What is open-access data?

“Open access data is data that is available to use at no cost, freely accessible, and downloadable” (McMaster University [MU], 2022).


PANGAEA is a long-standing open-access repository that provides anyone with access to credible environmental science data from around the globe. Specifically, this repository “has an almost 30-year history as an open-access library for archiving, publishing, and disseminating georeferenced data from the Earth, environmental, and biodiversity sciences” (Pangea, n.d.).

PANGAEA is hosted by Alfred Wegener Institute’s Helmholtz Centre for Polar and Marine Research and the University of Bremen’s Center for Marine Environmental Sciences (Registry of Research Data Repositories [RRDR], 2022).
