Overview  \nRecent advances in machine learning present new ways for geoscientists to predict geological subsurface properties. Fourier Neural Operators (FNOs) [3] are increasingly being used as an alternative to conventional seismic imaging approaches [7] . FNOs have been shown to predict accurate simulations of seismic waves several hundred times faster than physics-based solvers post-training [2] . In synthetic volcanic settings, FNOs have been applied successfully to both the forward and inverse problem, capturing fine-scale velocity structure in heterogeneous models and seismograms [5] . However, transferring the successful performance of simulation-trained FNOs to field-gathered seismic data is yet to be attained. To achieve this, training models must contain representative small-scale velocity heterogeneities and topography to produce highly scattered codas in synthetic seismograms.  \nThis research presents work in progress on simulation-to-real FNO applications using field-gathered seismic data from offshore sedimentary basin settings as a testbed environment. Historical seismic survey datasets from Atlantic sedimentary basins are often accompanied by additional site-specific geological constraints. This makes the creation of synthetic velocity models and seismograms with field-derived properties possible, centering the collation of data for real-world machine learning applications in the numerical domain.  \nThe longterm research goal is to bring insights gained from training FNOson a better understood seismic environment to volcanic and other complex environments in future work.  \n\n|  |  |\n| --- | --- |\n| \u003Cbr>\u003Cbr>2.
