Arcachon Bay, France

14 May 2017

Demonstration Day

Goal and Scope

On two different days during the SCHeMA-V field campaign that took place onboard the R/V Planula IV (INSU) from May 14th to 19th, stakeholders and potential end-users were invited on-board to give them the opportunity to see the SCHeMA sensing probes operating in real conditions. The participants included representatives of the SOARC (Service d'Observation du Bassin d’Arcachon that is part of the French National Observatory Service for Coastal Environments: SOMLIT); the enterprise Geo-transfert (ADERA, transfer of technology; hosted at Bordeaux University); the Agence de l'Eau Adour Garonne (French National Water Agency).

The Arcachon Bay is one of Europe’s most important oyster production zones. However, the Arcachon Bay has been facing constantly growing pollution of its waters in the past decades (in particular Cu and As contamination of seafood, as well as abnormal proliferation of green algae). Shellfish are episodically banned from consumption by the prefecture. The oyster farmers, challenging the reliability of tests currently performed, await the implementation of a new generation of tests, providing more representative and reliable information on environmental quality than the traditional ones

The SCHeMA integrated mapping system - with it capability to i) simultaneously monitor in situ and in real-time the bioavailable trace metal species, nutrients, various algal groups including toxin producing cyanobacteria and dinoflagellates, and bio-physico-chemical master variables; and ii) its real-time open access to the data - could be a valuable tool for both continuous control of the water quality of the Bay and the development of warning system.
