weather patterns of the surrounding regions, influencing both Denmark and Sweden.
