Abstract/Summary

This cruise was carried out on behalf of BP Angola and comprised a seabed environmental survey of Angola Blocks 18 and 31 (bathyal SE Atlantic). Seabed sampling was undertaken by Megacorer to provide samples for macrobenthos, hydrocarbon, heavy metal and particle size analysis. Seabed photography (still and video) was undertaken with the NOC WASP vehicle. Baited, time-lapse camera deployments were undertaken using the BP ROBIO system (Oceanlab, Aberdeen). The survey spanned water depths of 1300-2050m over the Angolan Margin and included studies in and around seabed pockmarks and salt diapirs. Some indications of fluid flow and chemosynthetic communities were encountered.
