|Objectives||The main aim of the cruise was to carry out a survey of Nephrops grounds in the Clyde, Sound of Jura and in Loch Torridon using underwater television and still camera equipment kindly loaned by the Institute of Geological Sciences, Edinburgh. The surveys in the Clyde and Sound of Jura were carried out in preparation for a programme of dives in Vickers' submersible PISCES which took place at the end of May in collaboration with the Ministry of Technology. Particular attention was paid to the conditions in these areas likely to affect the PISCES programme, such as bottom visibility and currents.
Specific aspects of the programme were:
1. Photographic and television surveys of the above areas to determine the density of Nephrops burrows. Studies of the diurnal activiity of Nephrops.
2. Studies of the distribution and abundance of larvae and juvenile Nephrops by plankton and grab sampling.
3. Tests of gravity corers, grabs, UMEL camera and "shark" transducer housing.
