The Water Lab


When water samplers are pulled from the lake, they are brought here. Scientists perform experiments, view samples in the microscope, and preserve water for later chemical and biological analysis at home.

The team builds snow walls around their tents to try to control drifting snow when the wind picks up. The walls only delay the inevitable - as the interior of the tent heats from the sun, they sink in the ice and must be dug out every couple weeks. The intense UV rays from the sun also make the material brittle and prone to tears. High winds can quickly fill a tent with snow, even through a small tear!

Sediment Lab


When sediments samples are collected from the lake, they are brought here. Some analysis and experiments can be done in the field, but much of the sediment and the long cores are packed and transported back home for analysis.
