  • Phosphorus control of nitrogen fixation

    Creator:
    Watkins-Brandt, Katie S.
    Abstract:
    Under conditions of fixed N-limitation, as with most oligotrophic systems, the process of biological N₂ fixation (diazotrophy) is favored, provided the necessary trace elements and vitamins are sufficient. Despite the well understood contributions of N₂ fixation in oligotrophic regions, the nutritional and ecological controls of marine diazotrophs have not been...

  • Dynamic seascapes : a quantitative framework for scaling pelagic ecology and biogeochemistry

    Creator:
    Kavanaugh, Maria T.
    Abstract:
    Understanding and modeling microbial responses and feedbacks to climate change is hampered by a lack of a framework in the pelagic environment by which to link local mechanism to large scale patterns. Where terrestrial ecology draws from landscape theory and practice to address issues of scale, the pelagic seascape concept...

  • Primary production dynamics in the North Pacific subtropical gyre

    Creator:
    Corno, Guido
    Abstract:
    The North Pacific subtropical gyre (NPSG), once considered to be a biological desert due to low primary production (PP) and its associated variability, has been found more productive and variable than previously thought. The environmental conditions controlling this relatively high PP variability are yet to be elucidated, despite important implications...
