Sonora expands artificial reef system with sinking of former patrol vessel

The Mexican Navy and the government of Sonora have completed the controlled sinking of the former patrol vessel ARM ‘Ángel Ortiz Monasterio’ (also referred to as the ex-buque Monasterio) near San Carlos Bay. This vessel serves as the 14th addition to the Sonora Artificial Reef System (SAAS), an initiative designed to bolster marine biodiversity and promote sustainable tourism in the Gulf of California.

The ship, which measures 67 meters in length, is intended to function as a submerged habitat. Over time, the hull is expected to be colonized by corals, algae, and seagrass, providing a refuge for species such as lobsters, sea urchins, and various fish. The SAAS currently supports over 52,000 marine individuals across 37 species.

This project is a collaborative effort between the Secretariat of the Navy (Semar), the state government, and the private sector. Beyond ecological benefits, the new structure is expected to enhance regional scuba diving tourism and provide new sites for scientific research and conservation programs.
