R2R+BCO-DMO – Linked Oceanographic

ment Office (BCO-DMO) and the Rolling Deck to Repository (R2R) program are two key data repositories for oceanographic research, sup-ported by the U.S. National Science Foundation (NSF). R2R curates dig-ital data and documentation generated by environmental sensor systems installed on vessels from the U.S. academic research fleet, with support from the NSF Oceanographic Technical Services and Arctic Research Logistics Programs. BCO-DMO human-curates and maintains data and metadata including biological, chemical, and physical measurements and results from projects funded by the NSF Biological Oceanography, Chem-ical Oceanography, and Antarctic Organisms & Ecosystems Programs. These two repositories have a strong connection, and document several thousand U.S. oceanographic research expeditions since the 1970’s. Re-cently, R2R and BCO-DMO have made their metadata collections avail-able as Linked Data, accessible via public SPARQL endpoints. In this paper, we report on these datasets.
