Objective

The main goal of this project is to characterize the sources of organic matter (terrestrial vs. marine) in the coastal zone. We will apply lipid biomarkers in combination with more conventional organic tracers. The innovative aspect of this project rests o n the application of a newly developed proxy for terrestrial organic matter characterization to a modern marine environment. For this purpose, the BIT (Branched and Isoprenoid Tetraether) index based on specific organic compounds will be applied to an extensive set of various continental and marine particulate matter and sediment samples from the river-dominated Gulf of Lions (NW Mediterranean).

The proposed combination of lipid biomarkers with bulk organic tracers represents a novel approach to discriminate the origin of organic matter in modern marine environments. Moreover, deeper knowledge on the basis of the BIT index and the validation of this proxy is needed to provide the paleoclimate community a simple and robust tool to reconstruct the terrestrial inputs into the marine environment and the hydrological variations on continents and hence to answer many currently unresolved questions about climate change. The results will also contribute to improve our knowledge of sedimentary processes, and sediment transport pathways from continent to deep-sea.

The impacts of storms and floods on the distribution and transfer of particulate organic matter in the coastal zones will also be assessed. Finally, broader impacts of this study to the scientific community include a better understanding of the carbon cycle in the coastal ocean and naturally occurring compounds and the processes that determine their fates. This increased knowledge will further serve to improve models for predicting the behaviour of anthropogenic contaminants in marine ecosystems.
