Many scientists around the world are studying marine biodiversity—the variety of life forms in the ocean. But there is no common standard for how to conduct this research or to compile the data from different studies in different areas. MBARI’s Francisco Chavez, a biological oceanographer, and his collaborators have been developing an international collaboration to fill these gaps and collect biological measurements across diverse marine ecosystems. The researchers discussed their new Pole-to-Pole Marine Biodiversity Observation Network (P2P MBON) this week at the American Geophysical Union Fall 2018 meeting in Washington, D.C.
