Through a collaborative work Universidad del Caribe-Isla Contoy National Park, the first oceanographic campaign was carried out in shallow waters within the Park's polygon and was carried out by UNICARIBE-PNIC / COIXLACHÉ-03/2016, with the aim of collecting oceanographic data of scientific importance for the various areas of knowledge for conservation. The Isla Contoy National Park is a Protected Natural Area located in the municipality of Isla Mujeres, Quintana Roo. It has a total area of ​​5,126 hectares, of which 375 hectares of the marina were covered in this study. 175 measurement points were established, distributed throughout the 4 kilometers of the study area. Measurements of pH, conductivity, temperature and pressure were made. These measurements were made in May 2016. Using the SUFER 12® Program, the data was processed to make three-dimensional models and contour models. The topographic relief is maintained at a depth of between 1 and 3 meters on the west side of the reef ridge with the exception of two depressions found. In the east a decline was found that culminated at 9.5 meters. The salinity remains within the limits established for the oceans and the temperature ranges between 25 and 29 ° C. The normal conditions of pH of the ocean water lies in 8.1 units, the average of the measurements carried out in this study shows a pH of 7.7 units. This report is based on the information contained in the database COIXLACHÉ-03/2016 Framed in the social service of the Laboratory of Environmental Technologies of the Universidad del Caribe and through research activities without collection or examples of species not considered at risk in protected natural areas CNANP-00-008.
