  • Insights from stable isotope dynamics into the sensitivity of larval Pacific oysters to ocean acidification

    Creator:
    Brunner, Elizabeth Lev
    Abstract:
    Larvae of the Pacific Oyster, Crassostrea gigas, at Whiskey Creek Shellfish Hatchery (WCH) in Netarts Bay, Oregon, are negatively impacted by high-CO₂ water and exposure during the initial shell formation period appears to be particularly damaging. To investigate the mechanism of this early susceptibility, several cohorts of larvae at WCH...

  • Seagrasses as Potential Chemical Refugia for Acidification-Sensitive Bivalves

    Creator:
    Smith, Stephanie Rae
    Abstract:
    As the effect of ocean acidification (OA) on marine calcifiers is better understood, a range of potential mitigative strategies have been proposed, many of which are plagued by concerns of scale and feasibility. One oft-cited option is to increase the biomass of photosynthetic organisms to remove CO₂ from the water...

  • Remineralization of marine particulate organic matter

    Creator:
    Burkhardt, Brian Gary
    Abstract:
    Marine microorganisms play a significant role in the cycling of nutrients in the open ocean through production, consumption, and degradation of organic matter (OM). Carbon (C), nitrogen (N), and phosphorus (P) are essential ingredients in every known recipe for life. However, the cycling of each of these elements proceeds at...
