Properties and extremes of geophysIcal nonlinear dispersive waves

Nonlinear dispersive wave groups or packets occur in a wide range of natural systems, exhibiting complex behaviors especially in focal zones where there is rapid wave energy concentration and possible wave breaking. In the presence of dispersion, pure plane waves of different wavelengths and directions traveling within a medium have different propagation velocities. Important classes of geophysical wave systems include surface gravity waves, oceanic and atmospheric internal waves, and seismic waves.

PAssive Monitoring with Ambient Seismic and Ocean Noise (PAMASON)

Ocean dynamics constantly generates seismic and acoustic noise (e.g. vie wave-seafloor interaction, surface wave activities, ice-noise and anthropogenic sources). This ubiquitous ambient noise waves, which can be measured continuously with hydrophones and seismic stations, travel around the earth and can be used to monitor their generating sources and image the propagating medium. This project will characterize the spatial and temporal generation mechanism of seismic and acoustic ocean noise sources which can be used for passive remote sensing and monitoring purposes.
