A National Science Foundation Mid-Scale Research Infrastructure Project


The Global Ocean Biogeochemistry Array is a global robotic network of profiling floats carrying chemical and biological sensors that will revolutionize our understanding of ocean biogeochemical cycles, carbon uptake, acidification, deoxygenation, and ecosystem health.

GO-BGC utilizes autonomous robotic floats to collect temperature, salinity, pH, conductivity, nitrate, pressure, chlorophyll and optical backscatter for biological activity between 2000m depth and the surface of the ocean. Autonomous floats are well suited to this work because they capture scientific-quality measurements continuously all day for years without refueling or cancelations due to unfavorable weather conditions.  GO-BGC, part of the One Argo array, will deploy 500 autonomous floats in the world ocean between 2001 and 2006.
