Hodgson Lake

Hodgson Lake is a subglacial lake in Antarctica, first discovered in 2000 and officially described in 2009. The lake is situated on southern Alexander Island, west of the Antarctic Peninsula, at approximately 72°S latitude and 68°W longitude.

The UK Antarctic Place-Names Committee named Lake Hodgson after Dominic Hodgson, a British Antarctic Survey geoscientist and lead author of the discovery reports.

Hodgson Lake is about long by wide and is about deep. The lake is covered by of ice and has been isolated from the outside world for the past 30,000 to 90,000 years.

Hodgson Lake was formed under the ice, when the base of the ice sheet melt because of the pressure from the ice cap above and the heat released by the rocks from below. The lake is an ultra-oligotrophic lake, with very low nutrient content and very low productivity.

There is no detectable life living in Hodgson Lake.
