What are Researchers Studying?

N3C projects are internal and user-led initiatives exploring targeted research questions within the N3C Data Enclave. Many projects are affiliated with Domain Teams, which attempt to coordinate related research efforts, enable more efficient collaboration, and provide other support to the researchers who wish to join.

What is the Scholarly Output?

Team science and attribution are central to the N3C's mission. Because of this, N3C strives to create a conducive environment for research publication by providing hands-on assistance during the manuscript preparation process and by highlighting research dissemination in both traditional and non-traditional venues, including academic journals, preprint forums, and public presentations.
