Lake Joyce is in the Pearse Valley, a westward extension of the Taylor Valley next to the Taylor Glacier and fed by the meltwater of the glacier. Lake Joyce is one of the smaller Dry Valley lakes. It is perennially ice-covered and the ice is about five meters thick and the ice is not smooth as known from lakes in Europe. The ice is rugged due to irregular freeze-thawing of the top-layer of the ice and deposition of soil from the surrounding hills by the wind.
Lake Joyce and Taylor Glacier with research tents
Research tents on Lake Joyce ice
As the lake is ice-covered samples are collected through diving. The diving is done by three members of our team that are very experienced scientific divers. In order to directly process our samples we had two tents on the ice next to the dive hole.
