The Sea Ice Team’s biggest question is what kinds of gases are given off to the atmosphere by the algae and bacteria living in the sea ice. Dr. Tish Yager created the design for these custom glass chambers. A 10cm long piece of the 14cm diameter ice core is placed into the airtight chambers as soon as it is cut from the sea ice. The chambers are then placed under bright lights in a refrigerated lab so that the algae and bacteria continue to live and give off gases. The gases are then collected through the valves at the top of the chambers. Aboard the icebreaker Oden.
