Coral Sr/Ca calibration - An example from Dry Tortugas#

Calibration is a commonly perfomed task in paleoclimatology to relate measured proxy values to environmental variables of interest. There are several statistical methods available to do this, resulting in a somewhat confusing landscape for first-timers and non-specialists. This website covers the calibration of coral Sr/Ca to sea surface temperature using data from Dry Tortugas (DeLong et al., 2011). The website illustrates the frequentist and Bayesian approaches to the task.

Structure#

This Jupyter Book is broken down into three chapters:

  • Data exploration of the Sr/Ca data from three cores and nearby sea surface temperature data

  • Frequentist calibration using ordinary and weighted least square regression

  • Bayesian calibration presents a Bayesian alternative to OLS.

We needn’t tell you that making research tools accessible requires time and effort. If you find any of these resources useful and use them in your own research, please do us the kindness of one or more citations. Notebooks in this collection are registered on Zenodo, and associated with a digital object identifier (DOI). A ready-to-use citation is provided in this GitHub repository in APA and BibTex (in the About section on the right panel, click on “Cite this repository”). If you use Pyleoclim, please cite them as well. It will make us (and NSF!) very happy to hear that these investments spawned more research.
