2015-06-11: Sue, Brad and Kat left Dingwall harbour on the the Bay Leader I to deploy DL in Aspy Bay (46 53.100' N, 60 22.320' W). This will be a two week mission to track tagged snow crab in Cabot Strait. Once DL in water, we used a test tag to verify VR2C functionality. All tests completely successfully and glider at full power.

2015-06-12: We will begin with a zigzag patrol. Each transect is 13km in length and spaced 1.4km apart. This allows some overlap assuming a detection range of 800m. This range can very depending on type of tag and water conditions.

2015-06-25: Sue, Brad and Kat recovered wave glider on the Bay Leader I in Aspy Bay for completion of 2015 Cabot Strait mission to track tagged snow crabs. Umbilical had one twist, small patch of paint scuffed off float and light housing had crack with obvious water damage to light. Returned to Dingwall harbour with no issues.
