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

Missing data for deployments 1-5 should be annotated.

Annotation ID 1409 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.

NUTNR has been showing light values equivalent to dark values (i.e. all zeros) since 2 August.

Communications with instruments on the NSIF for CE02SHSM are offline. Monitoring current draws to the NSIF shows a pattern of increased and expected current draws every 15 minutes, corresponding to the instrument sampling schedules. This suggests that the DCLs and attached instruments are still operating, but communications to the system are offline, reason unknown. Affected systems are: CPM2, DCL26: ADCPT, VELPT, PHSEN, uCSPP (acoustic modem communications), NUTNR, SPKIR, DCL27: OPTAA, FLORT, DOSTA, CTDBP. NSIF communicated starting again early on the 14th. Logs from NSIF systems indicate that the systems and instruments are still working, pointing to a communications issue between the NSIF and the surface buoy telemetry system.

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.

Due to reduced power on the mooring (limited recharging of the batteries with light winds and sea lions blocking the solar panels), we have had to reduce the operating schedule of the 7 meter platform. Normally we run the system continuously, but have reduced that schedule to hourly.

Due to an intermittent communications issue with DCL26, we are not receiving data from the instruments consistently. We expect the data to be available upon mooring recovery.

During a large storm event on 2020-01-11, power from the wind turbines was lost. This is the primary means of recharging the battery system on the mooring. With the loss of recharging power, we have had to implement a conservative power model. These systems and instruments have been disabled for the foreseeable future, and no further data will collected from them.
