Comment:
Turbulence and pCO2 data from autonomous, drifting buoy with a floating chamber that will allow us to calculate 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. A complete cycle lasts 40 minutes, and after flushing the chamber a new cycle is initiated. The buoy can be deployed for more than 12 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 correct fluxes by measuring turbulence with two Acoustic Doppler Velocimeter: one directly underneath the center of the floating chamber and the other one positioned sideways to measure turbulence outside the perimeter of the buoy.
Data available, name and format:
Iymmdd0x.VEC: data from IMU ADV directly from Nortek download.
Yymmdd0x.vec: data from SLAVE ADV directly from Nortek download.
AyymmddA.txt: data from SubCtech, CO2 data from seawater (AnalyzerStat = 5), Air (AnalyzerStat = 21) and inside the bowl (AnalyzerStat = 18).
Export_yyyy-mm-dd.csv: data from GPS attached to buoy.
UNT330C_yyyymmdd.csv: data from temperature, pressure and humidity data inside the bowl.
Notes:
2015-08-03: No CO2 data. ADVs were named as 2015-08-03 but follow measurements until 2015-08-04. I renamed to submit to PANGAEA as 2015-08-04 to avoid confusion.
2015-08-04: No GPS available for buoy but as catamaran was always close by I used this.
2015-08-09: No temperature, Pressure and humidity data.
Except for day 2015-07-30, the pCO2 need a correction of: pCO2 (real) =(pCO2(file)+142.6)/0.71)
