SMITHSONIAN GRID I 
Survey No* 22 
JUNE 1965 
Tills report summarizes the observations a.nd collections made at sea 
by Pacific Project personnel aboard the U.S.N.S. SHEARWATER during June, 
1965* Project personnel included Kenneth Amerman (Biologist in Charge), 
Dayle Husted and Brian Harrington, 
A total of 11*5 days were spent from Oahu to the Smithsonian Grid I, 
5 # 5 days within the grid and U days returning to Oahu* During this time 
26? hours of sunrise to sunset observations were conducted, 71 of these 
within the study grid. 
A total of 12U birds of II 4 . species were collected (Table 7). Blood 
samples were obtained from 6U of these and 105 ectoparasite collections 
were made* 
The course from Oahu was extended slightly farther east than in May 
since fairly high numbers of birds were recorded in the easternmost area 
reached last month* Comparable numbers of birds were recorded in this 
area both months* The course was continued southwest toward Christmas 
Island below 8°N to within 250 miles of that island. As expected, the 
numbers of birds increased substantially with greater proximity to the 
island* Due to the low numbers of birds observed within the Smithsonian 
Grid a straight line course was followed from the grid to Oahu, passing 
within 60 miles of Johnston Island. Numbers recorded along this path
