    • 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 

      Schmitt, Raymond W.; Asher, William; Bingham, Frederick; Carton, James A.; Centurioni, Luca R.; Farrar, J. Thomas; Gordon, Arnold L.; Hodges, Benjamin A.; Jessup, Andrew T.; Kessler, William S.; Rainville, Luc; Shcherbina, Andrey Y. (The Oceanography Society, 2015-03)
      One of the notable features of the global ocean is that the salinity of the North Atlantic is about 1 psu higher than that of the North Pacific. This contrast is thought to be due to one of the large asymmetries in the ...
