  • Friction, frontogenesis, and the stratification of the surface mixed layer 

    Thomas, Leif N.; Ferrari, Raffaele (American Meteorological Society, 2008-11)
    The generation and destruction of stratification in the surface mixed layer of the ocean is understood to result from vertical turbulent transport of buoyancy and momentum driven by air–sea fluxes and stresses. In this ...
  • From salty to fresh—salinity processes in the Upper-ocean Regional Study-2 (SPURS-2) : diagnosing the physics of a rainfall-dominated salinity minimum
