Question

Within the upper 200 m or so of the surface layer seen in Figure 13B-3, the temperature remains nearly the same with increasing depth (i.e., isothermal). This isothermal layer thickens through fall, winter, and often into early spring because of the net loss of heat to the air above. Surface ocean water cools and becomes more dense as it loses heat, thereby enhancing convection as the cooled water sinks. The convection promotes the mixing of waters at the base of the surface layer. This, at least partially, explains the salinity profiles showing that ocean water at the surface has salinities ______ those observed in late summer. This salinity pattern, in part, might be due to seasonal variations in precipitation from passing storms.
