WaQMoS : Coastal waters quality surveillance using bivalve mollusk-based sensors


WaQMoS : Coastal waters quality surveillance using bivalve mollusk-based sensors

Project funded by the ANR

2015 – 2020


The main goal of the project is to develop a biosensor, based on measurements and interpretation of bivalves mollusks behavior, for remote online detection of coastal water pollution and climate change consequences.

The biosensor development will be based on EA team’s (CNRS UMR 5805 EPOC, Arcachon) technology of high-frequency noninvasive valvometry for mollusks and by applying the systems and control theory methods of VALSE team (Inria, Lille). The monitoring system should have intelligent capabilities and possess long term autonomous work without human intervention.

This is an interdisciplinary collaborative project (marine biology – electronics – applied mathematics). One of the main potential applications of the monitoring technique is water quality surveillance along coastlines and ports (harmful algal bloom events, noise pollution), and around oil or wind energy production offshore platforms. Another one is monitoring changing ecosystem due to global warming in sensitive areas such as the Arctic zone.

People involved in the project

VALSE team, Inria Lille – Nord Europe:

The VALSE team is developing an estimation theory, built around differential algebra and operational calculation on the one hand, and high gain algorithms (sliding mode, homogeneous, etc.) on the other hand.

Denis Efimov (project leader), CR Inria, is a recognised expert in automatic control theory. His main research interests include nonlinear oscillation analysis, observation and control, nonlinear system stability. Rosane Ushirobira, CR Inria, is working on algebraic methods for signal and parameter estimation, based on differential algebra and Weyl algebra. Hafiz Ahmed, PhD student, was hired by Inria/Hauts-de-France Region and defended his thesis in September 2016. Nelson de Figueiredo Barroso, PhD student, is hired by WaQMoS/Hauts-de-France Region for three years from December 1st, 2017.

EA team of EPOC laboratory: 

The EA team of EPOC laboratory is specialized in eco-physiology and chronobiology of bivalve mollusks as well as respiratory physiology and ecotoxicology of aquatic animals. Since 1997, EPOC is developing High Frequency Non-Invasive (HFNI) valvome- try, a unique technique, currently available at international level, to analyze the movement of valves in mollusks, i.e. their behavior.

Jean-Charles Massabuau, DR CNRS émérite is a world class researcher working in bio-monitoring with bivalves at sea using unmanned systems, and impact of contamination to sub-lethal doses and global warming.Damien Tran, CR CNRS, specializes in bio-monitoring with bivalves at sea using unmanned systems, chronobiology and behavioral changes and biological rhythms of oysters.Pierre Ciret, IR CNRS, works in the field of electronics applied to biology. Mohamedou Sow, Research Engineer ADERA, is in charge of development, adaptation and integration to the operational chain of codes used in the MolluSCAN eye data production system. Bruno Etcheverria, TCE, is an experimentation assistant. Mickael Perrigault, Research Engineer, was hired by WaQMoS in January 2016 for two years. Laura Payton, Research Engineer, was hired by WaQMoS in October 2017 for ten months.
