CE02SHSM-SBD12-04-PCO2AA000 Method: recovered_host Stream: pco2a_a_dcl_instrument_water_recovered |

A vendor error in assembly pinched closed an internal tube carrying the surface air stream into the sample volume, resulting in an erroneous measurement. Users should not use the PCO2A air measurement for the Spring 2018 deployment (deployment 07), nor the associated sea-air pCO2 flux estimate.

CO2 sensor internal to the instrument has failed. Sensor started reporting erroneous values for the CO2 measurements and then flat-lined to 0.
