Quantifying linear disturbance growth in periodic and aperiodic systems

Creator:: Wolfe, Christopher Lee
Abstract:: The mathematical and physical connections between three different ways of quantifying linear predictability in geophysical fluid systems are studied in a series of analytical and numerical models. Normal modes, as they are traditionally formulated in the instabilities theories of geophysical fluid dynamics, characterize the asymptotic development of disturbances to stationary...

Mathematical approaches to the physics of mesoscale oceanography

Creator:: Early, Jeffrey J.
Abstract:: The long-term evolution of Gaussian eddies is studied in an equivalent barotropic model using both linear and nonlinear quasi-geostrophic theory in an attempt to understand westward propagating satellite altimetry tracked mesoscale eddies. By examining both individual eddies and a large basin seeded with eddies, it is shown that long term...

Establishing suitability of an ocean model for a poleward undercurrent study

Creator:: Duran, Rodrigo
Abstract:: Modifications of an ocean model are described, as the objective for which the model was used changed to study the kinematics and dynamics of an eastern-boundary poleward undercurrent.

Deformation in the Peru Trench, 6⁰-10⁰S

Creator:: Prince, Roger Allan
Abstract:: Detailed surveys of several segments of the Peru Trench show that the region between 6° to 10⁰ S is an area of recent deformation. Seismic reflection records across the axis of the trench show faulting, uplift, and tilting of the sedimentary fill and the acoustic basement. Uplift of the acoustic...

Long baroclinic planetary waves in a nonzonal vertically sheared mean flow

Creator:: Cerovecki, Ivana
Abstract:: We consider long planetary waves of annual period linearized about a steady, wind-driven subtropical (ST) gyre circulation. The circulation divides the gyre into an eastern zone (EZ) where only the surface layer is in steady motion and a western zone (WZ) where both the surface and the middle layer are...

The cross-equatorial structure of tropical instability waves in sea surface height

Creator:: Lyman, John M.
Abstract:: A linearized model with two vertical modes has been developed to understand observed characteristics of monthly variability in the Equatorial Pacific from TOPEX/POSEIDON measurements of Sea Surface Height (SSH). The 2-mode model is obtained from an equatorial beta plane model that has been linearized about a geostrophically balanced mean flow...

Field validation of a nearshore circulation model for alongshore-nonuniform flows

Creator:: Wilson, Gregory W.
Abstract:: We investigate, theoretically and experimentally, the problem of modeling depth-integrated (2DH) surf zone circulation on an alongshore-nonuniform natural beach, with waves approaching from an arbitrary angle. An approximate theoretical model is developed, which captures the important effect of advection in the alongshore dynamics, and shows that a nondimensional parameter Re[subscript]s...

Relationships between oceanographic factors and the distribution of juvenile coho salmon (Oncorhynchus kisutch) off Oregon and Washington, 1982-1983

Creator:: Chung, Alton W.
Abstract:: Juvenile coho salmon (101-400 mm) were sampled by purse seine off the Pacific Coast from Waatch Point, Washington to Four Mile Creek, Oregon, out to 30 mi offshore, during the months of May, June, and September in 1982 and 1983. Sea surface temperature, surface salinity, surface chlorophyll-a concentration, and Secchi...

The effects of thermodynamic parameterizations, ice shelf geometry, and tides on modeled basal melting of Weddell Sea ice shelves

Creator:: Mueller, Rachael D.
Abstract:: Antarctic Ice Sheet mass balance and, hence, sea level change is affected by the floating extensions of outlet glaciers and ice streams that take up about 44% of the coastline (Drewry et al., 1982) and are referred to as "ice shelves". Ice sheet mass loss accelerates when these ice shelves...
