Follow-up actions

Visual monitoring of marine mammals and birds

Objectives and methodology

The main objective of "visual" monitoring of marine mammals and birds is to determine the impact of the work and operation of the wind farm of the Saint-Brieuc bay on these groups. This monitoring will also help improve local knowledge. These were communicated to the SMC in April 2019.

Vessel observations are carried out by two observers simultaneously, each covering one side of a vessel and concentrating on a 300 m strip.

A transect protocol is also deployed for high definition aerial tracking. Films made during releases are analysed back on land.
