Wave scattering by undulating bed topography in a two-layer ocean
two-layer ocean wave scattering bottom undulations reflection transmission coefficients
2011/9/13
The problem of wave scattering by undulating bed topography in a two-layer ocean is investigated on the basis of linear theory. In a two-layer fluid with the upper layer having a free surface, there e...
Spectral variations of light scattering by marine particles in coastal waters, from visible to near infrared
coastal waters light scattering marine particles
2014/4/18
Field measurements and Mie calculations of the particulate light-scattering coefficient (bp, in m21
) in the nearinfrared and visible spectral domains are combined to quantify and model the effect of...
Characterizations of minerogenic particles in support of modeling light scattering in Lake Superior through a two-component approach
minerogenic particles modeling light scattering
2014/4/18
The role of suspended minerogenic particles in light scattering in eastern Lake Superior and Keweenaw Bay (11
sites) during July of 2006 was evaluated with an individual particle analysis technique (...
The Scattering of Rossby Waves by a Semi-Infinite Barrier
Rossby Waves Semi-Infinite Barrier
2009/4/3
We discuss the scattering of divergent Rossby waves by a semi-infinite vertical barrier of arbitrary orientation on a β plane. The Wiener-Hopf method is used to obtain an integral representation of th...
The Scattering of Continental Shelf Waves by an Isolated Topographic Irregularity
Continental Shelf Waves Isolated Topographic Irregularity
2009/2/13
A model for the scattering of a continental shelf wave by a small, isolated and smooth topographic irregularity is developed. It is found that a wave of frequency ω, incident on a bump of a sufficient...
A Formal Theory of Internal Wave Scattering with Applications to Ocean Fronts
Internal Wave Scattering Ocean Fronts
2009/2/10
A concise theory for scattering of internal waves at localized inhomogeneities (i.e., topographic features, baroclinicity in the density field, variations of the mean sea level, jetlike currents) in t...
Scattering of Sound by Internal Wave Currents：The Relation to Vertical Momentum Flux
Internal Wave Currents Vertical Momentum Flux
2009/2/9
Internal waves scatter sound by two related perturbations: 1) those associated with vertical particle displacements (x, y, z, t) in the presence of a vertical gradient of (potential) sound speed (δc =...
The Scattering of a Continental Shelf Wave by a Long Thin Barrier Lying Parallel to the Coast
Continental Shelf Wave incident shelf wave
2009/1/15
The scattering of an incident shelf wave by a long thin offshore barrier located parallel to the coast is solved for a general monotonically increasing depth profile, using the unforced, inviscid baro...
Recent observations suggest that the space-time spectrum of near-inertial motions is strongly modulated by ocean fronts and geostrophic shear. This paper postulates a mechanism that may be responsible...
Scattering of Coastally Trapped Waves by Changes in Continental Shelf Width
Coastally Trapped Waves Continental Shelf Width
2009/1/7
The scattering of dispersive, barotropic, coastally-trapped waves by narrowing and widening shelves is investigated. The shelves considered maintain a shelf-similar exponential shape. For such shelves...
Scattering of Continental Shelf Waves at a Discontinuity in Shelf Width
Continental Shelf Waves Shelf Width Scattering
2009/1/7
An analytical solution is presented for the scattering of a free shelf wave incident upon a discontinuity in shelf width in a barotropic ocean. The discussion of solutions relying on backscattered fre...
Topographic Scattering of Equatorial Kelvin Waves
Topographic Scattering Equatorial Kelvin Waves
2009/1/6
We develop a linear, reduced-gravity model with two active layers above a deep, resting layer to examine the scattering of equatorial Kelvin waves from meridional submarine ridges. Model ridges, ideal...
Radar Returns from the Sea Surface—Bragg Scattering and Breaking Waves
Radar Returns Breaking Waves Sea Surface—Bragg Scattering
2009/1/6
Recent ideas on the structure of the equilibrium range of wind-generated ocean waves are applied to the question of radar backscattered returns from the sea surface. It is shown that the backscatterin...

Shelf Wave Scattering Longshore Jump Topography
2009/1/5
The scattering of barotropic shelf waves by an abrupt jump in longshore topography is examined for unbounded and bounded exponential shelves by matching modal representations for longshore transport a...
Scattering of Inertial Waves by Rough Bathymetry
Inertial Waves Rough Bathymetry Scattering
2009/1/5
Interactions between near-inertial waves and rough bathymetry are studied theoretically and numerically. Rough bathymetric features cause scattering, even when their length scales are much smaller tha...
