Advancing Ocean Monitoring with Data Assimilation
New research shows that merging biogeochemical observations with models improves the simulation of phytoplankton phenology and reduces uncertainty in plankton community structure & production. However, chlorophyll assimilation may increase uncertainty in trophic efficiency & POC.
The study highlights the need for controllability assessments as a standard practice in operational ocean modeling, ensuring more accurate ecosystem indicators for marine monitoring & climate studies.
