Objectives1. To lay and recover 6 moored current meter stations in a line stretching from Land's End to Ushant.
2. To complete a temperature-salinity and echo-trace survey over the region between the Mid-channel and 7 degrees W.
3. To track the drift of parachute drogues within short-term triangles of moored current meter stations built up from the established line of moored stations.
4. To test:
a. the MAFF acoustic release system at a depth of about 600 m and if the test is successful to leave 4 releases out in the field to be recovered by CIROLANA 1/74. (The single line deep mooring in this case to be laid via the free-fall technique from the stern deck).
