Measurement of pH, conductivity and oxygen at pond (unofficial name Egypt Pond) in Pyramid Trough with view into the valley.

Assembly of ice corer. Cryoconite holes were ice covered and a hole has to be cored in order to sample water and sediment.

Drilling a hole into cryoconite on Koettlitz Glacier for water and sediment sampling for water chemistry and microbial diversity analysis using molecular tools.

Before walking onto the Koettlitz Glacier, team members are putting on crampons for safe walking on the ice at the ice core moraine.

Sampling of water and sediment at pond on ice cor moraine near Koettlitz Glacier. A hole had to be made using an ice axe in order to carry out sampling.

Measurement of pH, conductivity and oxygen in supraglacial pond on the ice near Miers Valley.

Sampling of microbial mats and sediment on supraglacial pond on the Darwin Glacier.

Water and microbial mat sampling of a meltwater pond on the McMurdo Ice Shelf near Bratina Island for water chemistry and molecular microbial diversity analysis.
