Localised Enhanced Sedimentation from Icebergs in a Proglacial Lake in Briksdal, Norway

ABSTRACT

Studies of the ice-contact proglacial Briksdal Lake in Norway have demonstrated that drifting icebergs congregate in a well-defined zone near the outlet. Deposition of the englacial debris from decaying icebergs is concentrated within this area forming a shallow underwater shelf and associated beach. It is suggested that this process may have characterized former proglacial lakes.
