The concentrations of SO 4 2- , DN and DOC and ORP of overlying water in the duplicate Lower Martin Lake and Yellowknife Bay cores throughout the 30-day experiment. Each vertical grey line represents a new temperature treatment. The precision of SO 4 2- , DN, and DOC concentrations is estimated at < 10% based on RSD of three duplicates.
