Structure and seismic hazards of the offshore Cascadia forearc and evolution of the Neogene forearc basin

Creator:: McNeill, Lisa C.
Abstract:: The Cascadia subduction zone has been characterized as a typical Chilean-type subduction zone based on qualitative comparisons of plate age and convergence rate, with simple forearc structure. However, the discovery of unusual structural styles of deformation, variations in the morphology of the forearc, and its absence of seismic activity suggest...

Acoustic monitoring of earthquakes along the Blanco Transform Fault Zone and Gorda plate and their tectonic implications

Creator:: Dziak, Robert P.
Abstract:: Hydroacoustic tertiary (T-) waves are seismically generated acoustic waves that propagate over great distances in the ocean sound channel with little loss in signal strength. Hydrophone recorded T-waves can provide a lower earthquake detection threshold and an improved epicenter location accuracy for oceanic earthquakes than land-based seismic networks. Thus detection...

Crustal structure and seismicity of the Gorda Ridge

Creator:: Solano-Borrego, Ariel E.
Abstract:: We have determined the seismic crustal structure of the northern part of the Gorda Ridge using signals generated by explosive charges and recorded on Ocean Bottom Seismometers. The shot pattern forms two parallel lines, one on the east flank and the other along the median valley. Inversion of the travel...

Anthropogenic activities associated with the status of salmon stocks in Pacific Northwest watersheds

Creator:: Mrakovcich, Karina Lorenz
Abstract:: Stocks of salmon are declining in the Pacific Northwest. Based on region-wide studies that list and categorize the status of salmon stocks (Nehlsen et al., 1991; Huntington et al., 1994; and Nawa, 1995), I analyze the watersheds where stocks of salmon spawn for several anthropogenic variables, most of which are...

From the forest to the sea : a story of fallen trees

Creator:: Maser, Chris, Tarrant, Robert F., Trappe, James M., and Franklin, Jerry F.
Abstract:: Large fallen trees in various stages of decay contribute much-needed diversity of ecological processes to terrestrial, aquatic, estuarine, coastal beach, and open ocean habitats in the Pacific Northwest. Intensive utilization and management can deprive these habitats of large fallen trees. The publication presents sound information for managers making resource management...
