Objectives and Narrative |
Reconstructing abrupt Changes in Chemistry and Circulation of the Equatorial Atlantic Ocean: Implications for global Climate and deep-water Habitats.
Objectives (a) Controls on coral habitats past and present Studying what controls the distribution of corals today and in the past requires systematic mapping, imaging and collections from deep-water coral habitats. Shipboard swath bathymetry was used for an overview of each feature, and to select sampling sites. Systematic dives up the slopes of each feature allowed collection of video, stills, live and fossil corals and seawater. In addition microbathymetry of unusual habitats was to gin a wider overview. Coral associates were imaged and collected to add depth to our knowledge of the coral habitats. (b) Development of geochemical proxies Core top sediments, live calcified corals and sponges were collected across a range of depths with associated seawater with sampling focused on the greatest possible range of environmental parameters (e.g. temperature, nutrient status, water mass). These samples will be used to test geochemical proxies. (c) Reconstruction of past climate Sediment cores and fossil corals were collected across the basin and at a range of depths to allow a history of the Atlantic to be reconstructed. (d) Ancillary Studies. A number of other collections were also made including plastics, rocks, sponges and genetics samples. |
