Short summary
A Lagrangian method is developed to track, document and analyze the origin and history of water masses in ocean features. Simulating synthetic tracers in the altimetry-derived velocity field, we identify and track the mesoscale eddies which have been sampled in the cruises after the Fukushima accident and estimate their risk of being contaminated by radionuclides. The simulated results are shown to be in a good qualitative correspondence with in situ measurements.
