Test Notes

  1. fail: data found in another stream (gaps: [1] days: [136])
  2. fail: check ['Nitrate Concentration - Temp and Sal Corrected']
  3. missing: ['pressure']
  4. fail: data found in another stream (gaps: [2] days: [2])
  5. fail: data found in another stream (gaps: [25, 8073] days: [25, 8073])
  6. fail: check ['Nitrate Concentration - Temp and Sal Corrected', 'Dissolved Nitrate Concentration', 'Nitrate Concentration - Temp and Sal Corrected', 'Dissolved Nitrate Concentration']
  7. no comparison: timestamps do not match
  8. fail: data found in another stream (gaps: [10743, 11158] days: [10751, 11158])

Fuel cell impacted available instrument power, so telemetered data are not available or reliable. Recovered data are available for instruments that could record internally.

UPDATED, 2019-03-25: The Satlantic ISUS instrument has been discontinued, and all OOI ISUS units have been converted to the Sea-Bird SUNA model as of the start date/time of this annotation.

CP04OSSM D00009 buoy broke free and went adrift on 1/30/2019, 1500UTC. All instruments on the MFN ceased telemetry on 1/30/2019 and instruments on the buoy/NSIF continued to sample through 2/1/2019. No more telemetered data expected for this deployment.

Deployment 11: Delivery of telemetered data from instruments on DCL26 could potentially be delayed up to 24 hours.

Missing data should be annotated.

By Lori Garzio, on 7/23/19

CP04OSSM-RID26-07-NUTNRB000

Data generally look suspect for all deployments of this instrument (the ISUS model) because of the prevalence of negative values. 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.

CP04OSSM-RID26-07-NUTNRB000

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

Deployment: 1

recovered_inst data aren't available for download for this deployment. According to the ingest csv, the raw data files aren't available due to possible instrument failure. This should be annotated in the system.

Suspect data - 100% of the values for salinity_corrected_nitrate are outside of global ranges (50-70 umol L-1).

recovered_inst data aren't available for download for this deployment. The dataset should be annotated to explain why.

Deployment: 3

There are a lot of unreasonable values and outliers throughout this deployment.

Suspect data - 100% and 69% of the values for salinity_corrected_nitrate and nitrate_concentration are outside of global ranges. Possible biofouling towards the end of the deployment.
