you have been put in charge of tracer test to determine the oceanic diffusion coefficient diffusion coefficient 8 km offshore of doha beach. 10 kg of a tracer were released into the top 3 m of ocean at coordinates x=0m, by=0m, and the distribution of tracer concentration (in mg/l) sampled by fishermen 1 hour after release. use the sample concentration to estimate the components of the diffusion coefficient and the mean ocean current. of what practical use are the diffusion coefficient you have just determine?
