Test Notes

  1. no comparison: timestamps do not match
  2. missing: ['pressure']
  3. fail: data found in another stream (gaps: [3937, 4035] days: [3940, 4036])
  4. fail: check ['Nitrate Concentration - Temp and Sal Corrected', 'Dissolved Nitrate Concentration', 'Nitrate Concentration - Temp and Sal Corrected', 'Dissolved Nitrate Concentration']
  5. fail: data found in another stream (gaps: [51192] days: [51285])
  6. fail: check ['Dissolved Nitrate Concentration', 'Dissolved Nitrate Concentration']

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.

Data telemetry disabled due to chronic issues with power generation and management. The instruments could be revived to send data via telemetry when sufficient power is available. Note: Instruments may continue to collect data on internal battery power.

Deployment 11: UPDATED 2020-04-27: As of 2020-03-12 telemetered data for most instruments are being sent home via Iridium. A gap in telemetered data is expected between 2020-01-08 and 2020-03-12 and will not be backfilled but these data will be available upon recovery.* As of 2020-01-08 both fleet broadband telemetry pathways have failed and data can no longer be telemetered to shore from this mooring. Instruments will continue to log data which will be available upon recovery.

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

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.

Suspect data - salinity_corrected_nitrate and nitrate_concentration values jump at the end of the deployment.

highly variable nitrate_concentration values towards the end of the deployment, including negative values - possible biofouling?
