PurposeResearch
ObjectivesThe aims were to lay the three 'E' current meter moorings forming the central triangle of the C-Scale array and to make trials with the Batfish system to get it into a fully operational state and to gain experience in using it. The principal objectives of the biological programme were to collect material for an investigation into the possible existence of biochemical cycles associated with the diurnal migrations of pelagic decapods, to collect samples of micro-nekton and zooplankton from depths between 200m and 5000m and to obtain live material for physiological work
