Grigor’eva, N. S. The field of a point monochromatic sound source in the stratified ocean perturbed by a large scale flow. (Russian. English summary) Zbl 0615.76108 Zap. Nauchn. Semin. Leningr. Otd. Mat. Inst. Steklova 156, 49-60 (1986). For general system of hydrodynamic equations the method of normal modes in the case of a point sound source in stratified ocean perturbed by a current is advanced. The comparison with analogous results for the case of quasi-potential equation gives the possibility to estimate the effect of replacement of generalized equation of state by approximating the state equation.
