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.

Deployment: 1

100% of deployment 1 sci_seawater_density values are NaNs (because lat and lon are missing)

Based on the data, this glider looks like it had operational issues during the second half of the deployment 1. This should be annotated.

GP05MOAS-GL365-04-CTDGVM000
Deployment: 2

50% of deployment 2 sci_seawater_density values are NaNs, and some data missing from recovered_host stream are found in the telemetered stream (Redmine 14654)

Deployment 2: Glider recovered by a ship of opportunity (R/V Sikuliaq) due to limited battery power. Science sensors were turned off on 1/27/2017 to conserve battery, then resumed sampling around 4/2/2017 to 5/1/2017.
