Objective	Haploops (tube-building amphipod crustaceans) populations are original and unique,but they are still poorly known and are most likely in a phase of expansion along coasts in Brittany. The general objective of this proposal is to understand the range of Haploops sp. communities, how they function and the role they play in the ecosystems holding them. This cruise was performed in the frame of the "Habitat" project.

Summary of measurements

-Benthic macrofauna samples taken with Van Veen grab.
-Benthic megafauna and fish sampled using modified (string) beam trawl.
-Sediment samples taken to characterize the type of sediment and the organic matter.
-Sediment cores (Reineck type corer) taken to sample the meiofauna (harpacticoid copepods and nematodes) and to characterize the sediment.
-Installation of benthic chambers designed to measure fluxes at the water-sediment interface (CALMAR chamber).
-Sampling of sources of organic matter (POM in sediment, POM in water column offshore and at coast) and consumers to analyze the isotope signatures.
