Nuevo is a submerged reef, located close to the continent at 20.51°N and 91.84°W. Its origin, like many other reefs in the Campeche Bank, is unknown. It is an extensive reef, reaching a maximum depth of 46 m. Around the depth of 43 m it rises to 39 and then 14m.
Location on Continental Shelf: Outer-Shelf Bank
Coordinates: 20.51° N 91.84° W
Nearest Largest City: Campeche, Campeche, Mexico
Minimum Depth: 14 m
Maximum Depth: 46 m
A moderately dense community exists between 30-40 m to 20-25 m in depth. It is dominated by Agaricia agaricites and Montastrea sp., along with calcareous algae of the genus Lithothanium. From this point onto the 10 m depth range, a community exists mainly composed of Montastrea sp., Porites astreoides, Diploria sp. and hydrocorals of the genus Millepora. The dominant species of this area are the Palythoa caribaeorum and Zoanthus sociatus sea anemone colonies. Differentiated reef crests are not present in the bank.
The origin of Banco Nuevo has not been determined, but its distribution pattern suggests that it is a preholocene reef structure, similar to the emergent banks. In this case, it is probably a coral community that was not able to keep up a growth rate fast enough to compensate for the rise of sea level during the Holocene transgression, and/or was unable to reach the surface afterwards, when the rate of sea level rise declined.
