ABSTRACT
Transmission cables from offshore wind farms in coastal areas are expected to grow rapidly in the coming years and increase potential environmental impacts. Very little research has been conducted on the role of increased turbidity, noise and electro-magnetic fields linked to the installation of transmission cables on the seabed. Our project called OASICE evaluates the disturbances linked to turbidity and noise produced during and after seabed installations with a natural sensor : Pecten maximus, the great scallop. This organism naturally present in shallow coastal marine areas is a potential indicator of ecosystem perturbations linked to installation of transmission cables.

OASICE is the result of a cooperation between RTE and TBM environment with Sylvain Chauvaud (TBM environnement), Pierre Chauvaud (TBM environnement) Laurent Chauvaud (LEMAR, Université de Bretagne Occidentale) Julien Thébault (LEMAR, Université de Bretagne Occidentale) and Damien Saffroy (RTE).
