Instability and Diapycnal Momentum Transport in a Double-Diffusive, Stratified Shear Layer

Creator:

Smyth, William D. and Kimura, Satoshi

Abstract:

The linear stability of a double-diffusively stratified, inflectional shear flow is investigated. Double-diffusive stratification has little effect on shear instability except when the density ratio R[subscript]ρ is close to unity. Double-diffusive instabilities have significant growth rates and can represent the fastest-growing mode even in the presence of inflectionally unstable shear...

Modeling the detection range of fish by echolocating bottlenose dolphins and harbor porpoises

Creator:

Au, Whitlow W. L., Benoit-Bird, Kelly J., and Kastelein, Ronald A.

Abstract:

The target strength as a function of aspect angle were measured for four species of fish using dolphin-like and porpoise-like echolocation signals. The polar diagram of target strength values measured from an energy flux density perspective showed considerably less fluctuation with azimuth than would a pure tone pulse. Using detection...
