Before revision: The Barrier layer in the ocean is a layer of water separating the well-mixed surface layer from the thermocline Sprintall, J., and M. Tomczak, Evidence of the barrier layer in the surface-layer of the tropics, Journal of Geophysical Research-Oceans, 97 (C5), 7305-7316, 1992.. The thickness of the layer is defined as the difference between mixed layer depth (MLD) calculated from temperature minus the mixed layer depth calculated using density.
