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 3 consecutive down and up casts for CE05MOAS-GL312-04-DOSTAM000 on 7/8/2014 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 2 was a test deployment - no data available.

The deployment 3 .nc files for every instrument are missing coordinates lat, lon, and pressure.

sci_abs_oxygen (µmol kg-1) is an array of all NaNs for deployment 3. According to the provenance.json file:

{
"derived_name": "sci_abs_oxygen",
"missing": [

One suspect profile near the end of the deployment.

A substantial amount of data are outside of global ranges in the surface layer (<25 dbar). This is most evident in sci_oxy4_saturation (attached plot shows only data within global ranges). This should be investigated.

By Lori Garzio, on 4/25/19

Glider was out of the water (see annotation ID 888 - fisherman picked it up) - any data available during this time range should be flagged as "bad".

By Lori Garzio, on 4/25/19

It looks like the glider started drifting on/around 5/20/2018. Data should be annotated.
