OB44C:
Biogeochemistry in the BGC-Argo Era: From Process Studies to Ecosystem Forecasts II Posters

Session ID#: 84942

Session Description:
Fostering the establishment of a global ocean observing system, Walter Munk defined the twentieth century as the “century of undersampling”, and this is true especially for marine biogeochemical data.

Biogeochemical-Argo is bringing us into a new era that is characterized by an unprecedented availability of high-resolution biogeochemical profiles, delivered throughout the year and globally distributed. Thanks to these observations, the dynamics of ocean carbon, oxygen, nutrients, primary producers, pH and bio-optical properties can be examined in all three spatial dimensions. The increased availability of these observations allows us to unravel biogeochemical processes, and validate and test hypotheses across a range of spatial and temporal scales. These new observations will also substantially improve the quality of biogeochemical models by allowing vigorous validation, improved parameterizations and formal data assimilation.

In this session, we welcome contributions leveraging the high data availability provided by BGC-Argo floats combined with theoretical or numerical models, data assimilation, machine learning, multi-platform sensors or other novel interpretative methodologies that expand the surface view of ocean ecosystem dynamics into the vertical dimension.
