The oxygen products from this instrument are suspect, due to errors during vendor calibration. Until a correction can be applied, the oxygen data during this time range should not be used.

An anomalous drop in conductivity values from this sensor was observed, beginning in Dec. 2018. Scientific and technical analysis determined that it was likely due to a clogged conductivity cell. Power to the CTD pump was cycled on 2019-01-14, which appeared to resolve the issue and bring conductivity back into a reasonable range. Conductivity, salinity, density and salinity-corrected DO data products from this sensor should be considered suspect during this time range. A subsequent drop in conductivity values on 2019-01-18 indicates the issue may have reoccurred, so investigation is ongoing.
