“…On the other hand, in the downstream of these nutrient streams, several microstructure surveys have observed relatively strong turbulence in the thermocline (Nagai et al, 2009(Nagai et al, , 2012Nagai, Tandon, et al, 2015); Inoue et al 2010), which induces nutrient diffusive fluxes of O(0.1 mmol N·m −2 ·day −1 ) (Inoue et al, 2010;Kaneko et al, 2012Kaneko et al, , 2013. Recent microstructure surveys have found very strong turbulence in the Tokara Strait (Nagai et al, 2017;Tsutsumi et al, 2017), some of which are associated with the high-vertical-wavenumber near-inertial internal waves.
