GEOTRACES Publication Best Practices

 ✓ Please include “GEOTRACES” in either the title, abstract or keywords of your GEOTRACES publications.
 ✓ Intermediate Data Product (IDP) data contributors: Please use the DOoR portal to add any new publication of your data included in the IDP.
To facilitate future synthesis activities (and database searches), we strongly encourage you to select in the DOoR form (dropdown menu) the process your publications address.

 ✓ Please help us to acknowledge support from SCOR in your publications as follows: 
“The International GEOTRACES Programme is possible in part thanks to the support from the U.S. National Science Foundation (Grant OCE-OCE-2513154) to the Scientific Committee on Oceanic Research (SCOR).”
