BIOSYS The second of three BIOSYS cruises lead us to relatively shallow ecosystems of deep water corals at the Mingulay reef area off the coast of Scotland (Fig. 1). In 2005, the first cruise, a joint BIOSYS/HERMES cruise led us to coral reefs of the Rockall Bank/Trough area in the NE Atlantic with coral banks ranging in depth from 500 to 800 m. During the BIOSYS cruise 2006 one intention was to compare the relatively deep corals to corals from the much shallower depth near Mingulay, where deep water coral bioherms are found in water depths as shallow as 100 m. The most abundant stony coral, Lophelia pertusa, was studied and experiments with living corals directly on board the research vessel were carried out in temperature-controlled cool-containers at 10C to study microbial abundance, and microbial community stucture associated with the corals and within the gastral cavity of these corals. Further, radioisotope labeling experiments (3HLeucine, 14C-sodium bicarbonate and 45CaCl2) were used to study microbial proteinsynthesis, microbial autotrophy and coral calcification. Live coral sampling and maintenance at the NIOZ climate chambers for subsequent experiments is another task of the cruise. In begin 2006, part of the live Lophelia pertusa and Madrepora oculata kept at a NIOZ climate chamber (sampled during BIOSYS/HERMES cruise in 2005) have been transported to the Oceanium at Rotterdam Zoo where they are maintained for observation. With the option to later set-up a cold water coral bioherm show-aquarium at Rotterdam Zoo the BIOSYS 2006 cruise was joined by the curator of the Oceanium. |
