We were sub-contracted to conduct a benthic characterisation survey within the planned array area and cable route for an offshore wind farm (OWF) in the Baltic Sea.
The surveys were designed to identify sensitive seabed habitats and associated biota while establishing a baseline dataset for sediment composition, macrofaunal communities, and particulate carbon traces. This information was essential in informing environmental assessments and guiding future offshore development.
Survey scope and methodology
To achieve these objectives, we:
- Provided marine mammal observers and passive acoustic monitoring to support acoustic survey operations and ensure compliance with mitigation measures.
- Conducted an initial seabed habitat and sediment assessment, ground-truthing geophysical data to ensure optimal grab sampling locations.
- Utilised a drop-down camera to document seabed features and validate survey findings.
- Acquisition of macrofaunal, particle size distribution and chemical samples for analysis at our NMBAQC-participating laboratory.
Outcomes and reporting
Following the successful completion of the fieldwork, we produced key deliverables, including the habitat assessment, site characterisation, and marine mammal mitigation reports. These outputs contributed valuable ecological insights for the project, supporting regulatory approvals and sustainable offshore wind farm development.
This project highlights our expertise in offshore survey operations and commitment to minimising environmental impacts in support of renewable energy infrastructure.
