This work is a study on the profile Munk and the bi-exponential profile for the speed of sound at sea, where it made a generalization. Profile Munk studied two disturbances, a dependent of another re distance of z depth. By varying the parameters in numerical simulations we obtain the phase space, where we can observe the properties of the idealized model, which has chaos regions, islands and resonance logs that are invariant features of integrable almost systems. To propose a biexponential profile exponent quadratic replacement by an exponent k that consists of a generalization for the idealized model. By varying the values for the parameter k, we simulate the cooling or heating and the ocean waters. Using the space of phases we can analyze the system properties
