Seismic ray trace techniques applied to the determination of crustal structures across the Peru continental margin and Nazca plate at 9 ̊S. latitude

Creator:: Jones, Paul Roy III
Abstract:: Seismic refraction, reflection and gravity data obtained across the Peru continental margin and Nazca Plate at 9° S. permit a detailed determination of crustal structure. Complex structures normal to the profile require the development of a ray trace technique to analyze first and later arrivals for eleven overlapping refraction lines....

Habitat quality and biotic integrity in mountain streams of East Maui, Hawaii

Creator:: Carter, H. Jamieson
Abstract:: Hawaiian streams are valued for environmental, cultural, and aesthetic qualities. Windward streams in East Maui, Hawaii are diverted to irrigate crops in central portions of the island. Diversions typically remove 100% of the base flow and leave downstream reaches dry most of the year. Ground water seeps and springs contribute...

Predicting Watershed Characteristics Using Bacterial DNA

Creator:: Chadwick, Jessica A.
Abstract:: This study was conducted to determine if bacterial DNA present streams could be used to predict upstream watershed characteristics. Previous studies have found that bacterial composition in soil is influenced by land use. It was hypothesized that if the bacteria present in a stream is known that it can be...

Effects of Forest Harvest, Floods, and Wildfire on Bedload Export from Headwater Catchments in the H.J. Andrews Experimental Forest, 1957 – 2022

Creator:: Wright, Charles M.
Abstract:: This study examined how annual bedload export volume and bedload characteristics were related to disturbances including logging, floods, debris slides, and wildfires over 48 to 65-year periods in small, steep catchments in conifer forests of the western Cascade Range, Oregon. Bedload – the material rolling, sliding, or saltating along the...

Microearthquake studies of the Blanco fracture zone and Gorda Ridge using Sonobuoy arrays

Creator:: Jones, Paul Roy III
Abstract:: University deployed two arrays of three sonobuoys over the Blanco fracture zone and two arrays of four sonobuoys over the Gorda ridge to detect and locate microearthquakes. Microearthquake activity predicted by plate tectonic theory for the Blanco fracture zone and Gorda ridge was observed by these arrays to originate from...

Opening Pandora’s Box: Machine learning applications for chemical forensics and non-target chemical analyses

Creator:: Davila-Santiago, Emmanuel
Abstract:: Water bodies act as chemical data loggers that contain tens of thousands of molecules that represent the sum of the biological, chemical, and physical processes occurring within a watershed. We hypothesize that unique chemical signatures present within a water sample can be informative of upstream processes. By extracting non-polar organic...

Road networks, timber harvest, and the spread of Phytophthora root rot infestations of Port-Orford-cedar in southwest Oregon

Creator:: Clark, William C.
Abstract:: Phytophthora lateralis is the causal agent of cedar root rot, a fatal forest pathogen whose principal host is Chamaecyparis lawsoniana (Port-Orford-cedar), a predominantly riparian-restricted endemic tree species of ecological, economical, and cultural importance to coastal Oregon and California. Local scale distribution of P. lateralis is thought to be associated with...
