BenthOBS is the French national network for the observation of marine benthic macrofauna (macrozoobenthos) deployed on the French coasts in metropolitan and ultra-marine areas. It is part of the France’s multi-agency infrastructure for coastal ocean observations (IR-ILICO) and is managed by the Oceanology and Geosciences laboratory in Wimereux. It brings together laboratories from the three mainland and overseas (La Réunion Island) seaboards, under the supervision of the universities, the CNRS, Ifremer and the Muséum National d'Histoire Naturelle.

Sampling, analysis and taxonomic identification follow a common standardised protocol. In addition, the operators participate each year in a benthic taxonomy inter-comparison workshop.
