PurposeResearch
ObjectivesThe objectives of the cruise may only be broadly defined due to the multi-disciplinary and multi-institutional nature of the cruise. In general terms, the objectives were to undertake to a satisfactory extent the major proposed research activities of the individual research groups. A major core objective was to collect oxygen consumption and diffusion data using the new benthic Lander for the BENBO community as a whole at each of the three experimental sites. The first Leg of CD113 was devoted to oxygen micro-profile and gel work, and the second Leg devoted to chamber work. The mooring at site C only was to be turned around, and the bottom-mounted ADCP instrument at site B was to be recovered permanently. Throughout the cruise, satellite imagery of sea surface colour and temperature was obtained routinely to assess the nature and extent of the upper ocean phytoplankton bloom.
