Mass Transport by Second Mode Internal Solitary Waves
2013
Abstract : The overall scientific objective of the proposed effort is to improve our understanding of the propagation and mass transport of internal solitary waves (ISW), particularly mode-2 ISW, and their significance for coastal ocean processes. In recent years numerous observations of mode-2 ISW have been reported so that it appears that such waveforms may be more prevalent than previously thought. Large amplitude mode-2 solitary waves have unique properties, in particular they encompass regions of internal recirculation that enable mass transport over large distances. Transport of mass along a pycnocline can affect upper ocean mixing and distribution of biological and chemical constituents. Moreover, coherent ISW packets can have significant effects on the propagation and scattering of acoustic signals.
