A "Bodden" is a type of shallow coastal lagoon found primarily in the northeastern part of Germany, particularly in the Baltic Sea region. These lagoons are characterized by their brackish water, which is a mix of saltwater and freshwater. Bodden areas are often rich in biodiversity, providing habitats for various species of fish, birds, and plants. The term "Bodden" is derived from the Slavic word for "bay." These lagoons are typically formed by the action of waves and currents, creating sheltered areas along the coastline. They play an important role in local ecosystems and are often used for fishing and recreational activities.
