Glider optodes typically exhibit a sensor lag of 20-25 seconds. Example attached of several segments with consecutive down and up casts for CP05MOAS-GL335-04-DOSTAM000 on 10/26/2015 showing a typical measurement time lag. Profiles should be analyzed for individual time lags and data should be adjusted. OOI doesn't necessarily need to make the adjustment but users should be aware of the issue.

Comparison with the shipboard CTD cast was done for D0001. Salinity from the glider was lower at the surface and higher than salinity from the CTD cast between 100-200 dbar. Further analysis using the shipboard bottle data should be conducted, which is outside the scope of this project.

95% of sci_seawater_density values are NaNs. Lat and lon are parameters used in the data product algorithm, so I think this got messed up with the re-organization of the glider lat/lon parameters. See Redmine ticket #14486

Deployment 1: Deployed on 12/20/2015, recovered on 12/25/2015 20:40 UTC for ballast correction and was re-deployed. Starting around 5/1/2016, glider became increasingly difficult to steer. Glider stopped profiling on 11/6/2016 to conserve remaining battery power. At recovery, barnacles were present mostly on the underside of the glider, and were not in an area to hinder flight performance.
