ClumpDB


ClumpDB is a permanent, independent repository of raw (replicate-level) clumped isotope data and associated meta-data, with easy, universal access.

The partnership between the clumped isotope community and EarthChem began as part of a community-wide effort in 2019 to reprocess, compare, and reconcile published carbonate clumped isotope calibration data measured in many different labs. It was discovered as part of this project that many published papers lacked the level of information, even in supplementary material, necessary to be able to update and reprocess data using new standard values or new data processing practices. In order to facilitate future reprocessing and/or data compilation efforts and to keep older data relevant and usable as the community progresses, this EarthChem collection was created. Although initially populated with carbonate clumped isotope data (D47), this collection welcomes other clumped isotope data as well (CH4, O2, etc.).

Clumped Isotope Templates

The clumped isotope EarthChem template was designed with feedback from the clumped community. The goal of this template is to include all necessary information to convert raw replicate-level sample and standard data to final sample mean values, fully corrected into the absolute reference frame. This template is flexible, and additional columns can be added for specific variables important in a given study. 
It is highly recommended that data be uploaded using this template to make it easier to combine data from different projects in the future, however, other formats will be accepted as well.

The previous version of the clumped isotope template is available here.

Templates for other clumped isotope species are planned for the future.
