Figure 41.— Typical temperature-salinity curves of waters 

 In the Gulf of Mexico during February and March 1962. 

 That part of the curve indicating salinities greater than 

 36.00 p.p.t. has been crosshatched. The numbers along 

 each curve indicate depths In hundreds of meters. The 

 salinity maximum In each case Is SUW (Subtropical 

 Underwater).
