+publicationAbstract: Lacustrine, riverine and spring carbonates represent
+  archives of terrestrial climates and their geochemistry has been used to study
+  palaeoenvironments. 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.
