    What corrections were made to the CO2 concentration data prior to reporting it: 1) xCO2 corrected for pressure and temperature fluctuations during measurements 2) xCO2 corrected for dilution and pressure broadening due to water vapor 3) values averaged over 1 minute 4) xCO2 converted to fCO2 using measured atmospheric pressure and water vapor pressure at equil. temp 5) fCO2 at equil. temp. converted to in-situ temp.(fCO2 is=fCO2 eq* exp(0.0423* T)) Depth of sea water intake (in m): approx. 5.8 m below sea level ("moon pool") location of air intake: near the "monkeys island"(20 m above sea level)
