  1. Lagrangianfloat observations in SPURS-1 Andrey Shcherbina· Eric D'Asaro· Ramsey Harcourt SPURS moorings • 3D Lagrangian drifts • Hi-res. profiling 2012 2013 500km

  2. Thermohaline structure evolution Freshwater pools, high/low S intrusions S T

  3. Interleaving associated with the Underwater subduction? Barrier layers (BL) often found Ref. MLDS B.L. B.L. MLDT

  4. Composite diel cycles Salinity cycle is out of phase in summer due to entrainment? Temperature Salinity

  5. Upper-ocean stratification in SPURS:Lagrangian float observations Rain pools Submesoscaleinterleaving Diel cycle Next: Inter-comparison and synthesis with other SPURS efforts (ARGO floats, S drifters, gliders, moorings, numerical models)
