Summary of Activity and Data Gathered: Methane and carbon dioxide in air (3 elevations above the ocean: 16 or 35 feet, 50 feet, and 109 feet) and surface water were measured during transits, transects, and while on CTD / mooring station in the Arctic Ocean. Additionally samples were collected vertically from CTD casts and analyzed for methane. Atmospheric measurements (wind speed, direction, temperature) were made by 3 AirMars mounted at 3 different elevations above the ocean. Temperature, conductivity, dissolved oxygen, salinity, pH, and ORP measurements were made by a YSI water parameter sonde.
