As planning for the Simons Collaboration on Computational Biogeochemical Modeling of Marine Ecosystems (CBIOMES) took off in January 2017, one need quickly became apparent: a database with tools that would allow the project’s participants to sift through the mountains of oceanographic data collected from their own work and by other initiatives. Introducing: The Simons Collaborative Marine Atlas Project (CMAP) — an open database that merges CBIOMES data with publicly available datasets from satellites and sensors and, more recently, all the other oceanographic research initiatives supported by the Simons Foundation.
