Methane reservoirs and seeps are an active component
of the continental margin carbon budget and represent a
poorly characterized pathway for reduced carbon cycling
and methane input to the atmosphere. Active gas seeps from
three shelf settings on the Cascadia Continental Margin off
Oregon and Northern California contain nearly pure...
The infrared absorption spectrum from 3200 cm⁻¹ to 4025
cm⁻¹ of thin crystals of ⁶LiOH (99%⁶Li.) is presented and compared
to the spectrum of [superscript]NLiOH (93%⁷Li). A shift in only one of the band
pairs supports the lattice combinations model and assists in making
assignments for the major features of...
This report presents hydrographic and chemical data from the eastern
tropical North Pacific Ocean collected in January 1977 aboard Oregon State
University's (OSU) R/V WECOMA during Leg I of Cruise WELOC 77. The purpose of
the cruise, WELOC-77-I, was to investigate the distributions of dissolved nitrous
oxide and molecular hydrogen'...
Axial Seamount is an active submarine volcano located at the intersection between the Cobb hotspot and the Juan de Fuca spreading centre in the northeast Pacific Ocean1, 2. The volcano has been closely monitored since it erupted in 1998 (refs 3, 4). Since then, Axial Seamount seemed to exhibit a...
Material testing experiments are needed to enable the next generation of nuclear fission reactors. Concluding in 2009, the Boosted Fast Flux Loop (BFFL) project was devised as a way to test fast reactor materials and fuels in the Advanced Test Reactor (ATR), however the experiment location it used is now...
Nuclear fuel management is an optimization problem on many levels. Finding “viable” solutions for the core reload design problem is difficult without expert knowledge and software automation. Small modular reactors with a shared used fuel pool demonstrate a novel opportunity for fuel cycle optimization.
A Python package was developed and...
The objective of this study was to provide first order observations of bed level changes occurring in streambed simulated culverts throughout an annual period. To accomplish this, 30 culvert sites were selected in Oregon and Washington, and monitored over, at least, a 2 year period. Streambed scour and redeposition data...

Many miles of roads are built in the Pacific Northwest Forests to provide access for logging and fire protection. Logging roads often cross steep mountainous terrain. Logging roads and the associated cut and fill slopes represent a discontinuity in the natural stress state in the soil mantle. These conditions result...
