UNSEEN is a French non-profit organization that explores, documents, and studies Mesophotic Coral Ecosystems—at depths between 40 and 100+ meters—to advocate for their conservation. These deep-reef habitats host a wide variety of unique species, some of them endemic to these depths, and play a crucial role in coral reef resilience. Yet, due to the difficulty of access with regular SCUBA, they are poorly studied and consequently poorly protected.

The team from UNSEEN is using Closed Circuit Rebreathers to unlock access and open a window to these unique ecosystems. Gaining more knowledge and understanding of their diversity and functions is decisive for raising awareness and improving the efficiency of conservation efforts in a global context of dramatic biodiversity collapse and increasing Human pressure on the Natural world.

This expedition aims to explore unknown cave systems to uncover natural, untapped water sources, thereby reducing the community’s dependence on plastic-bottled water. By collaborating with international universities and scientists, the team will collect unique, previously inaccessible data that can contribute to global research initiatives.

Additionally, the project seeks to document the region’s geological features in support of a UNESCO geopark application, helping to preserve the area's natural and cultural heritage for future generations.
