Schmitt's (1981) temperature-salinity data for North Atlantic Central Water. The data were digitized from Schmitt's Figure 1, to a tolerance of about half the symbol size in that diagram. Schmitt reported the original data source as a cruise of the vessel T. G. Thompson in 1970, and a location of 25.2N and 35.8W.
