Four prototype reefs will be installed, each built from reused building materials and low-impact concrete blends, including experimental aircrete and oyster shells for texture and carbon reduction. The structures are modular, easy to deploy and remove, and designed to support seaweed planting later.

Species & Habitat Goals

The reefs are intended to attract:

• Kelp (sugar kelp)

• Mussels, sea urchins, crabs, lobsters

• Starfish, anemones

• Various fish species

Invasive species like Pacific oysters will be monitored and removed where possible.

Research & Community

The project follows guidelines from NIVA (Norwegian Institute for Water Research) and collaborates with NTNU and other researchers. It also activates FCU’s and Marea’s volunteer network for monitoring, maintenance, and citizen science, while creating new opportunities for education, snorkelling, and diving.
