The overall objective of this proposal is to follow                     important biogeochemical pathways of organic matter recycling in-               situ by using carotenoids as tracer compounds.  Previous studies                have demonstrated that biological and chemical degradation  of                  carotenoids yield highly characteristic transformation products.                The distribution of these transformation products in deep-sea                   particulate matter as it sinks.                                                         These studies will focus on the relative abundances of                  carotenoid dehydrates (indicators of bacterial metabolism),                     carotenoid free alcohols (indicators of metabolisms by higher                   heterotrophs), and open epoxides (indicators of chemical                        degradation) in suspended particulate matter and sediment trap                  samples collected from the Black Sea and Eastern North Atlantic                 Ocean.  The differences in biogeochemical recycling processes of                these two areas, which result from the differences in water                     column chemistry, are expected to produce large but predictable                 differences in the distribution of carotenoid transformation                    products in particulate matter samples. //
