TEX86 is an important proxy for constraining ocean temperatures in the Earth's past. Here we develop and apply a Bayesian regression approach to the SST-TEX86 calibration that explicitly allows for model parameters to smoothly vary as a function of space. Applications to both Quaternary and Eocene TEX86 data demonstrate that our approach produces improved predictions and allows for probabilistic assessments of past temperatures.
