Ecological and Community Benefits for St Maarten
Our unique and impactful project in St Maarten not only provides a unique snorkeling experience, but also benefits the local community and the wider marine environment.
Finding the right balance
Staying true to the unique spirit of St Maarten
Under SXM is driven by a strong purpose; that of harmony. We're passionate about creating a balance between the needs of the local community and the needs of the island's marine life.
Reef Sculptures
Using the Right Materials
Our sculptures are made with an inert, pH neutral artificial reef compound. This provides a stable substrate for coral, sponges and biomass to settle. These special habitats were created to provide homes for the local marine species to seek comfort.
Making a difference
The Positive Ecological Impact of our Sculptures
Our artificial reef does more than showcase art. It's a carefully designed marine sanctuary. By integrating species-specific habitat spaces within the sculptures, we've created a protective zone where marine life can thrive. This innovative approach helps reduce tourist pressure on St Maarten's natural reefs while providing an engaging way to connect visitors and the local community with marine conservation efforts.
Bringing people together
The Vibrant Soul of St Maarten
Every sculpture in our underwater gallery was literally life cast and a handpicked member of St Maarten's vibrant community, making them an integral part of this unique project. The revenue generated from visitors exploring our marine park is purposefully reinvested back into the local community, with a special focus on ocean education and conservation initiatives.
An immediate hit with the marine life
Early Days on the Reef
It didn't take long for the local marine life to take to the artificial reef. The sculptures were an instant hit, providing protection, refuge and a source of food for a range of marine life. As time has gone on, coral and plant grow has thrived and more characters come to visit.
