The solution to the logistic equation is an S-shaped curve determined by r, the intrinsic rate of increase, and [K.sub.1], the carrying capacity (the subscript 1 is used to distinguish carrying capacity, [K.sub.1], from K, the eddy-diffusion coefficient).
K = eddy-diffusion coefficient = 10 [m.sup.2] [s.sup.-1];
The eddy-diffusion coefficient, K, is an approximation of the average dispersion rate of passive particles in the ocean.
