BOG Lines, Station M, BEDS work, more BOG Lines... A new pH electrode and ECO-Puck were installed for this mission, both performed very well. The old CTD was calibrated and installed for this deployment, data look good, including O2! pCO2a is within 5 ppm of M1. pCO2w is generally within ~20 ppm of M1, both signals are pretty variable indicating natural variability. All MET air temp data were removed.
