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.

Comparison with the shipboard CTD cast was done for D0001. The shipboard CTD cast data are corrected for temperature, salinity, and depth (Redmine 14230). The L2 DO data product (corrected for temperature, salinity and depth) is lower for the glider compared to the shipboard data. This could be related to the issue of incorrect default salinity settings on some glider optodes (Redmine 13575). Comparison to the shipboard bottle data is outside the scope of this project. Note: the conversion from ml/l to umol/kg for the shipboard DO = DO (ml/l) * 44.661 / 1.025.

Deployment 1: Glider went adrift and stopped collecting science data on 9/9/2016. It was recovered covered in barnacles and missing its right wing.
