This repository contains the PhanSST Database of paleo-sea surface temperature (SST) proxy data spanning the Phanerozoic Eon and is associated with the manuscript:
The PhanSST global database of Phanerozoic sea surface temperature proxy data (Judd et al., accepted, Scientific Data).
Please refer to this manuscript for additional information and cite it when using data from the PhanSST database.

- 3 November 2022:
- Fixed error where SampleDepth values weren't compiling correctly with certain proxy systems
- Removed 2 references that presented seasonal rather than bulk data (Klein et al., 1997; Grossman et al., 2019)
- Added data from two new references (Babila, 2014; Brand and Bruckschen, 2002)
- Added option "2" for AgeFlag, to allow for certain data to have manually input numeric and relative age information (this is useful for data near boundaries, such as the K/Pg or PETM, whose age models might reflect older boundary date assignments)
