How to Cite EarthChem Data
To cite a synthesis database or portal, please reference its URL in text and in figure captions:
- EarthChem Portal: www.earthchem.org/portal
- PetDB: www.earthchem.org/petdb
- SedDB: www.earthchem.org/seddb
Please cite the specific download by giving the date and, if possible, parameters of the download. Here is an example for PetDB:
"The data were downloaded from the PetDB Database (www.earthchem.org/petdb) on 31 November, 2017, using the following parameters: feature name = Gakkel Ridge and rock classification= basalt."
You should also cite the original scientists who contributed to the downloaded dataset. We strongly encourage that you create a secondary bibliography for work that uses large datasets. You can easily download all of the references that contributed to a dataset for this secondary bibliography. Many journals will accept a secondary bibliography as a supplementary material file. This type of citation helps ensure that the hard work performed by members of our community is acknowledged properly.
For PetDB, you may also add this publication in the reference list: Lehnert, K., Su, Y., Langmuir, C., Sarbas, B., & Nohl, U. (2000). A global geochemical database structure for rocks. Geochem. Geophys. Geosyst. 1, doi:10.1029/1999GC000026
For SedDB, you may also add this publication to the reference list: Status Report on the SedDB Sediment Geochemistry Database: March, 2012. Johansson, A., Lehnert, K, and Hsu, L. GeoPRISMS Newsletter No. 28, Spring 2012, p. 21.
When citing data obtained from the EarthChem Library, we ask that you cite the dataset with its dataset DOI. The citation should be formatted as follows:
- Creator(s) (PublicationYear): Title. Publisher. Identifier. Data Accessed.
For example, a dataset published by IEDA in the EarthChem Library in the DOI system is Whole Rock Helium Data from ODP Site U1256D. Its data DOI is 10.1594/IEDA/100734. Its citation would be:
- Kurz, M.D.; Curtice, J. (2018): Whole Rock Helium Data from ODP Site U1256D. Interdisciplinary Earth Data Alliance (IEDA). http://dx.doi.org/10.1594/IEDA/100734. Accessed 29 March 2018.
