  • Production and partitioning of organic matter during simulated phytoplankton blooms

    Creator:
    Wetz, Michael S.
    Abstract:
    Few studies have examined the partitioning of organic matter in upwelling systems, despite the fact that these systems play a key role in carbon and nitrogen budgets in the ocean. We examined the production and partitioning of phytoplankton-derived organic matter in deck incubations off Oregon during the upwelling season. During...

  • Dynamics of organic matter production and degradation during coastal diatom blooms

    Creator:
    Wetz, Michael S.
    Abstract:
    Experiments were designed to answer key questions about diatom-derived organic matter cycling (i.e., production and degradation) in coastal systems. Dissolved organic matter (DOM) production was examined in axenic batch cultures of five diatom species. Dissolved organic carbon (DOC) release rates varied between species, but were significantly higher for all species...
