Clumped isotope thermometry is an emerging tool that has + been applied to freshwater carbonates. Limited work has been done to evaluate + comparative relationships between clumped isotopes and temperature in + different types of modern freshwater carbonates. This study assembles an + extensive calibration data set with 135 samples of modern freshwater + carbonates from 96 sites and constrains the relationship between independent + observations of water temperature and the clumped isotopic composition of + carbonates (denoted by Δ47), including new measurements, and recalculates + published data in accordance with current community-defined standard values. + For temperature reconstruction, the study reports a composite freshwater + calibration and material-specific calibrations for biogenic carbonates + (freshwater gastropods and bivalves), fine-grained carbonate (e.g. micrites), + biologically mediated carbonates (microbialites and tufas) and travertines. + Material-specific calibration trends show a convergence of slopes that are in + agreement with recently published syntheses, but statistically significant + differences in intercepts occur between some materials (e.g. some biogenics, + fine-grained carbonates). These differences may arise due to unresolved + seasonal biases, kinetic isotope effects and/or varying degrees of biological + influence. The impact of different calibrations is shown through application + to new data for glacial and deglacial age travertines from Austria and + published data sets. While material-specific calibrations may yield more + accurate results for biogenic and fine-grained carbonate samples, the use of + material-specific and the composite freshwater calibrations generally produces + values within 1.0–1.5°C of each other, and typically fall within calibration + uncertainty given limitations of precision. +tags: + - Data science + - Geosciences + - Paleoclimatology +image: /assets/images/publications/screenshot-2024-10-14-at-11.31.44-pm.png +pdfDocument: /assets/documents/publications/arnoldetal_2024.pdf +webLink: https://onlinelibrary.wiley.com/doi/full/10.1002/dep2.312 +---
