  • Measuring Bubble Pressure in Glacier Ice

    Creator:
    Clonch, Cameron E.
    Abstract:
    Recent observations of tidewater glaciers find that the currently accepted model for predicting ice melt vastly underestimates observed melt rates. The release of pressurized air bubbles into the ocean from pores in the ice is one process that can amplify glacier melt. To incorporate this process into models, we need...

  • Estimating basal glacier conditions using internal layer slopes

    Creator:
    Carroll, Georgia
    Abstract:
    Ice-penetrating radar produces detailed images of the internal ice layers in a glacier. Because the layers form from each year's snowfall, the curving of the internal layers is a record of the climate conditions that the glacier experienced as it flowed throughout the millennia. The Hiawatha Glacier lies on top...

  • Mother Nature Branches Out: A Children’s Story Exploring Literacy Development and Social Change

    Creator:
    Ford, Erin E.
    Abstract:
    “Mother Nature Branches Out” is a children’s story that incorporates developmental concepts important for early literacy development as well as developing skills related to social change and environmental activism. Incorporating and teaching about climate change within the context of a children’s story helps to expand the lens through which children’s...

  • Effect of Zero-and-Low Calorie Sweeteners on Retronasal Odor Enhancement

    Creator:
    Schenk, Erin E.
    Abstract:
    This study aimed to investigate the relationship between taste and odor through the phenomenon called retronasal odor enhancement by sweet taste. The specific sweet tastants used were zero or low calorie sweeteners. Experiment 1 used an aqueous model system where subjects sampled of vanilla solutions with and without five different...

  • A Needs Assessment Survey of Small Farmers in Oregon's Mid-Willamette Valley

    Creator:
    Wever, Erin L.
    Abstract:
    OSU Extension provides important educational services to members of the agricultural community. Programming options can be guided by needs assessment surveys, which are used to determine gaps in knowledge and understanding for communities. The objective of this study was to develop and execute a survey to gather information on: 1)...

  • Understanding Drivers of Glacier Length Variability Over the Last Millennium

    Creator:
    Huston, Alan C.
    Abstract:
    Changes in glacier length reflect the integrated response to local fluctuations in temperature and precipitation, but when do such changes indicate forced climate change, and when do they indicate natural variability? In this study, we simulate the past ~1000 years of glacier length variability across the globe using the 3-stage...

  • Freeze-thaw cycles in permafrost soils and their impacts on the climate: A literature review

    Creator:
    Bergmann, Maya K.
    Abstract:
    Climate change is occurring at an increasingly rapid rate, with impacts heightened in the cold regions of the world including the Arctic. Warming effects are widespread, with one impacted process – freeze-thaw cycles – increasing in frequency and potentially triggering additional changes in permafrost soils that have previously acted as...

  • Determination of Stable Isotope Analysis as a Valid Method for Identifying Tick Blood Meals

    Creator:
    Morrison, Erin
    Abstract:
    In order to decrease Lyme disease prevalence it is crucial to understand the role of the black-legged tick, Ixodes scapularis, and its hosts within the ecosystem. This study sought to validate stable isotope analysis as a method of determining tick blood meals by comparing the δ¹³C and δ¹⁵N of the...

  • Survey of Cyanophages: A Study of the Bacteriophages associated with Pacific Northwest Cyanobacterial blooms

    Creator:
    Riscoe, Erin W.
    Abstract:
    Cyanobacterial blooms are a growing concern in the Pacific Northwest because of their threat to watershed health and drinking water supplies. Bacteriophages are pathogens of bacteria and may contribute to the growth and decline of seasonal blooms. Bacteriophage S-CRM01, a lytic T4-type myophage, has been isolated from a freshwater strain...
