    2014-10-21: Adam, Sue, Brad, Cailin and Duc headed out on DiveCom to deploy wave glider. Mission objective to offload VR4s in OTN Sable Island Array and Halifax Line. Deployed at 44 32.00 N, 63 25.00 W. During launch, tag line became loosely wrapped around rudder area, lifted back up to remove line. Once in water, issues with comms - commands not being acknowledged. Recovered glider, performed a hard reboot of the float. After reboot, comms re-established, LRI gave OK to re-launch.

    2014-11-01: Primary GPS malfunctioning, requiring float to be rebooted to fix. Secondary GPS (weather station) also malfunctioning intermittently (LRI has seen issues with these units). Will leave weather station on (end duty cycling) in case primary GPS fails.

    2014-11-03: DL still heading in reverse direction. This is likely a combination of waves, strong currents, and line following being turned on.

    2014-11-22: Have had issues connecting to some stations. Seems to connect better with lowered baud rate (300 bps) and power levels (-6 or -12 dB). Will update some of the station default parameters.
