During the first part of SPURS-2 experiment, a cluster of autonomous instruments was deployed for a 100-day 1,800-km coordinated quasi-Lagrangian drift through the North Pacific intertropical convergence zone (ITCZ). A total of 25 instruments participated in the drift during various stages of the experiment: a WHOI Wave Glider, an APL Seaglider, an APL Lagrangian float, a UW Profiling APEX float, 3 AOML Salinity drifters, and 18 SIO SVP(-S) drifters. The cluster conducted multi-platform observations of the ocean surface boundary layer structure and dynamics in a quasi-Lagrangian frame of reference minimizing the effects of horizontal advection. We will present preliminary results of this coordinated study, focusing on the evolution of upper-ocean stratification and shear in response to storm-induced rainfall and wind bursts.
