Modelling the deep ocean at high resolution
Numerical modelling is a key tool for understanding deep ocean dynamics, where observations remain sparse, particularly at submesoscales (1–30 km). Jonathan Gula, from the Laboratoire d’Océanographie Physique et Spatiale, Université de Bretagne Occidentale, uses high-resolution basin-scale and regional simulations to investigate how interactions between currents, topography, and mixing shape abyssal circulation and tracer transport.
