From Wikipedia, the free encyclopedia
Overdeepening is a characteristic feature of glacially formed fjords.
Fjords are found in locations where current or past glaciation extended below current sea level. A fjord is formed when a glacier downwastes, or melts faster than it is moving, after carving its typical U-shaped valley, and the sea fills the resulting valley floor. This forms a narrow, steep sided inlet (plunging up to 1900 m or 6300 ft below sea level) connected to the sea. Overdeepening of the glacier bed is common, which when combined with the terminal moraine often deposited at the fjord's entrance, usually results in shallower water at the neck of the fjord than in the main body of the fjord. Overdeepenings form near glacier heads or anywhere along the length of a glacier, but are prominent in downglacier reaches (i.e., areas where the glacier dropped significantly tend to be overdeepened at the base of the ice descent).
