Tracking the Ocean’s Vital Signs with BGC-Argo: From Regional Studies to Global Processes
Session ID#: 254057
Session Description:
Biogeochemical Argo (BGC-Argo) is developing a global network of biogeochemical sensors that is transforming our ability to observe and understand ocean biogeochemistry. These floats provide high-resolution data across space and time, including from regions and seasons that have historically been difficult to access, such as the Southern Ocean and the centers of subtropical gyres. This session invites contributions that use BGC-Argo data to explore a wide range of oceanographic phenomena and processes. We welcome studies from all regions and disciplines that utilize such observations, whether alone or in combination with other observations or models, to investigate the state and variability of ocean biogeochemistry. Submissions may include observational analyses applying single or multiple float datasets, data integration efforts, biogeochemical modeling, applications to climate and ecosystem studies, and methodological advances. We also welcome studies that examine processes such as, but not limited to, air-sea fluxes, ocean acidification, deoxygenation, nutrient cycling, and biological production. The goal of this session is to bring together a diverse community of researchers using BGC-Argo observations to advance our understanding of ocean biogeochemistry and ecosystem health.
