Obispo is a submerged reef system located approximately 140 km from the mainland at 20.50°N and 92.18°W. It is formed by plain walls or by walls fusing with inclining exterior slopes. The back reef is quite narrow, reaching depths of 50 m within a very confined space. The reef walls face southeast to northeast with the narrow portion facing windward. The reefs are relatively small; the longest wall is less than 3 km in length.
Location on Continental Shelf: Outer-Shelf Bank
Coordinates: 20.50° N 92.18° W
Nearest Largest City: Campeche, Campeche, Mexico
Length: 3.0 km
Minimum Depth: 5 m
The Holocene portions of the Campeche Bank reefs are growing atop submarine promontories that rise to 30 - 35 m, which in turn bulge from a submarine terrace that lies at 50 - 60 m. The Obispo, along with Ingleses and Triangulos groups are knolls or simple reef walls having very steep sides and small reef flats. These knolls and walls are oriented to the northeast, facing the prevalent winds and waves.
