PurposeResearch
ObjectivesThe aim of the project is to deploy autonomous vehicles in the North Sea in order to demonstrate long term monitoring capability of ocean health.

Cruise objectives were to,
1. Deploy 2 Slocum submarine gliders: 305 (Dolomite) and 331 (Coprolite).
2. Recover 2 Slocum submarine gliders: 444 (OMG-Kelvin) and 438 (Frazil).
3. Collect CTD profiles and discrete water samples for calibration of glider sensors following deployment and prior to recovery.

Unit 444 for recovery is a specialist glider and is longer and heavier than the standard Slocum glider; ~80kg in air and 2.1m long. This additional bulk is to accommodate an integrated ADCP and externally mounted microstructure package.
