Objective

Geochemical characterization of fluid seeps in the Bay of Biscay: samples taken in situ with ROV Victor on fluid seep sites on the Aquitaine shelf for analysis of fluids, sediments, rocks (authigenic precipitates including carbonates), fauna and microbial assemblages. This falls under the PAMELA project.
