A Comprehensive Oceanographic, Meteorological and Hydrographic Dataset for the San Andres, Providencia, and Santa Catalina Archipelago in the Colombian Caribbean, 2018–2025

This dataset contains multi-sensor oceanographic, hydrographic, wave, and meteorological observations collected across the San Andrés, Providencia, and Santa Catalina Islands (Colombian Caribbean) between May 2018 and July 2025.
Sea surface variation was measured using AQUAlogger and RBR pressure sensors (SV, ASV), and additional surface-variation products and vertical current profiles were obtained from Nortek AWAC Acoustic Doppler Current Profilers (600 and 1000 kHz) (SVC). Fixed-depth time series of seawater temperature and temperature–conductivity were recorded with HOBO loggers (TCL), while CTD casts provided vertical profiles of temperature, conductivity, salinity, density, specific conductance, and sound velocity (CTD). Offshore wave parameters were measured using a Spotter wave buoy (WB).

Atmospheric variables—including air temperature, humidity, barometric pressure, precipitation, solar radiation, and wind speed and direction—were recorded by Davis Vantage Pro, Rainwise, and WeatherSens stations installed on San Andrés Island. All instruments were deployed following standard coastal-monitoring procedures, ensuring quality-controlled observations suitable for studies of coastal hydrodynamics, hydro-climatic variability, and environmental change in tropical island systems.
