French Zostera Marina and Zostera Noltei abundance data are collected during REBENT monitoring surveys on the English Channel / Bay of Biscay coasts. Protocols are implemented in the Water Framework Directive.

This dataset gathers isotopic ratios (carbon and nitrogen) and concentrations of both priority (mercury species and polychlorinated biphenyls congeners) and emerging (musks and sunscreens) micropollutants measured in a host-parasite couple (hake Merluccius merluccius muscle and in its parasite Anisakis sp) from the south of Bay of Biscay in 2018.
