Start Port/Location: Dutch Harbor, AK

End Port/Location: Dutch Harbor, AK

Start Date: 2013-10-05

End Date: 2013-10-30

Equipment Used: GPS (wh), HYPACK, Sensors - other mooring, Temperature and salinity, Digital camera, Cavity Ring-Down Spectroscopy (CRDS)

Information to be Derived: Time series data;Samples and chemical analysis;Laboratory sensor data;

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.

Notes: Cavity Ring Down Spectrometer (CRDS) equipment was used for measuring methane and carbon dioxide. Additionally, collected weather data and water samples.
