Abstract :
A VHF radar has been used to locate a drifting transponder for measuring the lagrangian circulation in the coastal zone. It is expected that simultaneous use of several drifters will give an insight into small scale dispersion and diffusion phenomena. The paper describes the radar and transponder system, and outlines the method used to estimate the horizontal diffusion coefficient
