CE09OSSM-SBD12-04-PCO2AA000 Method: telemetered Stream: pco2a_a_dcl_instrument_air |
4/9/15, 1:30 PM | 9/25/15, 2:30 PM |
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 2015 deployment (deployment 01), nor the associated sea-air pCO2 flux estimate.

A HITL review of the data has found unusual, nonrealistic data during this time range. The data during this time range is marked as failed and users should avoid using this data in their analysis.

UPDATED, 2020-01-28: The QC flag for the air measurement has been reset to fail. Users should not use the PCO2A air measurement for the Spring 2018 deployment (deployment 0), nor the associated sea-air pCO2 flux estimate. *PCO2A air measurement for the Spring 2018 deployment is considered suspect. Recent investigations have indicated a vendor error in assembly may have pinched closed an internal tube carrying the surface air stream into the sample volume resulting in an erroneous measurement.
