TL;DR
- Caprera Canyon, off the coast of Sardinia, Italy, is a large and biodiverse underwater ecosystem vital for nutrient cycling and carbon storage.
- Exploration using a remotely operated vehicle (ROV) revealed diverse marine life, including rare sponges, corals, and fish, but also significant pollution and discarded fishing gear.
- Threats to the canyon include commercial fishing, high maritime traffic, and pollution, which endanger marine species and habitats.
- Researchers are gathering data, including environmental DNA sampling and hydrophone recordings, to support the designation of Caprera Canyon as a Marine Protected Area (MPA).
- Encouraging discoveries include the presence of the endangered Mediterranean monk seal, suggesting the canyon is an important feeding ground.
- The One Ocean Foundation aims to secure multiple layers of protection, including Important Marine Mammal Area (IMMA), Fisheries Restricted Area (FRA), and MPA recognition.
