Title:
Chlorophyll-a update in BGC-Argo:
What’s Changing in June 2026, How It Works, and Why It Matters?
Presenter:
Raphaëlle Sauzède
CNRS – Institut de la Mer de Villefranche
Chlorophyll-a concentration (Chla), a key indicator of phytoplankton biomass, is essential for understanding ocean ecosystems. While BGC-Argo floats have revolutionized global Chla monitoring, accurately converting fluorescence data into Chla estimates remains a significant challenge. In June 2026, a new real-time adjustment methodology will be implemented for Chla into the Argo data stream. This presentation will detail the methodology based on 4D-BGC products, the timeline for operationalization, and the broader implications of this update for ocean science and operational applications.
