A Characterization of the North Atlantic STMW Layer Climatology Using World Ocean Atlas 1994 Data
The North Atlantic Subtropical Mode Water (STMW) layer was identified based on its temperature, large thickness, and small temperature gradient. Comparisons between this method and identifying the STMW layer using a density-based (i.e., potential vorticity) criteria indicate that this method success...
