The Toba Caldera Complex is the youngest resurgent caldera in the last 100 kyrs, formed from four overlapping eruptions starting 1.2 Myrs ago. The last caldera-forming eruption, the Youngest Toba Tuff eruption, occurred ~74 kyrs ago, emitting 2800 km3 of ash and pumice into the atmosphere and forming the caldera...
Climate change, combined with population growth, is expected to exacerbate water scarcity globally. In the Columbia River basin (CRB), streamflow is managed for multiple objectives with a network of dams and reservoirs distributed throughout the basin that may mitigate climate change effects on water scarcity. This study quantified trends in...
Estimating the abundance of long-lived, migratory animals is challenging but essential
for managing populations. We provide the first abundance estimates of endangered humpback
whales Megaptera novaeangliae from their breeding grounds in Oceania, South Pacific.
Using fluke photo-identification (1999−2004, n = 660 individuals) and microsatellite genotypes
(1999−2005, n = 840 individuals),...
Many children with developmental disabilities are not engaging in the recommended amount of daily physical activity (Pan, 2008; Shields, Dodd, & Abblitt, 2009; Whitt-Glover et al., 2006), which can lead to additional health disparities and decreased quality of life for children in this population (Field & Jette, 2007). The relationship...
Juvenile Oncorhynchus mykiss migrate extensively in freshwater during fall. We used individual tagging to study the spatial origin, influences, and outcomes of fall migration on fish that emigrated from summer rearing tributaries during fall (early-emigrants) and those that did not (late-emigrants) in the South Fork John Day River, Oregon. Fall...
We present a high-resolution Gravity Recovery and Climate Experiment (GRACE) mascon solution for Gulf of Alaska (GOA) glaciers and compare this with in situ glaciological, climate and other remote-sensing observations. Our GRACE solution yields a GOA glacier mass balance of -65 ± 11 Gta⁻¹ for the period December 2003 to...
We present an optical method (optical current meter) to measure the longshore
component of nearshore surface currents by measuring the alongshore drift of persistent
sea foam in the surf zone. The method uses short time series of video data collected from
an alongshore array of pixels. These space-time data are...
Aquatic fecal contamination from non-point sources impairs environmental health and serves as a vehicle for transmission of waterborne disease, resulting in economic losses worldwide. Accurate methods of diagnosing fecal pollution and its source are needed to prevent human exposure, remediate pollution, and reduce economic impacts. In order to obtain this...
Twenty-four woven Pre-Columbian textiles in the
Apparel, Interiors and Merchandising Department (AIM) of
Oregon State University were reported to be from Ancon,
Peru. A methodology was developed to confirm the exact
provenance of the AIM textiles. Technical fabrication
characteristics were utilized to describe certain known
Ancon woven textiles and to...
Wood is a major pool of organic carbon that is highly resistant to decay, owing largely to the presence of lignin. The only organisms capable of substantial lignin decay are white rot fungi in the Agaricomycetes, which also contains non–lignin-degrading brown rot and ectomycorrhizal species. Comparative analyses of 31 fungal...
