Cruise Inventory Information
| Long name | RRS Discovery (74E3) cruise D130A |
|---|---|
| Short name | D130A |
| Objectives and Narrative |
First 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) Bathymetric survey of the Discovery Gap (2) Recovery of two moorings deployed in 1981 in the Discovery Gap. One recovered, but the other refused to surface. (3) Working CTD stations in the Discovery Gap (4) Deployment of a sound source mooring on the Azores-Gibraltar Ridge (5) Working a series of hydrophone and CTD profiles at varying distance from the sound source mooring. |
