PELAGIC SURVEY REPORT 
This report is a preliminary analysis of the pelagic field work 
conducted by the Pacific Ocean Biological Survey Program from 07-26 
October, 1966. Any discussion of the data contained herein is purely 
speculative in nature and should not be relied upon until a more critical 
analysis, including comparison with existing and future data, can be 
made. 
Logistic support was provided by the U.S.S. Tawakoni (ATF 114 ) 
whose officers and crew cheerfully cooperated with the Smithsonian 
personnel whenever necessary. They were also responsible for the 
collection of all weather and position data. P.O.B.S.P. personnel 
included Patrick Gould (Biologist in Charge), Ken Balcomb, Brian 
Harrington, and Jim Lewis. 
Weather conditions were excellent with relatively low winds and 
calm seas except for the return trip along the Leeward Islands when 
winds reached 20-25 knots and the seas became very rough. 
A total of 1,655 miles and 146.8 hours of diurnal observations 
plus an additional 777 miles and 72.6 hours of nocturnal observations 
were completed. As in other surveys, the data was gathered over linear 
transects with the ship moving at from 10 to 13 knots most of the time. 
The general area covered was from Oahu to the Northern Grid (3 days), 
the Northern Grid Proper (6 days), the Northern Grid to Lisianski 
(2 days), and from Laysan to Oahu (2 days). This was the first time 
that pelagic observations had been made along the Leeward Islands in 
October.
