Monitoring of fishing activities

The fishing activity in the Bay of Saint-Brieuc represents an important part of the local economy. The objective of the monitoring of the fishing activities is to evaluate...
map-photomontages-2

Photomontage after construction

The objective of this measure is to validate that the photomontages presented in the framework of the impact study were representative of reality once the park...
chiropterans

Monitoring of chiropterans in the exploitation phase

During the operation phase, 8 wind turbines will be equipped with acoustic recording stations (ultrasound) in order to evaluate and characterize the activity of the...
chiropterans

Monitoring of chiropterans in the construction phase

The methodology consists in equipping a ship and the Grand Léjon lighthouse with an acoustic system including an acoustic recorder, a microphone...
ailes-marines-dry eggs

Monitoring of the fisheries resource

The objective of this monitoring is to evaluate the impacts of the construction and operation of the offshore wind farm and its connection on the fisheries resource...
dapuhin-risso

Passive acoustic monitoring of marine mammals

The objective of the "passive acoustic" monitoring of marine mammals is to provide information on the activity of cetaceans in the area of the offshore wind farm before construction (state of...
ailes-marines-goelands-adult-silver

Monitoring of breeding colonies

The objective of the measure is to improve the knowledge on the breeding colonies of the bay of Saint-Brieuc. This follow-up does not have for objective to replace the...
ailes-marines-goeland-juvenile-silver-in-flight

Visual monitoring of marine mammals and birds

The main objective of the "visual" monitoring of marine mammals and birds is to determine the impact of the works and the operation of the wind farm off the coast of...
carte-ile-tome

Benthos / water / sediment monitoring

The operations are part of a global project of ecological restoration of the island in the profile of the colonies of marine birds nesting. Indeed, the...
ailes-marines-chicks-d-alcids

Telemetric monitoring of Alcids

The measure concerns the Torda Penguins and the Common Murres breeding in the colony of Cap Fréhel. It is a question of specifying the ecology of these two species and of...
fou-de-bassan

Telemetric monitoring of Northern Gannets

The objective of the measure is to improve the knowledge on the ecology of the Northern Gannet in Saint-Brieuc Bay. This monitoring is not intended to replace the existing monitoring of the...
ailes-marines-goeland-adult-silver-flying

Monitoring of Avifauna by marine radar

The monitoring of avifauna by marine radar will be carried out using an automated radar/camera system installed in the park. The vertical data will provide...
goeland

Monitoring of Avifauna by ground radar

As the offshore radar can only be functional when the wind turbines are powered up, a land-based radar monitoring system is in place before and during construction....
ailes-marines-chicks-d-alcids

Monitoring the dispersion of Alcidae chicks

The objective of the measure is to improve the knowledge on the phenomenon of dispersion of adults and their chicks at sea and to verify if this...

Reduction and avoidance measures

2020.09-drill preparation

Photoattraction reduction in construction

The impact study highlighted that some species of flying birds were more sensitive to light than others. In the absence of measures of...
shearwater-balearic shearwater

Reducing the disturbance of the Balearic Shearwater in periods of interbreeding presence

The objective of the measure is to inform site personnel to enable avoidance of shearwater rafts by personnel transfer vessels (PTCs)...

Compensation measures

American Mink

Eradication of American Mink on the Tregor Islands - pink granite coast

The operations are part of a global project of ecological restoration of the island in the profile of the colonies of marine birds nesting. Indeed, the...

Combating the predation of seabirds by black crows

This measure implemented since 2012 aims to limit predation on seabird eggs by crows that tend to specialize on murrelets...

Improving the tranquility of marine mammals

The objective of this measure is to reinforce the quietude of marine mammals in the Gulf of Normandy Breton during the construction phase of the wind farm off the bay...

Accompanying measures

Definition and implementation of a tourist offer in collaboration with the actors of the territory.

The measure concerns the commitments made by Ailes Marines in its response to the call for tenders n°2011/S 126-208873 organized by the French State to develop a project...
goeland-brown-1

Experimenting with a collision avoidance system for birdlife

This accompanying measure concerns the experimentation of a system of avoidance of the collisions of birds with the blades of the wind turbines in operation. The system...

Turbidity modeling

AU-IOTA requires that prior to the start of work on the foundations, the project owner performs material dispersion modeling...
ailes-marines-dry eggs

Study of the impact of noise on the fisheries resource

This companion measure focuses on assessing the impact of noise on various iconic species of the fisheries resource of interest in the Bay of...
ailes-marines-sea-dolphin-and-wave

Monitoring of marine mammals by photo-identification

The objective is to contribute to the knowledge of the marine mammals in the GNB by feeding the catalog in progress by the GECC. This measure includes...
