UPDATED, 2019-01-15: After careful review, the original data product algorithm (pco2_pco2wat) for this sensor was found to contain an error that resulted in calculation of incorrect derived L1 pCO2 values. In consultation with the vendor, the algorithm has been corrected, verified, and uploaded to the OOI system. This update, effective 2019-01-10, applies to all deployments for this sensor. All derived L1 pCO2 data products generated prior to this date should be re-requested in order to ensure utilization of the correct algorithm. The updated algorithm can be viewed at https://github.com/oceanobservatories/ion-functions/blob/master/ion_functions/data/co2_functions.py. * Until further notice, derived L1 pCO2 data products from this sensor are incorrect and should not be used. A significant discrepancy has been uncovered between the pCO2 values from shipboard water samples vs. values calculated by OOI system, and the algorithms are under review: https://github.com/ooici/ion-functions/blob/master/ion_functions/data/co2_functions.py. To receive instant notification of updates to the code, add yourself as a watcher to the GitHub repository linked above. For further questions please email help@oceanobservatories.org.

The high voltage lines providing power to the MFN via the CVT for CE09OSSM-00004 shorted out on 2017-01-22 at 08:31 UTC. Sea state was high, but not unusual for this time of year. Disabled future power scheduling to the MFN and applied an override to disable the CVT. No further data will be logged from the instruments on the MFN. This affects:
On DCL35:
* ADCPS (had already failed upon deployment)
* PCO2W -- should continue to autosample
* PHSEN -- should continue to autosample
* PRESF -- should continue to autosample
* VEL3D -- should continue to autosample
On DCL37
* CTDBP (plus DOSTA) -- should continue to autosample
* OPTAA
* ZPLSC -- had stopped reporting data early on in deployment, may still be autosampling

The high voltage power supply providing power to the seafloor dataloggers and instrumentation failed for reasons unknown at this time. No further telemetered data will be available for this deployment.

Power to the seafloor sensors failed. With the exception of the VEL3D and OPTAA, the sensors on the seafloor platform should continue to autonomously sample for the remainder of deployment. Until we recover and redeploy the mooring in the spring of 2020, no further telemetered data will be available from the seafloor sensors.

Due to a bug in the mooring telemetry system, data during this time range was not telemetered to shore. It was recorded on the mooring and instruments and will be available in the recovered data streams.

CE09OSSM-MFD35-05-PCO2WB000

There is no pressure variable in the .nc files. This should be a coordinate.

By Lori Garzio, on 7/24/19

CE09OSSM-MFD35-05-PCO2WB000

There are no recovered_inst data available for download for any deployment. According to the ingest csvs, the recovered_inst raw data files are available for deployments 1-2, 4, 6-7 and missing for deployment 5. These files should be ingested or the datasets should be annotated to explain why the recovered_inst data aren't available.

Data are suspect for every deployment of this instrument because of the high percentage of values outside of global ranges. The dataset should be annotated if there is a known issue with this instrument to inform users if all or some data should be considered suspect.
