ObjectivesTo obtain a suite of benthic samples from the Porcupine Abyssal Plain (48 50'N 16 30'W) as part of the IOSDL 'DEEPSEAS' programme and wider CEC MAST II funded project for comparison with previous cruises to this site (RRS Discovery 185, RRS Challenger 79) and other NE Atlantic sites (Madeira Abyssal Plain, RRS Discovery 194; Cape Verde Abyssal Plain, RRS Discovery 204).
To recover a Bathysnap (time-lapse camera and current meter) from the main study site, originally deployed from RRS Charles Darwin in September 1992. Time permitting, to visit a site on the Goban Spur to follow up photosledge transect carried out during RRS Challenger 94, which revealed abundant populations of the xenophyophore Syringammina sp..
