A survey was carried out in the marine area southwest of Puerto Morelos, specifically in the area that corresponds to the Puerto Morelos Arrecife National Park. In order to study the marine currents and the associated phenomena, a route was made from the coast towards the open sea, up to approximately 2 km, a value far from that proposed in the planning because the climatic conditions were not favorable. This tour was carried out on September 11, 2019 in the morning, lasting approximately 2 hours, where measurements were made at 6 stations; From station 3 the swell began to be noticed, stations 4 and 5 were located inside the reef and the sixth station was on the dock. The variables measured were: temperature, wind direction and speed, relative humidity and turbidity. The CTD measurements were processed using contour & surface-mapping software surfer 8 to generate temperature profiles, and a map of the course was created in QGIS with the coordinates recorded with the GPS. Measurements of wind speed and direction made it possible to explain its influence on the general circulation of the sea surface.
