A Comprehensive Oceanographic, Meteorological and Hydrographic Dataset for the San Andres, Providencia, and Santa Catalina Archipelago in the Colombian Caribbean, 2018–2025
Description
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.
Files
Steps to reproduce
The dataset is organized within the data directory and divided into two main folders: Raw and Filtered. The Raw folder contains the original files exactly as exported by each instrument in their native formats (e.g., .csv, .txt, .rsk, and proprietary logger outputs), without temporal trimming or quality filtering. These files preserve complete sensor exports, including configuration metadata and records acquired outside effective in-water deployment periods, and are intended for users requiring full outputs for custom processing. The Filtered folder contains standardized, quality-controlled versions of the same datasets, restricted to the effective deployment intervals and formatted consistently across all sensors to facilitate cross-comparison and multi-sensor analyses. These files include only in-water measurements, with non-essential metadata removed and variables presented in simplified, standardized tabular formats for direct scientific use. Within both Raw and Filtered, the data are subdivided into two geographic folders: San_Andres and Providencia-Santa_Catalina. Each island-level folder contains thematic subdirectories corresponding to the different data types included in the study. Files are stored in plain-text formats and follow a standardized naming convention: XY_mmyy, or XY-Z_mmyy when multiple measurements were collected at the same location during the same month, where X denotes the data-type abbreviation, Y identifies the measurement location, Z represents a sequence number (if applicable), and mmyy indicates the month and year of collection.
