Note
Data generally look suspect for both deployments because of the high percentage of values that are nans, fill values, and outside of global ranges - did not calculate final data ranges.

* UPDATED, 2019-01-25: 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. The pco2_pco2wat algorithm is under review and can be viewed at https://github.com/ooici/ion-functions/blob/master/ion_functions/data/co2_functions.py.

Deployment 1: Recovered_instrument data not available - unable to communicate with the instrument after recovery.

Deployment 1: Buoy log files showed that seawater was first detected inside the buoy well on 3/26/2015. Both leak detectors showed increasing presence of water over the period of deployment. Upon recovery of the mooring, no external damage was visible and the buoy did not appear to be floating lower than normal.

There are no recovered_inst data available for download for deployments 2-3. According to the ingest csvs, the recovered_inst raw data files are available for these deployments. These files should be ingested or the datasets should be annotated to explain why the recovered_inst data aren't available.

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

Data generally look suspect for both deployments of this instrument because of the high percentage of values that are nans, fill values, or 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.

Deployment 2: The recovered_host data from the following instruments have the same 4 data gaps [['2015-12-04', '2015-12-14'], ['2016-01-06', '2016-01-11'], ['2016-02-05', '2016-02-10'], ['2016-03-11', '2016-03-14']]. These gaps should be annotated to explain why the data are missing, or gaps should be filled in if the data are available. [02-FLORDG031, 02-FLORDG032, 02-FLORDG033, 02-DOSTAD031, 02-DOSTAD032, 02-DOSTAD033]

Deployment: 1

There are no data available for download for this deployment. Recovered_inst data aren't expected (see annotation ID 615), however according to the ingest csv, recovered_host raw data files are available. These files should be ingested or annotation ID 615 should be updated to explain why no data are available.

Deployment: 2

There are only 65 data points for this deployment, and 50 of those are fill values for pco2_seawater.

Suspect data - 95% of the values for pco2_seawater are nans, fill values or outside of global ranges.
