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. Chl-a recorded by the glider was generally comparable to the CTD cast for D0003 and higher for the glider for D0006. Further analysis using the shipboard bottle data should be conducted. This is outside the scope of this project.

6-19% of the sci_flbbcd_chlor_units values for deployments 1-4 are outside of global ranges. Zooming in shows that most of those values are slightly negative.

Deployment: 1

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

By Lori Garzio, on 9/5/19

Deployment: 6

27% of seawater_scattering_coefficient and optical_backscatter values are NaNs for this deployment. Likely related to conductivity cell issue (annotation ID 940). Data after 11/12/2017 should be considered suspect.

The glider altimeter may have failed.

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.
