StatusCompleted
Port of departureGibraltar, Gibraltar
Port of returnFunchal, Portugal
ObjectivesThe objectives of this cruise were to:
(1) To recover moorings set in the Discovery Gap in July 1982.
(2) To carry out CTD and bathymetry surveys in the Discovery gap area.
(3) To deploy three autonomous listening stations and undertake a CTD survey in the vicinity of the moorings.
(4) To deploy and track neutrally-buoyant SOFAR floats.
(5) To deploy a moored current meter array west of Madeira.
(6) To occupy CTD stations within the Madeira current meter array.
All objectives were accomplished.
