Local hydroclimate alters interpretation of speleothem δ 18O records [PDF]
Nature CommunicationsOxygen isotopes (δ 18O) are the most commonly utilized speleothem proxy and have provided many foundational records of paleoclimate. Thus, understanding processes affecting speleothem δ 18O is crucial.

Speleothem Paleoclimatology for the Caribbean, Central America, and North America
Quaternary, 2019 Speleothem oxygen isotope records from the Caribbean, Central, and North America reveal climatic controls that include orbital variation, deglacial forcing related to ocean circulation and ice sheet retreat, and the influence of local and remote sea ...

StalGrowth—A Program to Estimate Speleothem Growth Rates and Seasonal Growth Variations
Geosciences, 2021 Speleothems are one of the few archives which allow us to reconstruct the terrestrial paleoclimate and help us to understand the important climate dynamics in inhabited regions of our planet.

Evaluating model outputs using integrated global speleothem records of climate change since the last glacial [PDF]
Climate of the Past, 2019 Although quantitative isotope data from speleothems has been used to evaluate isotope-enabled model simulations, currently no consensus exists regarding the most appropriate methodology through which to achieve this.

Controls on Speleothem Initial 234U/238U Ratios in a Monsoon Climate
Geochemistry, Geophysics, Geosystems, 2023 Speleothem initial uranium isotope ratios ((234U/238U)i) can be influenced by processes along the seepage water flow‐path including alpha‐recoil into porewater during 238U decay and hostrock weathering, the balance of which can reflect the infiltration ...

New online method for water isotope analysis of speleothem fluid inclusions using laser absorption spectroscopy (WS-CRDS) [PDF]
Climate of the Past, 2014 A new online method to analyse water isotopes of speleothem fluid inclusions using a wavelength scanned cavity ring down spectroscopy (WS-CRDS) instrument is presented. This novel technique allows us simultaneously to measure hydrogen and oxygen isotopes

Multiscale monsoon variability during the last two climatic cycles revealed by spectral signals in Chinese loess and speleothem records [PDF]
Climate of the Past, 2015 The East Asian Monsoon (EAM) exhibits a significant variability on timescales ranging from tectonic to centennial as inferred from loess, speleothem and marine records.
