Objective | The Isobaie cruise focused on the Isobent project's scientific objectives, i.e., to study the terrigenous signal in coastal food webs by using stable carbon and nitrogen isotopes in filter-feeding mollusks and the relative contributions of benthic and primary production in these animals along a bathymetric gradient. The project's two study zones are the Bay of Vilaine / Mor Bras and the Bay of Brest / Iroise Sea. The Isobaie cruise's more specific objective is to collect samples of the seston, sediment and macrobenthos, especially filtering mollusks along a gradient from the estuary to offshore at a dozen stations. This falls under the EC2NO and PNEC Isobent projects: Continental signal and benthic contribution tracked using isotope signatures in benthic invertebrates. |
