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.

How are Scientists Keeping an Eye on Earth’s Oceans?

The ocean is very important to human wellbeing because it provides us with food, medicines, transportation, recreation, and homes for many marine (ocean) species. To study the ocean, scientists must consistently collect data for many years. One important way to get this information is to go on ships to take measurements. But there are places that are difficult for ships to get to, such as the Arctic and the Antarctic, and seasons that make travel impossible. To collect measurements from Earth’s oceans in all seasons and many more places than ships usually go, scientists invented Argo robots.
