Skagerrak

Skagerrak, strait, between the southern coast of Norway and the Jutland Peninsula of Denmark. Together with the Kattegat Strait, it connects the North Sea with the Baltic Sea. About 240 km (150 mi) long and from 120 to 145 km (75 to 90 mi) wide, the Skagerrak is shallow near Jutland (less than 50 m/165 ft) but deepens near the Norwegian coast (more than 500 m/1,650 ft). The strait is subject to violent storms. During World War I the naval Battle of Jutland was fought in the Skagerrak.
