POSEIDON Benthic Storyboard

Abstract

POSEIDON (Planning Offshore wind Strategic Environmental Impact DecisiONs) is a Crown Estate funded project (2022–2026) managed through OWEC (Offshore Wind Evidence and Change Programme).

The project, led by Natural England, aims to provide tools to inform offshore wind planning, to minimise impacts on the natural environment through avoidance and early awareness of likely mitigation/compensation needs, allowing sustainable expansion of offshore wind.

This was achieved through the collection of strategic environmental baseline data and updated spatial models for key ecological receptors. These models were used to identify regions that are most vulnerable to offshore wind impact. Mapping environmental risk in this way helpS guide future offshore wind development rounds and wider marine planning.

POSEIDON focuses on two key receptor groups:

  • Highly mobile species (seabirds and marine mammals) — led by Natural England with sub-contractors at Bangor University and the University of St Andrews.
  • Benthos (seabed invertebrate species and assemblages) — led by Cefas.

This storyboard relates to the benthic work undertaken by Cefas.
