  abstract = {{W}hen phytoplankton growth is limited by low nutrient concentrations, full-depth-integrated phytoplankton biomass increases in response to intermittent mixing events that bring nutrient-rich waters into the sunlit surface layer. {H}ere it is shown how oscillatory winds can induce intermittent nutrient entrainment events and thereby sustain more phytoplankton at fronts in nutrient-limited oceans. {L}ow-frequency (i. e., synoptic to planetary scale) along-front wind drives oscillatory cross-front {E}kman transport, which induces intermittent deeper mixing layers on the less dense side of fronts. {H}igh-frequency wind with variance near the {C}oriolis frequency resonantly excites inertial oscillations, which also induce deeper mixing layers on the less dense side of fronts. {M}oreover, we show that low-frequency and high-frequency winds have a synergistic effect and larger impact on the deepest mixing layers, nutrient entrainment, and phytoplankton growth on the less dense side of fronts than either high-frequency winds or low-frequency winds acting alone. {T}hese theoretical results are supported by two-dimensional numerical simulations of fronts in an idealized nutrient-limited open-ocean region forced by low-frequency and high-frequency along-front winds. {I}n these model experiments, higher-amplitude low-frequency wind strongly modulates and enhances the impact of the lower-amplitude high-frequency wind on phytoplankton at a front. {M}oreover, sensitivity studies emphasize that the synergistic phytoplankton response to low-frequency and highfrequency wind relies on the high-frequency wind just below the {C}oriolis frequency.},
