SCOR Working Group 168 Webinar #10

 Title: Neural-BGC: Neural Network emulation of BGC from T/S data for interpolation and coupled Physics-BGC simulations

 Presenter:

Said Ouala

IMT Atlantique

 

Ocean biogeochemistry (BGC) regulates key variables such as oxygen and nutrients that are essential for marine ecosystems and the global carbon cycle. However, BGC observations remain sparse, and BGC models rely on poorly constrained parameters and processes. To address these limitations, we developed Neural-BGC, an AI model trained on millions of ocean observations collected since 1965. Neural-BGC emulates BGC variables from temperature and salinity fields. It is used both for interpolation and coupled physics-BGC simulations. For interpolation, the model estimates BGC variables from available temperature and salinity observations, and these estimates are combined with direct oxygen measurements through optimal interpolation to produce gridded products. When coupled to a physical ocean model, Neural-BGC reproduces  biogeochemical features, including the oxygen minimum zones of the Indian Ocean and nutrient-rich blooms in the Canary Current Upwelling System.
