This datasets includes all the CTD profiles taken by the scientific teams on-board the RV Belgica during the year 2022-2024. The vast majority of the profiles are measured in the Belgian part of the North Sea.

This set of CTD measurements places the fresh water discharge into the sea, which is located in Punta Esmeralda in the City of Playa del Carmen, State of Quintana Roo, in the Mexican Caribbean Sea. For these measurements two measuring instruments were used; a CTD for temperature and salinity profiles and a USGS type AA current meter to measure discharge to the sea, applying two methodologies for the measurement of volumetric flow according to FAO, (2009). Punta Esmeralda is a beach site that has three springs on the beach which form a freshwater lagoon about 60 meters long by 25 wide and a deep part of 1.6 meters. This lagoon is located at the coordinates 20.648372 ° N 87.050909 ° W. The discharge of water forms a small stream with a stream 6 meters wide with a bathymetric profile with a maximum depth of 0.40 m. These dimensions change over time due to natural and artificial processes. The fresh water discharge to the sea has an average flow of 0.2142 m3 /s , at an average speed of 0.1305 m /s. The sampling points with the CTD were a total of 61 and were distributed throughout the lagoon, the output of the three largest springs and a small "cenote" that is located about 76 meters away from the beach, were also performed sampling points in the sea at a distance of 100 meters from the coast and 2 meters deep. The salinity ranges measured in the springs was 4 UPS and it was increasing to the sea with 35 UPS. With temperatures in the springs from 25.8 ° C to 30.8 ° C in the sea.   Important Note: This submission has been initially submitted to SEA scieNtific Open data Edition (SEANOE) publication service and received the recorded DOI.

This campaign was carried out on May 15, 2021 on the route between Puerto Juárez and the Arrowsmith Bank course or “Bajo del Este”, as the fishermen call it. The bank is located 40 km east of Punta Cancun at coordinates 21°05'00''N-86°28'00''W. The ship's captain Guillermo Antonio Carrillo Corzo alias the "Teacher", a pilot (Cap. Watermelon) and a sailor (El Chalán). The goal was carry out temperature and salinity measurements in the water column at each of the CTD stations. Direction: 10 stations with a separation of 4 km between each one were planned. Stations 1 to 6 were covered without difficulty; however, at station 7 the waves and the current increased their intensity considerably, so no progress was made to the following stations. the diagram salinity temperature profiles of each station (aligned West to East) The salinity is between 35 and 36 UPS and in turn from 28 °C to 25.5 °C. The depth ranges at the stations were from 1 to 57 m deep.
