What is the 1-click preprint transfer service? ESS Open Archive supports the early and open sharing of Earth and space science research outputs as preprints before or concurrent with submission to a participating journal so that researchers can showcase their work to the global Earth and space science community while it is under consideration at a journal. The transfer service is in an initiative to streamline the process: authors can now seamlessly transfer their manuscript to ESS Open Archive at the same time they submit their research to a participating journal and save time re-uploading files and re-entering information to submit a preprint.
