Purpose | Trials |
Objectives | This was a joint cruise between the Department of Earth Sciences, University of Cambridge, and the Institute of Oceanographic Sciences. The objective of the Cambridge party was to carry out trials of a new electromagnetic deep tow sounding system; that of the IOS was to test new instrumentation including midwater particle sampling equipment, a deep sea precision echo sounder and FSK telemetry system. The opportunity was also taken by IOS to carry out seismic explosive trials and to recover and relay a bathysnap instrument. If time allowed it was also hoped to attempt the recovery of certain equipment in the Porcupine Sea Bight area. Unfortunately the cruise had to be shortened by one day leaving very little time for salvage activities. |
