Volcanology and petrology of the Rattlesnake Ash-Flow Tuff, eastern Oregon

Creator:: Streck, Martin J.
Abstract:: The Rattlesnake Ash-Flow Tuff erupted 7.05±0.01 Ma from the western Harney Basin, southeastern Oregon. The location of the vent area is inferred based on vent-ward increases in size of pumices, in degree of welding, and in degree of post-emplacement crystallization. Today's outcrops cover 9000 km2 and estimated original outcrop coverage...

Videographic and GPS techniques for monitoring active glacial surge: Bering Glacier, Alaska

Creator:: Thatcher, P. Anthony
Abstract:: Aerial videography in combination with GPS were used to monitor the active surge of Alaska's Bering Glacier. The large aerial extent of the study area and the unpredictable weather in coastal Alaska required innovative techniques to be used in order to successfully monitor the surge environment. A portable aerial videographic...

Vegetation classification of wild turkey habitat in Umpqua National Forest using color aerial photography

Creator:: Hazell, Bret Jack
Abstract:: This project focuses on the classification of vegetation as a habitat for wild turkeys. The vegetation classification discussed here is only one part of a study looking at habitat requirements, seasonal use patterns, and brood-rearing habits of wild turkeys in Southern Oregon. The vegetation classification was performed for an area...

Using a single-well push-pull test to estimate mass transfer rate parameters

Creator:: Kelley, Michael John
Abstract:: More efficient methods are needed for the in-situ evaluation of mass transfer parameters which describe the movement of solutes through aquifer material. The objective of this study was to develop a method for estimating diffusion rate and capacity coefficients using a single-well, "push-pull" tracer test. The method consists of the...

User fees: issues and policy on Washington state public lands

Creator:: Caudill, David S.
Abstract:: Outdoor recreational activities on public lands have increased dramatically in the past few decades. Americans are logging millions of recreational visitor days (RVD's) participating in activities such as hiking, biking, wildlife viewing, photography and many others. This increased participation though is having detrimental effects on these lands and the agencies...

Use of GIS to determine effectiveness of natural attenuation

Creator:: Sharma, Ritu
Abstract:: Louisiana Army Ammunition Plant (LAAP), located near Shreveport, Louisiana, is a government-owned contractor-operated plant. Its purpose is to manufacture, load and assemble ammunition items. Area P has been used over the past 40 years to dump explosive-laden wastewater into 16 unlined lagoons. In 1989 LAAP was placed on the National...

Transfers of water rights in New Mexico's Rio Grande basin : spatiotemporal and sociocultural patterns

Creator:: Shively, David D.
Abstract:: Water right marketing and transfers represent a resource reallocation strategy that has received considerable attention in the American West owing to nearly full appropriation of water in the region. Several western states permit transfers between different uses and places of use thus allowing water to move to higher-value economic activities....

Trace element distribution in igneous minerals and liquids

Creator:: Forsythe, Lance M.
Resource Type:: Dissertation

Tourism and community perceptions : an examination of Mount St. Helens' tourism as perceived by local residents

Creator:: Baker, Randal G.
Abstract:: Since the eruption of Mount St. Helens on May 18,1980, the rural communities within its shadow have experienced tremendous change. Tourism has become a highly visible and somewhat controversial component of change in the region, and its importance to local economies has increased. As a result of increased tourism development...

Three-dimensional gravity analysis of the Pacific-Antarctic east Pacific rise at 36.5°S, 49.8°S and 54.2°S

Creator:: Enriquez, Kelly D.
Abstract:: Three-dimensional gravity analysis is the process of removing the predictable components from the free-air gravity anomalies and has proven to be useful for interpreting the subsurface structures and active processes at mid-ocean ridges. The three-dimensional effects of the seafloor and Moho topography, assuming a constant crustal thickness and constant crust...
