A modified chamber was designed for in situ measurement of carbon uptake of micro-algae growing on the underside of sea ice. The chamber, operated by SCUBA divers, accommodates a wider range of ice conditions, has better holding capability, and reduces sample loss during retrieval.Key words: Arctic Ocean, sea ice algae, primary productivity
