Origin

Narrative

The basin is a near circular body of water tenuously connected to Long Fjord, in the Vestfold Hills. It is adjacent to Partizan Island. The connection between the basin and the fjord is approximately 40 m wide and is very shallow. The ice in the basin during winter is significantly above that of the fjord suggesting that no water exchange occurs between the two during winter. The basin is approximately 400 m in diameter. The maximum recorded depth is 13 m. The salinity of the water ranges from above seawater (circa 50gL-1) at the surface to approximately 120gL-1 at 13 m. Basin water is anoxic beneath 6 m. The basin has been stratified since at least 1991, when the first known sampling occurred and should thus be considered meromictic. The basin is therefore similar to Lake Burton and Bayly Basin in being permanently stratified while maintaining a seasonal connection to marine waters. The basin is named for Patrick Deprez who wintered at Davis in 1984 as a chemical limnologist. In this role he contributed significantly to the knowledge of the lakes of the Vestfold Hills.
