Methane and carbon dioxide concentration data, environmental data, and calculations used to determine sea-air flux on the northern Greenland margin
Determining how much methane and carbon dioxide cross the sea-air interface is critical when assessing marine greenhouse gas fluxes. This assessment is particularly important on Arctic Ocean continental margins, where rapid climate change is thawing glacial ice and permafrost; reducing sea ice cover; and changing water temperatures, salinities, nutrient loads, and ocean currents. This dataset was collected in the Sherard Osborn Fjord and adjacent areas of the Nares Strait and Lincoln Sea on the northern Greenland margin during the 2019 Ryder Expedition (known as SWEDARCTIC Ryder 2019), which is also identified as U.S. Geological Survey (USGS) Coastal and Marine Hazards and Resources Program Field Activity 2019-042-FA. The University of Stockholm led the expedition aboard the Swedish icebreaker Oden (IB Oden), in collaboration with the University of New Hampshire and the USGS. The dataset contains 30-second interpolated methane and carbon dioxide concentrations in near-surface seawater and the atmospheric marine boundary layer and provides the calculations used to determine the sea-air flux. The dataset also contains environmental data, including seawater salinity, wind speed, water and air temperatures, water depth, seawater pH, seawater dissolved oxygen, seawater fluorescent dissolved organic matter, seawater oxidation-reduction potential, seawater phycoerythrin, and seawater chlorophyll.
