| Objective | The CREPIT cruise aims to answer the following 3 questions: 1. What is the recent evolution of crepidula proliferation in the Bay of Saint-Brieuc? 2. How does the structure of an impacted benthic community evolve, re the specific and functional biodiversity (i.e. in terms of the complexity of trophic interactions), with increasing density of crepidula on the seabed? 3. What impact will the offshore wind farm in the Bay of Saint-Brieuc have on the proliferation of crepidula? The related project is "Benthic habitats". The project's study area is located in the eastern part of the Bay of Saint-Brieuc. An approach using sonar, video and grab samples was made on a sector (50km2) already studied in 2005. It is located in the eastern part of the bay, called the Comtesses zone, near Erquy where water depths do not exceed 20m. Plankton net hauls were made in the southern part of the zone of a future offshore wind farm, to the north of Erquy. |
