Última Relaxation of wind stress drives the abrupt onset of biological carbon uptake in the Kerguelen Bloom: a multisensor approach ArchiMer Pellichero, Violaine; Boutin, Jacqueline; Claustre, Hervé; Merlivat, Liliane; Sallée, Jean‐baptiste; Blain, Stéphane. We deployed sensors for physical and biogeochemical measurements on one Eulerian mooring and two Lagrangian biogeochemical Argo‐floats on the Kerguelen Plateau. High temporal and vertical resolution measurements revealed an abrupt shoaling of both the mixed‐layer depth and mixing‐layer depth. The sudden stratification was concomitant with the start of significant biological activity detected by chlorophyll‐a accumulation, oxygen oversaturation and dissolved inorganic carbon drawdown. The net community production computed in the mixing‐layer during the onset period of 9 days was 119±7 mmol m‐2 d‐1. While it is generally admitted that bloom initiation is mostly driven by the onset of positive heat fluxes, our results suggest this is not a sufficient...
