Measurements of pCO2 and turbulence from an autonomous drifting buoy in July 2017 in the Norwegian fjords and adjacent North Atlantic waters during cruise HE491, links to files

Data from autonomous, drifting buoy with a floating chamber to measure air-sea CO2 fluxes and gas transfer velocities (k) with high temporal and spatial resolution. The buoy is equipped with a sensor to measure aqueous and atmospheric pCO2, and to monitor the increase or loss of CO2 inside the chamb...

Description
Summary:Data from autonomous, drifting buoy with a floating chamber to measure air-sea CO2 fluxes and gas transfer velocities (k) with high temporal and spatial resolution. The buoy is equipped with a sensor to measure aqueous and atmospheric pCO2, and to monitor the increase or loss of CO2 inside the chamber. One complete cycle including two chamber measurements last 70 minutes. The buoy can be deployed for more than 15 hours, and at wind speeds of up to 10 m/s. Floating chambers are known to overestimate fluxes due to the creation of additional turbulence at the water surface. We check that by measuring turbulence with two Acoustic Doppler Velocimeter, one directly underneath the center of the floating chamber (equipped with an inertial motion unit) and the other one positioned sideways to measure turbulence outside the perimeter of the buoy. To control the conditions below the floating chamber, a sensor which measures temperature, pressure and humidity was installed inside the chamber. : Headers/units:GPS-data:Column A: Number of measurementColumn B and D: DateColumn C and E: Time UTCColumn F: Latitude [°]Column G: Latitude: N = North, S = SouthColumn H: Longitude [°]Column I: Longitude: E = east, W = westColumn J and K: We do not know, not relevantTPH-sensor (UNT330C_yyyymmdd.csv)NO.: Number of measurementDateTime: Date and Time (yyyy-mm-dd HH:mm:ss)°C: Temperature [ degree C]%RH: Relative humidity [%]hPa,= Pressure [hPa]DP, = Dew Point [degree celsius]°F = Temperature [degree Fahrenheit]
