This repository contains the source code for the online δ18O-temperature converter tool described in:
Gaskell, D.E., and Hull, P.M., 2023, Technical note: A new online tool for δ18O–temperature conversions: Climate of the Past, v. 19, p. 1265–1274, doi:10.5194/cp-19-1265-2023.
The current official online host for the tool is https://research.peabody.yale.edu/d180/. An alternate host is also available at https://www.danielgaskell.com/d18O. This tool may be freely used to generate data for publications provided this publication (or its subsequent version of record) is appropriately cited.
Follow-up release for publication.
- Added a workaround for servers which refuse GPlates' certs
- Refactored linear interpolation routine for ~4x performance increase
- Removed reformulation notices from some calibrations where coefficients were identical to the original publication
- Minor typo corrections
Follow-up release for review.
- Added option to download citations as BibTeX
- Added Meckler et al. (2022) δ18Osw and temperature records
- Added column definitions to output
- Added option to select d18Osw_spatial points by great circle distance
- Added number of points averaged and standard deviation to output of d18Osw_spatial methods
- Rephrased methods output to better clarify reformulations
- Deprioritized "outside calibration limits" error when other errors are present
- Versioning system
- Fixed minor typos
- Changed the algebraic format of alpha-based calibrations to more precisely match the format given in the paper
- Removed Zhou & Zheng (2003) aragonite calibration due to uncertainties about which standard conversions should be used with this calibration
- Corrected an issue with the assumed timescale of Rohling et al. (2021) data
- Changed a few default selections to reduce server load
Initial release for preprint.
