Test Notes

  1. fail: data found in another stream (gaps: [7209, 7239] days: [7211, 7241])
  2. fail: check ['Nitrate Concentration - Temp and Sal Corrected', 'Dissolved Nitrate Concentration', 'Nitrate Concentration - Temp and Sal Corrected', 'Dissolved Nitrate Concentration']
  3. missing: ['pressure']
  4. no comparison: timestamps do not match

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.

Deployment 3: Telemetered files started to contain bad characters around 6/8/2017, and most data were bad as of 6/19/2017. Upon recovery, instrument bulkheads were heavily corroded and bent.

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 - 97% of the values for nitrate_concentration are outside of global ranges (mostly negative).
