  • Predicting Fish Recruitment in the Northeast Pacific Using Climate Indices

    Creator:
    Riley, Shannon L.
    Abstract:
    Predicting recruitment, which is dependent on parent stock size and climate, is vital for forecasting productivity of fish stocks. The effects of climate can be analyzed via the use of climate indices. Three climate indices, the Pacific Decadal Oscillation, the North Pacific Gyre Oscillation, and the Oceanic Niño Index, describe...

  • Comparing Sediment Microbial Communities of Arctic Beaver Ponds to Tundra Lakes and Streams

    Creator:
    Shannon, Kelly
    Abstract:
    In recent decades the habitat of North American beaver (Castor canadensis) has expanded from boreal forests into pan-Arctic tundra ecosystems. It is unknown how the advance of beavers into Arctic watersheds will impact microbial communities responsible for the mineralization of organic matter (OM), which has implications for carbon cycling. To...

  • Communication Planning for Cooperative Terrain-Based Underwater Localization

    Creator:
    Anderson, Jacob
    Abstract:
    This thesis presents a decentralized communication planning algorithm for cooperative terrain-based navigation (dec-TBN) with autonomous underwater vehicles. The proposed algorithm uses forward simulation to approximate the value of communicating at each time step. The simulations are used to build a directed acyclic graph that can be searched to provide a...

  • Marine Nitrogen Subsidies to Terrestrial Systems: Transport Through Wrack Deposition

    Creator:
    Traylor, Andrew
    Abstract:
    Fluctuations in one system affect adjacent systems; mechanistic understanding of linkages helps conservation efforts be more effective by focusing on influential species and areas that facilitate connections between ecosystems. This study explored marine-derived nutrient inputs to adjacent terrestrial communities. We quantified wrack (seaweed and other organic matter) deposition at sites...

  • Analysis of Convolutional Neural Network Image Pre-processing Methods

    Creator:
    Jacobsen, Matthew
    Abstract:
    Oceanic plankton have both a large impact on our oceans health and atmo- spheric balance of Co2. The overall health of planktonic life is determined by many physical, chemical, and ecological factors, that drive taxonomic abundances and the relative amount of non-living biomass called detritus. Recent advances in microscopic imaging...

  • Variability in the condition of juvenile Antarctic krill, Euphausia superba, at the Western Antarctic Peninsula

    Creator:
    Shah, Radhika S.
    Abstract:
    Antarctic krill, Euphausia superba, are a highly abundant zooplankton species found in the Southern Ocean. They are a key food choice for higher trophic levels and are important consumers near the base of the food web. Changes to the environment of the Western Antarctic Peninsula (WAP), as a result of...

  • High-resolution Biological Net Community Production in the Pacific-influenced Arctic: A Multi-method Comparison

    Creator:
    Cynar, Haley
    Abstract:
    Patterns of primary productivity in the Arctic are expected to change with continued warming, yet productivity measurements are historically limited, both spatially and temporally. An established method of measuring net biological oxygen production, which can be used to estimate net community production (NCP) rates, is with an equilibrated inlet mass...

  • Using DNA metabarcoding to describe biodiversity and disease dynamics

    Creator:
    Massey, Aimee L.
    Abstract:
    Land-use change, particularly in the form of the conversion of primary forest to forest-matrix systems, alters species communities and species interactions. Describing these often complex and nuanced species responses is one of the great challenges in ecology. Another complementary challenge is finding and using the most efficient means for collecting...

  • Proteomic Profiles of Circulating Exosomes as Biomarkers for Disease Detection in Canine Osteosarcoma

    Creator:
    Brady, Jacqueline V.
    Abstract:
    Osteosarcoma (OSA) is the most common primary skeletal tumor in dogs accounting for 85% of bone tumors and nearly 6% of all canine neoplasms. They are highly aggressive tumors that carry a poor prognosis despite intensive treatment, highlighting the need for more effective diagnostic and therapeutic tools. Recent research in...
