PurposeResearch
ObjectivesSecond leg of a 2-leg cruise with the following objectives:
(1) To conduct sound ranging trials in the eastern Atlantic from 30-45 N to assess feasibility of long-range detection of neutrally-buoyant floats.
(2) Investigate abyssal water exchange between Madeira and Iberian basins by studying flow through the 'Discovery Gap'.
The work undertaken on this leg was:
(1) Servicing the sound source mooring deployed on leg 1 and its retrieval at the end of the sound ranging experiment.
(2)Working a series of hydrophone and CTD profiles at varying distance from the sound source mooring.
(3) Release and tracking of neutrally buoyant floats in the Discovery Gap.
(4) CTD survey in the Discovery Gap, including yo-yo time series.
