Published in 2017 at "Journal of Geophysical Research"

DOI: 10.1002/2016jc012400

Abstract: When 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. Here, it is shown how oscillatory winds… read more here.
