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.

Upcoming events related to the GO-BGC project including conferences, webinars, meetings, and coursework.

GO-BGC utilizes autonomous robotic floats to measure temperature, salinity, pH, nitrate, chlorophyll, suspended particles, light, and derived parameters DIC, pCO2 and total alkalinity in the ocean from the surface to 2000m. These floats can operate continuously for years in all weather conditions, providing near real-time observations of ocean biogeochemistry and ecosystems throughout the world’s oceans.  GO-BGC will deploy 500 autonomous floats in the world’s oceans between 2021 and 2026 as part of the OneArgo array. GO-BGC data are made freely available through our Data page and the Argo data system.

COP28: Observing the Changing Ocean

GO-BGC's Dr. Lynne Talley presented at COP 28. The ocean takes up more than 90% of the extra heat and 30% of the excess carbon dioxide produced by human activity that is exacerbating climate change. As a consequence, marine oxygen levels are dropping and marine...

COP28: A heated case for sustained ocean observations

GO-BGC's Dr. Lynne Talley presents at COP28. Marine heatwaves are a significant ecological and socioeconomic threat, worldwide, and have been increasing in both duration and frequency, a trend that is likely to continue. Though heatwaves at the sea surface can be...
