Description:
This dataset contains 48 U-Th ages of 14 speleothems used to reconstruct past sea level between 9ka and 421ka ago. They were collected from submerged caves in an area (〈20 km) around Tulum, Quintana Roo, Mexico (20.2°N, 87.5°W) at elevations between 0.0 m a.s.l and -28.7 m a.s.l. The speleothems were collected in situ and their elevation was measured with a dive computer (+-0.1m) at the base of the speleothem. Speleothem length ranges between 2 cm and 34 cm. The measurements were carried out by a multi-collector inductively coupled plasma mass spectrometer (ThermoFisher Neptune Plus).
