The NUTNR on the NSIF for CE04OSSM is starting to show signs of biofouling (beginning on approximately 2015-11-29). Nitrogen data (NITROPT) from this date forward for the CE04OSSM-00001 deployment should be looked at carefully and considered as suspect.

Data goes from ~50 umol/L to -200 umol/L in a matter of hours. Probably an instrument failure

Instrument not deployed during Fall 2016 cruise because its refurbishment was not complete before the cruise.

The Satlantic ISUS instrument has been discontinued, and all OOI ISUS units have been converted to the Sea-Bird SUNA model. A new data parser is in development, and any resulting data gaps will be filled once the parser has been delivered and the data are processed.

The datalogger computer crashed and had to be power cycled to restore operation. Telemetered data was lost for this time period.

Due to a bug in the mooring telemetry system, data during this time range was not telemetered to shore. It was recorded on the mooring and instruments and will be available in the recovered data streams.

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

Annotation ID 1410 should be updated when the parser is complete and the data from the new instruments is ingested.

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.
