 tains additional information on the Equatorial Program. 



The NORPAX Equatorial Program began with a 3-month 

 test shuttle across the Equator between Honolulu, Hawaii, and 

 Papeete, Tahiti. Measurements have been or are being made 

 from ships, aircraft, moored instruments, drifters, and island 

 stations as indicated in figure 23. Figure 24 shows some pre- 

 vious transequatorial XBT section locations. Figure 25 is an 

 earlier profile of dynamic topography along 155°W.) For ex- 

 ample, the first leg of the RV Kana Keoki, which took place 

 November 9-29, 1977, took 61 CTD profiles to 1,000 m and 

 intermediate XBT casts; launched radiosonde balloons twice a 

 day; deployed 11 satellite-tracked drifting buoys, 4 ocean-bot- 

 tom seismometers, 2 bottom-pressure recorders, 6 bottom-cur- 

 rent meters, and 2 surface-bottom moorings; and continuously 

 recorded surface temperature and salinity. The purpose of the 

 data collected during this preliminary phase is to aid in long- 

 term equatorial planning.
