  • Visualizing Rivers: An Interactive Map of United States Water Sheds

    Creator:
    Burk, Bailey K.
    Abstract:
    An interactive map of important watersheds in the United States was created for use as a teaching tool in an estuarine ecology class. Figures and explanations of important factors influencing river ecology were created using data downloaded from the U.S. Geologic Survey. This interface serves as a visualization of biological,...

  • Microbial Abundance and Community Analysis in Devil’s Hole, Harrington Sound, Bermuda

    Creator:
    Denman, Carmen C.
    Abstract:
    Microbial activity within elevated CO2 and oxygen depleted environments changes with density driven stratification overturn in the seasonally anoxic region of Devil’s Hole, Bermuda. The temperature gradient developed during the summer months creates a natural laboratory to study bacterial and virus population density and microbial community dynamics in the anoxic...

  • Evaluation of ECOSTRESS products for estimation of leaf and grape water stress for Southern Oregon vineyards

    Creator:
    Swafford Steffensen, Collen
    Abstract:
    Accurate estimation of water stress in vineyards could prove vital for optimizing irrigation and grape quality in a changing climate. The ECOsystem Spaceborne Thermal Radiometer Experiment on the Space Station (ECOSTRESS) offers potential to remotely sense vineyard water stress but lacks validation against in-field measurements in vineyards. In this study,...

  • 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...

  • The Usefulness of Stable Water Isotopes in Improving Drought Prediction

    Creator:
    Adams, Logan
    Abstract:
    Drought represents an import part of natural hydrologic cycles that govern the rate and transportation of water on global and regional scales. (Trenberth, et al. 2015) Agriculturally, drought represents a threat to crop production and can endanger political and economic stability through the loss of resources and the threat of...

  • Kinetics of plankton respiration across gradient of anoxic to oxic conditions

    Creator:
    Jayawickrama, Clare
    Abstract:
    Ocean deoxygenation is predicted to increase in severity over the next few decades, posing a threat to marine life and fishing economies. Improved predictions of ocean deoxygenation depend on a better understanding of the biogeochemical mechanisms that underly this process. Within the realm of biogeochemical mechanisms, this project specifically investigated...

  • Science Education Through Comics: Improving Understanding of Current Marine Environmental Issues

    Creator:
    Schwarz, Zale
    Abstract:
    According to a 2017 Pew Research Study, 44% of adults in America say that they do not feel informed enough about science to understand news and new discoveries discussed on the media (Funk et al. 2019). This is concerning, because adults are not just passive consumers of media; among other...

  • Statistically Downscaled Precipitation Water Isotope Time Series at NEON Study Sites

    Creator:
    Spencer, Lindsey
    Abstract:
    The National Ecological Observatory Network (NEON) provides open access data products including sub-daily precipitation amounts and biweekly stable water isotope concentrations at sites across the United States. Stable water isotope (ẟ2H, ẟ18O) concentrations are often used in hydrometeorological studies and models, however the relatively infrequent biweekly sampling intervals of NEON...

  • Artistic Interpretation of the Significance of Human Breast Cancer Cell Vinculin Distribution in Different Extracellular Matrix Conditions

    Creator:
    Hsiao, Yu-Tin
    Abstract:
    There are clues that suggest human breast cancer cells use collagen fibers to migrate, and vinculin is a transmembrane protein associated with how cells attach to their environment. Therefore, immunostaining for the vinculin will shed some light in how human breast cancer cells are attaching to their environment. Immunostaining for...
