In this thesis anomalous downcore shallowing of paleomagnetic
inclinations is interpreted to be caused by sediment compaction. Thus,
compaction-induced inclination shallowing may influence tectonic
reconstructions that are based on inclinations...

A 3D seismic volume was acquired summer 2000 over the southern end of
Hydrate Ridge (FIR), an anomalously shallow ridge 100 km offshore Newport,
Oregon. The survey followed a succession of scientific expeditions aimed at
studying the gas hydrates...

During the 2008 and 2009 breeding seasons of murres Uria spp., we combined visual observations of these predators with active acoustics (sonar), fish trawls, zooplankton net tows, and hydrographic measurements in the area surrounding breeding...

A structure map was constructed of the continental shelf between
Cape Blanco and Coos Bay, Oregon, exclusively from an interpretation
of approximately 700 km of continuous seismic profiles.
At least ten discernible seismic units were mapped on the...

Pesticides are widely used to control undesirable pests and may be applied directly to water or lands directly adjacent to water. There can be unintended consequences, however, to native, threatened, and endangered species. There is little...

A diagnostic modeling study of the cloud and precipitation
processes, and also frontogenesis have been analyzed in a severe
narrow cold-frontal rainband with the aid of a three-dimensional,
diagnostic cloud model.
The results of the model...

Steady, longitudinally invariant, barotropic, boundary layer flow is numerically studied at low latitudes where advective accelerations may he large and the Coriolis parameter is small. Flow is generated by specifying the pressure gradient field...

The steady Reynolds stress and turbulent energy equations for steady, horizontally homogeneous mean flow are used to relate the Reynolds stress u′w′ to the mean wind shear and heat fluxes in the planetary boundary layer.
The resulting Reynolds...

The response of vertically averaged boundary layer flow to specified time-dependent pressure gradients is examined. The adjustment rate of the boundary layer flow to the pressure gradient field is found to be proportional to the strength of the...

The influence of boundary layer pumping on an externally forced, synoptic-scale flow is examined. The results follow earlier theories of stratified incompressible Boussinesq flow theories in that the spin-down time scale and the penetration depth...

Even slight terrain inhomogeneities can cause large horizontal variations in the clear, stably stratified, nocturnal boundary layer largely through cold air drainage. By early morning the valleys and depressions can be several degrees cooler than...

An analytical two-layer approximation of atmospheric flow is developed to study boundary-layer production of vertical motion. The model consists of a boundary layer topped by a free-flow layer. Both layers am time-dependent and possess different...

The two main approaches presently in use for studying the boundary layer are quite dichotomous. It is shown that the Ekman approach which uses an eddy coefficient fixed in height can load to a serious contradiction this approach should be avoided...

Aircraft data collected at the top of a cloud-topped mixed layer during the Air Mass Transformation Experiment are analyzed. Entrainment instability due to evaporation of liquid water is found to occur intermittently. This instability and upward...

Nocturnal boundary-layer data from the Wangara and Voves experiments are analyzed. The lower part of the nocturnal inversion layer normally appears to be turbulent but strongly stratified. The upper thicker part of the inversion layer is...

A unified scale analysis of the momentum balance of downslope gravity flows is developed to organize previous theories for the case of negligible ambient flow and fixed temperature deficit scale. The values of several nondimensional parameters are...

The structure of turbulence and transport of heat is examined from data obtained from 11 aircraft soundings executed in heated boundary layers during the Air Mass Transformation Experiment. Various influences on the turbulent transport are...

The structure of turbulence in a strongly stratified nocturnal boundary layer is studied using fast-response aircraft data collected under clear sky conditions with weak ambient flow. The principal source of turbulence is shear generation near the...

The approximate equations for shallow motions are derived mainly by following the approach of Spiegel and Veronis and the subsequent development of Dutton and Fichtl. Other derivations are also briefly noted. While each derivation assumes shallow...
