Abstract:
The supply of food to the ocean floor and benthic community responses to variations in the downward flux of organic matter (OM) over space and time are fundamental issues of biological oceanography. Changes in surface water productivity may be important drivers for variation in the biodiversity of deep-sea sediments; biogeochemical provinces evident in surface waters are mirrored in benthic community structure. However, the relationship is not simple: recent dramatic changes in species dominance in the abyssal North Atlantic are related to a change in the flux of OM to the seafloor. So understanding patterns of biodiversity in the deep sea and their link to surface water productivity remains a major challenge. We propose to tackle the issue by focussing our studies on two contrasting areas of surface productivity around the Crozet Plateau (Southern Indian Ocean). We will adopt an integrated, multidisciplinary approach which will involve assessment the OM input to the deep-sea floor (export production), the ambient biogeochemistry of the sediment surface, the benthic community structure and diversity (molecular and morphological approaches), the activity of fish and the sediment community (seabed lander experimentation), the uptake of specific biochemicals by key species and their influence on reproductive processes.
