Abstract The interpretation of stalagmite δ18O in terms of reflecting Asian summer monsoon (ASM) precipitation is still elusive. Here, we present high‐resolution stalagmite trace element ratios (X/Ca, X = Mg, Sr, Ba) records from southwest China c

Human presence on the Yucatán Peninsula reaches back to the Late Pleistocene. Osteological evidence comes from submerged caves and sinkholes (cenotes) near Tulum in the Mexican state of Quintana Roo. Here we report on a new skeleton discovered by us

Speleothems, secondary cave carbonate precipitates, can serve as tools to reconstruct past terrestrial ecosystem processes, particularly related to soil and vegetation. Radiocarbon, often in conjunction with other geochemical proxies, has been increa

The Little Ice Age (LIA), a multicentennial period of predominant anomalously cold conditions on Earth, is among the most important periods that characterized climate evolution during the pre-industrial part of the last millennium. However, LIA remai

Interpreting carbon isotopes in speleothems is challenging due to the multiple interacting in-soil and in-cave chemical processes. The degree of free soil CO2, the relative abundance of aged soil organic matter (SOM) and bedrock dead carbon modifies

Here we show preliminary cave monitoring and speleothem results from Erdmannshöhle in Hasel, one of the oldest show caves in Germany. The comprehensive monitoring programme of drip water and cave air started in late summer 2022 and is still ongoing.

This research is based on broader study investigating drivers of decadal to centennial-scale variations in the Central American Monsoon (CAM), a sub-region of the broader North American Monsoon. In the context of the Global Monsoon system, the precip

Carbonate based archives, such as speleothems and cold-water corals, yield valuable information on past states of the climate system. The key chronometer to access the deposition times of these archives is 230Th/U dating, typically measured using mul

Hells Bells are underwater secondary carbonates discovered in sinkholes (cenotes) southeast of Cancun on the north-eastern Yucatán Peninsula, Mexico. These authigenic calcite precipitates, reaching a length of up to 4 m, most likely grow in the pela
