An investigation of the distribution and abundance of ichthyoplankton and juvenile benthic fishes in relation to nearshore hypoxia within the Northern California Current system

Creator:: Johnson, Angela M.
Abstract:: Nearshore hypoxia within the Northern California Current (NCC) system is a seasonal phenomenon caused by coastal upwelling and occurs mainly during late-summer and early fall. The effects of low oxygen levels on fish and invertebrate communities, particularly during early-life history stages, however, are poorly known for this area. I investigated...

Shear wave attenuation in unconsolidated laboratory sediments

Creator:: Brunson, Burlie A.
Abstract:: Shear wave attenuation measurements were made using ceramic bimorph transducers to excite transverse vibrations in a cylindrical column of unconsolidated sediment. Three different water-saturated sediments were used in an attempt to determine the effects of grain shape and sorting on the frequency dependence of attenuation. The mean grain size of...

Modeling of the Peru-Chile trench from wide-angle reflection profiles

Creator:: Goebel, Vaughn
Abstract:: A proposed modeling technique that yields a best fit to observed wide-angle reflection profiles incorporates (1) the use of migrated vertical reflection profiles to provide topographic control, (2) ray tracing to produce theoretical wide-angle reflection profiles for hypothetical crustal sections, and (3) the iterative adjustment of crustal layer dip, thickness...

Crustal structures and tectonism in southeastern Alaska and western British Columbia from seismic refraction, seismic reflection, gravity, magnetic, and microearthquake measurements

Creator:: Johnson, Stephen Hans
Abstract:: Seismic refraction measurements along two unreversed lines indicate that the earth's crust is 26 km thick in southeastern Alaska and 30 km thick along the Inside Passage of British Columbia. The crust in southeastern Alaska, north of Dixon Entrance, consists of a layer 9 km thick with a seismic velocity...

The dynamics of an isolated population of Acartia tonsa Dana (Copepoda) in Yaquina Bay, Oregon

Creator:: Johnson, John Kenneth
Abstract:: In the upper estuary of Yaquina Bay, Oregon, there is an annual population explosion of Acartia tonsa, (Dana) a calanoid copepod, during the months of July, August and September, followed by a rapid decline to virtual extinction in November. The restricted estuarine distribution affords an excellent opportunity to study the...

Deformation, fluid venting, and slope failure at an active margin gas hydrate province, Hydrate Ridge Cascadia accretionary wedge

Creator:: Johnson, Joel E.
Abstract:: During the last 15 years, numerous geophysical surveys and geological sampling and coring expeditions have helped to characterize the tectonic setting, subsurface stratigraphy, and gas hydrate occurrence and abundance within the region of the accretionary wedge surrounding Hydrate Ridge. Because of these investigations, Hydrate Ridge has developed as an international...
