Deep learning model predicts ocean currents for plastic debris cleanup

Researchers have developed Drift Field Net (DFN), a deep neural network designed to predict ocean surface flow fields using satellite observations. This model aims to improve forecasts of particle drift, crucial for strategies targeting plastic debris accumulation in areas like the North Pacific Subtropical Gyre. DFN utilizes a two-stage training process, combining simulated data pretraining with Lagrangian fine-tuning using an advection-consistent loss function. In evaluations, DFN demonstrated a 20 km reduction in mean positioning error after a 7-day forecast compared to an operational physics-based system, with further improvements achieved through Lagrangian fine-tuning.
