Dissolved oxygen noise increased, possibly from biofouling. (annotation ID 769)

Temperature and salinity corrected dissolved oxygen (umol kg-1) ends on 1-4-2017 because the collocated CTD data are not available after this time period (the CTD was damaged).

The deployment 3 netCDF file contains the variable int_ctd_pressure and that variable contains valid pressure data, however it does not have any attributes (e.g. standard_name, units) and this variable is not listed as a coordinate for any of the variables in the file. There is pressure data from the collocated CTD (GA01SUMO-RID16-03-CTDBPF000) for the beginning of deployment 3, and these CTD files are included in the thredds server when I downloaded the DOSTA data (https://opendap.oceanobservatories.org/thredds/catalog/ooi/lgarzio@marine.rutgers.edu/20190111T235754-GA01SUMO-RID16-06-DOSTAD000-recovered_host-dosta_abcdjm_dcl_instrument_recovered/catalog.html). int_ctd_pressure is a coordinate in the deployment 1 and 2 files. It should also be a coordinate for deployment 3.

Oxygen concentration and saturation drop off - data are suspect and should be annotated.

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.
