Deployment 1: Glider was damaged in Jan. 2016, likely during a period of bad weather. It was able to dive and collect data, but not maintain position. Last science data received on 3/16/2016. Glider was recovered in the Davis Strait.

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. The available science parameter values and patterns are comparable between the glider and CTD cast (although there was a much wider range of salinity values from the glider at the surface). Further analysis using the shipboard bottle data should be conducted. This is outside the scope of this project.

98% 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
