Ablation Lake
Ablation Lake is a proglacial tidal lake lying in Ablation Valley of Alexander Island, in the British Antarctic Territory. It is stratified with saline and fresh water and depths exceeding 380 feet.
The feature is dammed in the upper portion by ice that pushes into the lake from the adjacent George VI Ice Shelf.
The lake is named after Ablation Valley following British Antarctic Survey limnological research from 1973. The site lies within an Antarctic Specially Protected Area named 'Ablation Point – Ganymede Heights Antarctic Specially Protected Area'.[1]
The lake is up to 1,640 feet below the surface of the ice and has a sub-ice channel connecting it to George VI Sound, the channel separating Alexander Island from the mainland (Palmer Land).[2]
