Mapping surficial geologic habitats of the Oregon continental margin using integrated interpretive GIS techniques

Creator:: Romsos, Christopher G.
Abstract:: We map the regional physiography and surficial lithology (Surficial Geologic Habitat or SGH) over the continental margin of Oregon. This thesis develops, describes, and implements an iterative interpretive method to map seafloor habitat types from disparate geological and geophysical datasets including: bathymetric images, sidescan sonar images, seismic reflection profiles, sediment...

Crustal structure of the Continental Borderland and the adjacent portion of Baja California between latitudes 30⁰N and 33⁰N

Creator:: Plawman, Thomas Leon
Abstract:: Gravity, magnetic and seismic data indicate that the oceanic crust is 9.7 km thick west of the Continental Borderland. The top of the mantle is about 12 km deep under the Borderland, and deepens to 27 km beneath the Peninsular Ranges of Baja California. The mantle is about 20 km...

Gravity and structure of the Pacific continental margin of Central Mexico

Creator:: Sanchez Zamora, Osvaldo
Abstract:: Data collected by personnel of the Geophysics Group at Oregon State University and the Instituto Oceanografico of the Direccion General dé Oceanografia are used to construct a free-air anomaly map for the central part of the Pacific continental margin of Mexico, which shows the gravity expression of major structural features...

Frequency response function analysis of the equatorial margin of Brazil using gravity and bathymetry

Creator:: Macario, Ana L. G.
Abstract:: The overall objective of this study is to address questions concerning the long-term mechanical strength of the lithosphere across the equatorial margin of Brazil. The approach used in this study consists of calculating the frequency response function estimates, also called admittance, using gravity and bathymetry data. These experimental estimates are...

Crustal structure of the northwestern continental margin of the Indian subcontinent from gravity and magnetic data

Creator:: Soofi, Muhammad Asif
Abstract:: The continental margin off the coast of Pakistan between the Murray ridge and the Gulf of Cambay has been studied in this work using gravity, magnetic and bathymetric data. Two dimensional gravity and magnetic models based on free-air gravity and residual magnetic data are developed along a north-south profile off...

Wide-angle seismic refraction and reflection studies of the northern California and southern Oregon continental margins

Creator:: Keser, Judith
Abstract:: Recently obtained airgun-sonobuoy wide-angle refraction and reflection profiles provide data to study crustal velocities and structures along the continental margin of northern California and Southern Oregon. In the thick sedimentary wedge at the base of the continental slope, as many as five distinct layers can be seismically observed, which range...

Mapping semi-regular autonomous underwater vehicle glider observations onto a cross-shelf section

Creator:: Peery, Andrew Tristan
Abstract:: Two Autonomous Underwater Vehicle Gliders have alternated continuous sampling of a 45-nautical mile transect line (the Newport Hydrographic Line) across the Oregon continental shelf since April, 2006. Strong currents (>25cm/s) push the gliders off their trajectories as they survey this transect line, preventing them from sampling the historically occupied stations...
