  3. Nitrogen cycling in the South Atlantic and South Indian Oceans investigated using nitrate isotopes: implications for nutrient supply, ocean fertility, carbon export, and climate by Marshall, Tanya

    Published 2024
    “…A novel application of the dual isotopes of nitrate reveals the occurrence of three (sub)mesoscale mechanisms of upward nitrate supply; entrainment at the edges of a mesoscale anticyclonic eddy, inshore upwelling likely driven by a frontal eddy, and overturning at the offshore edge of the current core likely driven by coupled mesoscalesubmesoscale instabilities. The intensity and (sub)surface expression of these nutrient supply events are not always apparent in the hydrographic data, highlighting the utility of the nitrate isotopes for exploring physical ocean processes. …”
