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.

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.
