  • 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...

  • Comparison of radiative feedback variability over multiple time scales in climate model and reanalysis data

    Creator:
    Dalton, Meghan M.
    Abstract:
    In a steady state, the Earth's absorbed solar radiation (ASR) balances the outgoing longwave radiation (OLR) at the top of the atmosphere (TOA). In response to a radiative forcing, that is, an external perturbation to the top of the atmosphere energy balance, the Earth's climate system adjusts until reaching a...
