Quick Summary

Landsort Deep is the greatest deep in the Baltic Sea, reaching a depth of 1,506 feet (459 meters). It is located off the southeast coast of Sweden, between Nyköping and the island of Gotland. The Baltic Sea itself is an arm of the North Atlantic Ocean, extending between the Scandinavian Peninsula and continental Europe. It is the largest expanse of brackish water globally and is relatively shallow, covering about 149,000 square miles (386,000 square km). The sea is characterized by distinct seasons, with cold winters and short, warm summers. Due to its nearly landlocked nature and shallow outlet, the Baltic Sea's waters are remarkably fresh.1
