| contents | This dataset contains the raw clumped isotope individual measurements (Δ47) of pure coccolith calcite from ODP Site 982 in the North Atlantic between the Mid Miocene and the Quaternary (16-1.99 Ma; 524.55-43.99 m (mcd)), and pure Coccolithus pelagicus from a sediment trap sample in the Iceland Sea (70.23° N; 9.75° W; 1884 m) (Mejia et al., 2025;doi:10.21203/rs.3.rs-6393158/v1). We measured clumped isotopes using a Kiel IV-Thermo Scientific MAT 253 at ETH Zürich, following the LIDI protocol (Müller et al., 2017; doi:10.1002/rcm.7878), including a Porapak Q trap (-40 °C) to eliminate residual halo/hydrocarbon and reduced sulfur compounds. Nine to 21 replicates of ~110 μg carbonate were measured depending on sample availability. Carbonate standardization followed the use of carbonate standard scheme (I-CDES (InterCarb carbon dioxide equilibrium scale; LIDI protocol (Bernasconi et al., 2021; doi:10.1029/2020GC009588)). Contaminated replicates were eliminated from the dataset when the Δ48 offset was > 2 and 49 parameter values > 2 ‰ (included in this dataset), which is considered a standard protocol in clumped isotope measurements. |
