  • Comparative study of the population dynamics, secondary productivity, and reproductive ecology of the euphausiids Euphausia pacifica and Thysanoessa spinifera in the Oregon upwelling region

    Creator:
    Gutierrez, Jaime Gomez
    Abstract:
    I compare the seasonal abundance variation, population dynamics, fecundity, egg hatching mechanism and success, and apostome ciliate parasites of the euphausiids Euphausia pac?fica and Thysanoessa spinfera from the Oregon coast, USA. Community structure and nearshore distributions were examined from bi-weekly oceanographic surveys (1970-1972). This region has a strong cross-shelf change...

  • Sea-air CO₂ flux variability on the northeast Pacific continental margin

    Creator:
    Evans, Wiley
    Abstract:
    Carbon dioxide (CO₂) fluxes between the ocean and atmosphere on continental margins are difficult to diagnose because these regions experience large variability over spatial and temporal scales spanning meters to basins and hours to years, respectively. In a global sense, continental margins could represent a significant atmospheric CO₂ sink, equivalent...

  • Ecological subsidies to rocky shore communities : setting the stage for community dynamics in the Northeast Pacific

    Creator:
    Krenz, Christopher
    Abstract:
    This dissertation focuses on the importance of pelagic subsidies in the Northeast Pacific to rocky shore community regulation. My results document the patterns of pelagic subsidy supply, determine if those subsidies are correlated with community structure, and examine if community regulation differs between areas of high- and low-subsidies. Understanding how...

  • Structure-function analysis of the vaccinia virus I7L proteinase

    Creator:
    Moerdyk, Megan J.
    Abstract:
    Vaccinia virus is the prototypic member of the Orthopoxvirus genus. It undergoes a complex replication process where a key step in the transition from immature virion to intracellular mature virion is the cleavage of the major core protein precursors. The product of the I7L open reading frame (ORF) is a...

  • Impact of tropical instability waves on nutrient and chlorophyll distributions in the equatorial Pacific

    Creator:
    Evans, William Wiley
    Abstract:
    Tropical instability waves (TIWs) are prominent seasonal features in both the equatorial Pacific and Atlantic Oceans. This work quantifies their role in modulating the distributions of nutrients and phytoplankton biomass. Using an eight year record of biannual ship observations along the Tropical Atmosphere Ocean (TAO) buoy array, cruise sections crossing...

  • The spectral backscattering properties of marine particles

    Creator:
    Whitmire, Amanda L.
    Abstract:
    The inherent and apparent optical properties of different ocean regimes are the basis for all optical remote sensing of the ocean. Ecological information derived from remote sensors therefore relies on having a detailed understanding of how particulate backscattering and absorption contribute to the bulk optical signal. The absorption characteristics of...

  • Seconds to hour scale photosynthetic responses in marine microalgae

    Creator:
    Laney, Samuel R.
    Abstract:
    Our view of phytoplankton has historically revolved around their inability to control their location in space. The term phytoplankton itself underscores this particular difference between phytoplankton and their sessile terrestrial counterparts. Yet there are other differences between land plants and the phytoplankton that are perhaps equally important, beyond this sessile-planktonic...
