Description

Water isotopes have been used for building our current understanding of the distribution and amounts of renewable and non-renewable groundwater. In this research we compiled published and unpublished δ2H and δ18O data in meteoric, groundwater and pore water, to obtain a regional meteoric water line of the Peninsula of Yucatan, Mexico (RMWL). All data was organized following the template of the GNIP including location (state), geographic coordinates (decimal degree), authors, type of water reported (meteoric, groundwater, sea, lake), date (month-year) δ18O, δ2H, d-excess, altitude (m above sea level), aquifer, historical annual precipitation (in mm), soil type, hydrogeological sub-region, geology (type and class) and analyses providers (Supplementary Material 1). We also examine evaporation lines by plotting the groundwater isotope composition considering the states geopolitical division; in cases where only δ18O was reported, we used the equations obtained from evaporation lines for each state in order to interpolate nonexistent or not reported δ2H data (Supplementary Material 2).

Steps to reproduce

We data mined published papers, dissertations, proceedings, databases and websites together with unpublished data regarding the isotopic composition of water (δ2H and δ18O) in the three states of Mexico comprising the Peninsula of Yucatan: Campeche, Quintana Roo and Yucatan. Datamining was focused on water isotopes only, not including data from sediments, shells or other matrices.
