Short summary
Most long-term satellite-based global current datasets capture only large-scale flows driven by pressure differences, missing important nonlinear motions. We used satellite data and a physics-informed deep learning method to create a new global dataset, including these previously missing components. Our currents are more accurate than traditional products, and we show that motions driven by nonlinear effects strongly influence the transport of heat, carbon, and nutrients in ocean.
