Virgen del Carmen Marina in Marbella, Spain, in collaboration with Ocean Ecostructures, has installed six micro-reef structures within its port area to support its sustainability and efficiency programme, and to examine how nature-based structures can support marine life within an active port environment.
The structures, called “Life Boosting Units”, are designed to mirror the behaviour of natural reefs. The units have been placed within the marina basin to provide shelter and surfaces for marine species, while marina activities continue without disruption.
The marina’s director, Carlos Romero, said the project begins with a six-month colonisation period, after which regular scientific monitoring will begin. He explained that the indicators observed are expected to change according to species life cycles and seasonal patterns.
Information gathered during the monitoring phase will be used to assess how biodiversity develops around the micro-reefs. The marina plans to compile the findings into a report documenting changes over time.
The project also includes observation using remotely operated vehicles, or underwater drones, alongside data analysis tools. Romero said this approach allows close observation of how the structures are colonised and how environmental indicators evolve.
As part of the work, Ocean Ecostructures will measure impacts related to biodiversity levels, carbon dioxide capture, biomass generation and the presence of invasive species.
Ocean Ecostructures co-founder Anna Lloveras said artificial reefs are viewed as a nature-based solution with the potential to support marine biodiversity and ecosystem resilience. She added that projects developed using scientific criteria can help restore damaged habitats and provide measurable environmental results.
Marbella Marina’s facilities include a commercial area with a supermarket, pharmacy and banks, as well as restaurants, bars and a nautical club. The marina also offers fuel services, a 4-tonne crane, winter storage for vessels and nautical activities such as regattas, boat trips, sport fishing and jet ski use.
