Arctic Ocean 2016 - Dissolved Gaseous Elemental Mercury in Surface Seawater

This dataset contains data collected during the Canadian-Swedish expedition Arctic Ocean 2016. The research cruise took place August through September 2016, using the icebreaker Oden.

The bow water system was used to pump seawater into the wetlab where the water was purged with clean air, releasing dissolved gaseous elemental mercury (DGM) into the outgoing air. An opposite flow extractor was used for the purging and a Tekran 2537A cold vapor atomic flourescence spectrometer was used for the detection of elemental mercury in the outgoing air. The data can be used to calculate the flux of elemental mercury from sea surfaces in the Arctic and to monitor the concentrations of mercury in the Arctic marine environment. Data include: Dissolved gaseous elemental mercury in surface seawater
