FIGURES 



1. Track chart for Townsend Cromwell cruises 4, 5, and 6. The large, 

 numbered dots indicate the locations at which both hydrographic and 

 BT (bathythermograph) casts were made; the smaller dots indicate 

 locations at which only BT casts were made 



2. Surface temperatures (° C.) and salinities (°/oo) (upper panel) and BT 

 temperature (° C.) section (lower panel) for Townsend Cromwell 

 cruise 4 along long. 148° W. The bottom of the ML (mixed layer) is 

 shown by the starred line in the lower panel 



3. Surface temperatures (° C.) and salinities (°/oo) (upper panel) and BT 

 temperature (° C.) section (lower panel) for Townsend Cromwell 

 cruise 4 along long. 151° W. The bottom of the ML (mixed layer) is 

 shown by the starred line in the lower panel. 



Surface temperatures (° C.) and salinities ("^/oo) (upper panel) and BT 

 temperature (° C.) section (lower panel) for Townsend Cromwell 

 cruise 4 along long. 154° W. The bottom of the ML (mixed layer) is 

 shown by the starred line in the lower panel 



Surface temperatures (° C.) and salinities (°/oo) (upper panel) and BT 

 temperature (° C.) section (lower panel) for Townsend Cromwell 

 cruise 4 along long. 157° W. The bottom of the ML (mixed layer) is 

 shown by the starred line in the lower panel. 



6. Surface temperatures (° C.) and salinities (°/oo) (upper panel) and 

 zonal BT temperature (° C.) section (lower panel) for Townsend 

 Cromwell cruise 4 between stations 7 and 7A, 25 and 26. The bottom 

 of the ML (mixed layer) is shown by the starred line in the lower 

 panel 10 



7. Surface temperatures (° C.) and salinities (°/oo) (upper panel) and 

 zonal BT temperature (° C.) section (lower panel) for Townsend 

 Cromwell cruise 4 between stations 37 and 40. The bottom of the ML 

 (mixed layer) is shown by the starred line in the lower panel 11 



8. Surface temperatures (° C.) and salinities (^/oo) (upper panel) and BT 

 temperature (° C.) section (lower panel) for Townsend Cromwell 

 cruise 5 along long. 148° W. The bottom of the ML (mixed layer) is 

 shown by the starred line in the lower panel 12
