Deployment: 2

Suspect upward_velocity values for deployments 2 (top panel in attached plot) - values often exceed northward and eastward values.

Deployment: 3

There are no recovered_inst data available for download for deployment 3. According to the ingest csv, recovered_inst raw data files are available but there were parsing issues. This should be investigated.

Deployment 1: Buoy log files showed that seawater was first detected inside the buoy well on 3/26/2015. Both leak detectors showed increasing presence of water over the period of deployment. Upon recovery of the mooring, no external damage was visible and the buoy did not appear to be floating lower than normal.

According to the manufacturer, data are suspect when the instrument is tilted more than 20 degrees (measured by pitch and roll).

Deployment 3: Upon recovery, the instrument clock was offset by approximately 2 months (on 01-16-2018T17:39:19Z the instrument clock read 11-19-2017T04:11:57Z).
