Deployment 2: No telemetered or recovered_host data expected.

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

Deployment 4: The PRESF instrument deployed was a Series B which has s 300 psia Digiquartz strain gauge rather than the Series C which has a 1000 psia Digiquartz straingauge. The PRESF-B was deployed outside of operational range; pressure values are incorrect.

No telemetered data are expected because of ground faults on the seafloor Multi-Function Node. Recovered data are available from instruments recording internally.

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: MFN offline due to high voltage short on 2019-11-15. No telemetered data expected from instruments on the MFN; instruments with external batteries will continue to log internally.

For deployment 1, the deployment depth in asset management is 455, but the pressure in the files is 472. For the rest of the deployments, the difference between the AM depth and pressure in the files is 7-18.

It is unclear what the second dimension for the wave_burst seafloor pressure is. Right now it's an index from 0-1023. This dimension should be described in the documentation and/or global attributes.

presf_tide_pressure and presf_wave_burst_pressure are all fill values for deployment 2. According to the provenance.json computed_provenance errors, the calibration values are missing.

presf_tide_pressure values are around 183 dbar when the instrument was deployed at 446 according to asset management. Excluding from final data ranges. presf_wave_burst_pressure values are more reasonable around 459 dbar.
