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.
