Water chemistry of Oregon Cascade wilderness lakes : a comparison to 1985 data

Creator:: Logan, Michael Burke
Abstract:: The Western Lake Survey (WLS) of 1985 documented the status of lake water chemistry across the western US and inferred population representations of various subregions and geomorphic units via statistically analyses. Results from this 1985 study indicated that lakes of the Oregon Cascades had the second most pristine and dilute...

Full-Scale Experimental Investigation of the Seismic Capacity of Reinforced Concrete Column-Footing Specimens Retrofitted with Titanium Alloy Bars Considering Effects of Soil-Structure Interaction on Vintage and Retrofitted Column-Footing Specimens

Creator:: McGinn, Logan
Abstract:: Reinforced concrete (RC) column-footing substructures are widely used to support bridges along critical transportation corridors in Oregon. Those built prior to 1971 were typically designed to resist only gravity loads. Therefore, they are vulnerable to damage or collapse during strong ground shaking. To prevent collapse, seismic retrofits have been developed...

Forest Response to Water Availability and Disturbance in the Western United States

Creator:: Berner, Logan T.
Abstract:: Earth’s atmosphere is unequivocally warming due to CO₂ and other greenhouse gas (GHG) emissions from human activities and this is having widespread impacts on forest ecosystems that provide important services to human societies. Forest ecosystems help regulate atmospheric CO2 concentrations by sequestering carbon in tree biomass and soils, which is...

Nanomechanical Characterization of Atomic Layer Deposition Coatings for Biomedical Applications

Creator:: Bauer, Nicole Lea
Abstract:: Atomic Layer Deposition (ALD) is a promising technique for the production of biologically safe, wear resistant and corrosion protective coatings for orthopedic applications. In this work, the impact of coating thickness and surface preparation on the hardness (H), elastic modulus (E), wear resistance, and delamination of ALD Al2O3 films is...

Functional analysis of flight crew performance : a systems engineering perspective on crew resource management

Creator:: Sukhia, Cherag R.
Abstract:: Many failures of interpersonal communication and coordination in the aircraft cockpit have been found to occur as a result of poor management of flightdeck 'resources'. Crew Resource Management (CRM) is a concept that has evolved within the aviation community to specifically address this issue of resource management. The concept of...

Creator:: Mitchell, Logan E., Buizert, Christo, Brook, Edward J., Rhodes, Rachael H., and et al.
Abstract:: Interpretation of ice core trace gas records depends on an accurate understanding of the processes that smooth the atmospheric signal in the firn. Much work has been done to understand the processes affecting air transport in the open pores of the firn, but a paucity of data from air trapped...

Multidecadal variability of atmospheric methane, 1000–1800 C.E.

Creator:: Mitchell, Logan E., Brook, Edward J., Sowers, Todd, McConnell, J. R., and Taylor, Kendrick
Abstract:: We present a new high-precision, high-resolution record of atmospheric methane from the West Antarctic Ice Sheet (WAIS) Divide ice core covering 1000–1800 C.E., a time period known as the late preindustrial Holocene (LPIH). The results are consistent with previous measurements from the Law Dome ice core, the only other high-resolution...

Creator:: Mitchell, Logan, Brook, Edward J., Lee, James E., Buizert, Christo, and Sowers, Todd
Abstract:: The origin of the late pre-industrial Holocene (LPIH) increase in atmospheric methane concentrations has been much debated. Hypotheses invoking changes in solely anthropogenic sources or solely natural sources have been proposed to explain the increase in concentrations. Here two high-resolution, high-precision ice core methane concentration records from Greenland and Antarctica...
