Biotope produced the “Rapport final de campagnes sur la mégafaune marine 2024” for the Centre Manche 1 offshore wind project study area off Normandy. The report was listed among the project’s baseline environmental (“état initial de l’environnement”) deliverables made available for the zone, and it formed part of the wider programme of environmental and use studies that supported the project’s early development and impact assessment process. The work related specifically to marine megafauna, covering offshore field campaigns and the compilation and interpretation of collected data into a final 2024 report. Within the broader baseline programme described for Centre Manche 1, these activities sat alongside other environmental compartments (e.g., benthos, water/sediment quality, fish, underwater noise) and were intended to characterise existing conditions in the project area before construction. This type of deliverable is typically used to inform environmental impact assessments, mitigation planning, and ongoing stakeholder and regulatory discussions. No contracting entity, contract date, or contract value was stated in the source for Biotope’s report production, and no physical component quantities were associated with this role in the cited material.
