Deployment 7: Glider's altimeter failed on 5/27/2019 so it will be limited to sampling the bottom line of the FZ box and to 500m until the end of the deployment.

CP05MOAS

Bad altimeter pings are apparent in many deployments of the coastal gliders. A few example plots are attached - m_water_depth plotted as semi-transparent bathymetry.

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.

Comparisons with the shipboard CTD casts were done for D0003 and D0006. Glider conductivity and salinity are unreasonable for the D0006 comparison. Further analysis using the shipboard bottle data should be conducted. This is outside the scope of this project.

Glider doesn't look like it sampled according to plan. This should be annotated.

CP05MOAS-GL387-03-CTDGVM000
Deployment: 6

30% of conductivity, salinity, and 40% of density values are nans or outside of global ranges. Annotation ID 940: conductivity sensor intermittently failed. It looks like it started to fail on/around 11/12/2017
