| Summary: | Raw data and Python scripts for: Variability of dissolved inorganic carbon in the largest karst estuarine lagoon system of the southern Gulf of Mexico In: Estuaries and Coasts: Resilence to global change in SGOM Authors José Andrés Martínez-Trejo Jose-Gilberto Cardoso-Mohedano Joan Albert Sanchez-Cabeza José Martin Hernández Ayón Ana Carolina Ruiz-Fernández Mario Alejandro Gómez-Ponce Linda Barranco-Servín Daniel Pech Corresponding Author: gcardoso@cmarl.unam.mx Our data collection was thorough. Water samples were collected from the Terminos Lagoon at coordinates 18°01'54"N, 90°59'15" W during the dry seasons of February 2020 and March 2021 and the rainy season of November 2021. The samples were collected along two transects, each with nine stations, spanning from the Palizada and Candelaria Rivers to the coastal area. Total alkalinity (TA) was measured via potentiometric titration, while dissolved inorganic carbon (DIC) was measured by coulometry. The ΩAr, pH, and pCO2 calculations were performed using PyCO2SYS 2.0. Furthermore, we determined the apparent oxygen consumption (AOU) and TA–DIC to assess carbonate biogeochemical processes.
