Ocean Eddy Identification and Tracking using Neural Networks

, 2018
Global climate change plays an essential role in our daily life. Mesoscale ocean eddies have a significant impact on global warming, since they affect the ocean dynamics, the energy as well as the mass transports of ocean circulation.
