Plate boundaries are commonly regions of complex, diffuse deformation with
the motion across the boundary accommodated by numerous structural systems, rather
than being narrow, discrete zones of deformation. One such boundary occurs where
the North American plate makes contact with Juan de Fuca, Gorda, and Pacific plates
along the west...
Northeast Pacific Ocean sediments were analyzed to determine the past
relationship between northeast Pacific sea surface conditions and the climate on the
adjacent continent, the Pacific Northwest of North America. Studies of modern
ocean-atmosphere interactions demonstrate the significant effect sea surface conditions
and atmospheric circulation in the Northeast Pacific Ocean...
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 from deep-sea sediment
Progressive downcore shallowing of the remanent inclination was
observed in a 120-m section of Plio- Pleistocene...
Using a linear quasi-geostrophic model of large scale spiraling flow and vertical density
gradient in the eastern North Pacific, we evaluate the complex dispersion relationships
for quasi-geostrophic waves. Our calculations indicate that the geostrophic circulation
of the eastern North Pacific can locally convert potential energy to mesoscale
kinetic energy on...
