Stable isotopic data (O, C) for stalagmite BZBT1, Cayo, Belize

BZBT1 is a 93 mm tall stalagmite that was collected on May 11, 2010, in a middle passage of Box Tunich Cave, Cayo District, Belize (17.090°N 88.947°W, 335 m a.s.l.). The stalagmite was sampled for oxygen and carbon stable isotopes at overlapping depths to produce a continuous isotopic record of 188 samples. Each sample in this dataset contains values for sample depth from the stalagmite top in millimeters (depth_mm), ages in years before present (present = 1950) for three different chronological models (yrBP_linear_untuned, yrBP_tuned_yokg, yrBP_tuned_yoki), and oxygen and carbon stable isotopic ratios reported as permill versus V-PDB (d18O, d13C). The three chronological models are a linear model reported in Akers et al., 2019 (https://doi.org/10.1177/0959683619838047), a model more closely tuned to tie points in the YOK-G stalagmite record (https://doi.org/10.1126/sciadv.aax3644), and a model more closely tuned to tie points in the YOK-I stalagmite record (https://doi.org/10.1126/science.1226299).
