Following a system outage, the optode port agent failed to restart. It was manually restarted on 2019-11-15 at 18:34:11.599. The missing oxygen data will be played back into the system, but can also be found in the CE02SHBP-LJ01D-06-CTDBPN106 data stream.

Review Notes

Metadata Start Date End Date Comment

There are no data available for download for deployments 1-4 because the data were delivered via the CTD data stream (Redmine 8662). Now that the DO instrument has been separated from the CTD, the old DO data should be ingested in the DO data stream. Users currently have to go to the collocated CTD reference designator to get the DO data prior to 2018-11-07.
