For example, it provides crucial insight into past ice-volume variations, an important climate system feedback. Moreover, deep-sea temperature is important to deep-sea ecology and biogeochemical cycling. Here we compare deep-sea temperature and sea-water oxygen isotope ratios from model-based deconvolution of benthic foraminiferal carbonate δ</span><sup>18</sup><span style=\"background-color:rgb(255,255,255);color:rgb(0,0,0);\">O with clumped isotope-based deep-sea temperature data in 1000-year timesteps over the Cenozoic. To assess wider implications of the observed differences, we quantitatively evaluate a range of potential explanatory hypotheses—such as diagenetic overprints, carbonate ion effects, ice-sheet morphology changes, and warm saline deep-water admixture—but find that, individually, none can explain the observed differences satisfactorily. We then evaluate the implications of possible combined effects and recent advances in clumped isotope temperature calibration. We find that combined consideration of a recently proposed cool clumped isotope calibration and possible carbonate ion or pH influences can provide results that approximate deep-sea temperature reconstructions based on conventional δ</span><sup>18</sup><span style=\"background-color:rgb(255,255,255);color:rgb(0,0,0);\">O</span><sub>c</sub><span style=\"background-color:rgb(255,255,255);color:rgb(0,0,0);\"> deconvolution. The match can be further improved if modest warm saline deep-water contributions are considered during past warm periods. This contrasts with ice-volume and ice-sheet morphology changes, which appear unrealistic or insignificant, respectively.
