Raw clumped isotope sample and standard data of modern and fossil Cittarium pica from Bermuda for manuscript submission titled \"Seasonally Variable Aquifer Discharge and Cooler Climate in Bermuda during the Last Interglacial Revealed by Subannual Clumped Isotope Analysis\"

In this dataset, we present new, subannual-scale clumped isotope measurements on five of the ten C. pica shells from the original Winkelstern et al., 2017 study (1 modern, 2 fossils from DB/RB, 2 fossils from GB) to investigate the seasonal persistence and timing of interglacial cooling in Bermuda and determine whether inter-site differences may have been the result of seasonal sampling bias. Published clumped isotope data from Winkelstern et al. (2017) were recalculated using improved data processing techniques (IUPAC/Brand parameters; see Petersen et al. 2019) for more accuracy and to enable better comparison with new data.
