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 D0001, D0003, D0005, D0007, and D0008. Chl-a recorded by the glider was higher compared to the CTD cast (particularly at the chl-a maximum). Further analysis using the shipboard bottle data should be conducted. This is outside the scope of this project.

The data at the end of the deployment (when the glider was drifting/stuck at the surface?) should be annotated as suspect.

85% of the chl-a data are negative. This should be annotated until the issue is resolved.

The sampling pattern for all instruments changed on 11/15/2015. This should be annotated.

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

By Lori Garzio, on 5/7/19

99% of the chl-a data are negative. This should be annotated until the issue is resolved.

Suspect data >400 dbar in the beginning half of the deployment.

By Lori Garzio, on 5/8/19

47% of the chl-a data are negative. This should be annotated until the issue is resolved.

By Lori Garzio, on 5/8/19

Suspect data >800 dbar at the end of the deployment.

By Lori Garzio, on 5/8/19

Lots of noise in the data through the water column, particularly between 11/8/2017 - 11/20/2017
