CCGS Amundsen underway gas measurements, 2018-2019

These underway, ship-based data, were collected using autonomous gas analyzers to observe spatial and temporal trends in surface dissolved gas (O2, Ar and N2) distributions throughout the waters of the pan-Canadian Arctic (including Labrador Sea, Davis Strait, Baffin Bay, and the Canadian Arctic Archipelago consisting of Lancaster Sound, Queen Maud Gulf, and the northern waters of Nares Strait and Kennedy Channel). Ultimately, these data will be combined with hydrographic observations to derive high spatial resolution estimates of surface waters net community production (i.e. photosynthesis minus respiration) over a multi-year period.
