Report describing the methodology and results of the simulations

The objective of the ANODE project was to quantify the chemical compounds emitted by the galvanic anodes of ORE structures and the risk associated with their dispersion in the marine environment. By combining ecotoxicological expertise and hydrodynamic modelling, the ANODE project has determined that there is no risk associated with most of the elements making up galvanic anodes, namely zinc, iron, copper and cadmium. On the other hand, concerning aluminium, additional experiments are necessary to conclude. The two currently available Predicted No-Effect Concentrations (PNECs) do not seem suitable for this assessment. These thresholds must therefore be refined and include data from in situ measurements in order to be able to estimate the possible risk associated with aluminium releases.

This paper presents the assessment of potential impacts of changes in species distribution by climate change on the extended Seine Bay ecosystem.

This study investigated the effects of a spatial closure during the exploitation phase of an offshore wind farm in the extended Bay of Seine (English Channel, France) using Ecospace, a spatially and temporally explicit module of Ecopath with Ecosim.

The objective of the CARAVELE project was to improve the characterisation of extreme winds by combining atmospheric models with satellite and in-situ observations.

The objective of the TROPHIK project was to model the role of offshore wind turbines and other anthropogenic activities in modifying the functioning of thefood webs of the Bay of Seine by taking climate change into account. TROPHIK has initiated a methodology to move from the sectoral vision of environmental impact studies to a functional and holistic approach. The analysis of the sensitivity of the functioning of the food web to the development of offshore wind farms represents a solid basis for recommending new areas of implantation. This approach will be completed within the framework of APPEAL and WINDSERV by integrating the societal and economic environment as well as biogeochemical forcings

This document briefly presents the methodology used to build the Ecosim and Ecospace models representing the extended Seine Bay ecosystem as well as the main results.

The objective of the COME3T project were: • To provide elements of expertise, synthesis and recommendations on the identification of environmental priority issues for the ORE through the establishment of a lead neutral experts committee. • To install a French and unique network of experts that can be consulted by all ORE stakeholders.

This document identifies gaps in knowledge and emphasizes the need for long-term monitoring of marine mammals in order to better understand the impacts of wind turbines on them
