Summary Information for Field Activity 2012-042-FA

Area of Operations: Beaufort and Chukchi Seas

Dates: October 05, 2012 to October 25, 2012

Chief scientist: Carolyn Ruppel

Objectives: To measure methane and carbon dioxide in the air and water of the Arctic Ocean.

Type of Activity: Sampling;Chukchi and Beaufort Seas

Information to be derived: Samples and chemical analysis;Laboratory sensor data;Physical property data;

Summary: Methane and carbon dioxide in air (3 elevations above the ocean: 35 feet, 50 feet, and 105 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.
