Ran BOG Line, many days at Station M, BOG Line.

CW increased Eco Puck sampling to 10 min, data look much better :)

O2 data are ~30-40 umol/kg low compared to nearby M1, despite T & S agreeing very well at those same times; this has been the case for several deployments now and we have not had a chance yet to test the wgTiny O2 sensor in the tank. T-vs-O2 plot has a relatively tight, linear relationship as would be expected, but it deviates from this at higher T, when at Station M. During this time, O2 has several quick deviations from the general temporal trend where O2 drops quickly to ~100 umol/kg and then quickly recovers. These questionable data near Station M have been removed. Later, near BOG Line, low (100 umol/kg) and fluctuating O2 corresponded with fluctuations in T and S, these are assumed 'real.' Advised to use caution with the O2 data.

Low S ~31 near Moss Landing, likely 'real' and an artifact of recent rains, similar to previous deployment.

pCO2w is within ~20 ppm of M1, not as close agreement as last deployment, but the range is also greater this deployment, due to early-season upwelling, pCO2w of up to 700 ppm at wgTiny. pCO2a is within 3 ppm of M1, very good. pH is generally within 0.05 of nearby M1 and tends low of M1. The M1 pH sensor was recently swapped and seems to be accurate so far. The wgTiny pH sensor seems to be doing fine, although it has been 2 years since last calibration. We will re-calibrate prior to next deployment. T-vs-pH plot has a relatively tight, linear relationship, but this deviates while near Station M (gradual warming but ~constant pH). These data are likely OK. pH-vs-pCO2w plot looks pretty spot-on, perhaps pH is a bit (~0.02) lower than expected (which would agree with M1 assessment). As is typical, the first pH data point after payload turned on is low, this has been removed.

BB data look good.

Air T and p data look good.
