Deployment 1: Glider suffered progressive steering failure and went adrift in May 2016. Digifin was inoperable at the time of recovery, small chips on wings, moderate biofouling.

Deployment 2: Conductivity measurements are out of range and suspect from 2019-11-21 through 2019-11-27. We believe that the CTD was fouled during this period but cannot know for sure.

Deployment 2: This glider is being flown to the Oregon coast due to the possibility of limited recovery options at the Papa Array this summer. The glider left the array on 2020-04-23 and the science sensors will continue sampling as it flies toward the coast.

GP05MOAS

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

23% of deployment 1 sci_seawater_density values are NaNs, and some data missing from recovered_host stream are found in the telemetered stream (Redmine 14654)
