Objective | The Isobaie2 cruise incorporates the scientific objectives of the Isobent and Moresca projects: studying the original telluric signal on coastal food webs based on the use of stable carbon and nitrogen isotope in primary consumers (filtering molluscs) and secondary consumers (invertebrate and fish predators) both benthic and demersal along a dual gradient shore-offshore/ bathymetry. Bay of Vilaine / Mor Bras and Bay of Brest / Iroise Sea are the two zones studied in these projects. More specifically, the Isobaie2 cruise aimed to collect seston, sediment, macrobenthos and fish samples at 14 stations on an estuary / continental slope gradient. The related projects are EC2CO, PNEC Isobent, on continental signal and benthic contribution traced using isotope signatures of benthic invertebrates and UEB EPT Moresca on organic matter and benthic food webs in a coastal ecosystem under anthropogenic influence. |
