Scattering from Inhomogeneitiestheoretical and experimental descriptions concentrate on the smaller scatterers, especially fish, since internal waves and other wave motions will be covered else-where. A great variety of effects is listed, together with their significance for the scatterers themselves and for the resulting sonar limitations.

A Calculation of Complex Wavenumbers of Virtual Modes in a Pekeris Modelequency (100Hz) in a Pekeris model. The propagation loss of the virtual modes in water is calculated by using the imaginary part of the wavenumbers. This result is compared with the propagation loss evaluated by the method of C.T. Tindle.

Da die Verh?ltnisse klein und leicht übersehbar sind, ist zu erwarten, dass die Bewohner der von einer Kleinbahn durchzogenen Gegend auch auf die Betriebsführung einen Einfluss zu üben versuchen werden, und, da hier viel
