Trace element and stable isotope data of subaqueous grown speleothems (Hells Bells) from the northeastern Yucatán Peninsula

This dataset provides geochemical data (trace elements and stable isotopes) of subaqueous grown speleothems (Hells Bells) from the north-eastern Yucatán Peninsula. These secondary carbonates were collected from three different sinkholes (cenotes) southwest of Cancún, Quintana Roo, Mexico (20.51–20.52°N, 87.01–87.07°W) at water depths between -29.4 m a.s.l and -37.3 m a.s.l. Samples were collected in situ and their elevation was measured with a dive computer (+-0.1m). For samples taken from the bottom of the cenotes, we cannot assign a corresponding water depth since we have no information about their original position on the cave ceiling. Major and trace elements were determined by ICP-OES. Stable carbon and oxygen isotope measurements were carried out by a ThermoFinnigan MAT253Plus gas source mass spectrometer equipped with a Thermo Fisher Scientific Kiel IV carbonate device.
