A new measurement of CO2 eddy flux in the nearshore atmospheric surface layer

Fluxes of CO2 in the atmospheric surface layer have been measured at a shoreline site by the eddy correlation method using a new CO2 sensor with greater sensitivity than the ones used in earlier studies. In this experiment, preliminary to more extensive measurements at an offshore site, 13 upward and downward fluxes were observed to respond to differences in pCO2 between water and air. As in an earlier study, a negative correlation of CO2 flux was found with hourly change in wind speed.
