Figure 12.--Vertical distributions of properties on cruise TO-58-2, parts 1, 2, and 3, along section B-B (see 

 fig, 8); depth scale in m. 



to the west of the ridge only (fig. 16E), 

 instead of on the ridge and westward as in 

 figures 4F and lOF. The few available values 

 for micronekton standing crops are of the 

 same order as those for TO-58-1, i.e., higher 

 than average for the eastern tropical Pacific 

 (fig. 16E). 



For part 2 of the cruise, after the Tehuan- 

 tepecer, there are figures of only two hori- 

 zontal distributions, surface current and sur- 

 face temperature. Figure 17A shows the 

 expected current -pattern in the north and 

 variable weak surface current in the region 

 south of 14° 40' N. between meridians 96° and 

 95° W. Figure 17B shows the familiar meri- 

 dional arrangement of isotherms associated 

 with north-south ridging in previous charts, 

 and a cold center in mid-Gulf, as in figure 



16B and previous charts. Figure 17B also 

 indicates continuation of higher than average 

 surface temperatures from TO-58-1 in May 

 and June: it shows some water over 29° C., 

 higher than any appearing in long-term average 

 charts for the months of January and Febru- 

 ary. 



Vertical distributions of properties 



The east-west section A-A as shown in 

 figure 15A is not quite comparable with such 

 sections for the other cruises; it bends fur- 

 ther south between meridians 96° and 95° and 

 goes no farther east, because of interruption 

 to part 1 of the cruise by bad weather. The 

 section A-A in figure 15B is not entirely 

 comparable either, because no observations 

 were made west of 96° on part 2 of the cruise.
