Sooty Shearwater ( Puffinus griseus) # Obs. = 1 6 
Birds began to appear regularly some 50 miles east of the Grid area. 
Puffinus sp. # Obs. = 1 
The log reads n [29 July] Brown mantle - dark crissum, dark throat 
& neck, white underwings. Looked larger than P. jd. opisthomelas but was 
too fast for [P.] creatopus (probably colored wrong also) could it be 
Townsends (?)rcheck" - DeLong. 
Cook Petrel ( Pterodroma cooki) # Obs. = 5 
These birds appeared shortly after leaving the Grid. The bulk of 
the population appears to be centered around 125° W at this latitude and 
probably does not come much further east than 120° W. 
White-rumped Storm Petrel # Obs. = 33 
Storm Petrel sp. # Obs. = 26 
Storm Petrel populations remained fairly high for all July 29> but 
were absent inside the Channel Islands.

EASTERN GRID SURVEY #10 
The Grid area was entered from the west side just south of Point Ginko 
on 19 July at 1226 hours. Observations on 19 and 20 July, before beginning 
the nominal cruise track, have not been included in the regular summary 
statistics but are discussed in the species accounts. (See Table #1 for 
summary of this section.) The extreme northwest portion of the first leg 
was not covered due to allowances made for the helicopter rendezvous. 
On the morning of 23 July the ship was making maneuvers 4-8 miles south 
and southeast of Point Dogwood awaiting the helicopter transfer. Two 
hours of observations in this area are not included in the statistical 
Grid summary but are clearly an important part of the Grid area and are 
considered in the text. (See Table #1 for a summary of these observations.) 
[See Figure #1 - Cruise Track.] 
Over the 891 diurnal miles of nominal Grid track, 378 birds of 15 
species were observed. Sixteen specimens of six species were collected. 
An additional l43 birds over 150 diurnal miles were logged in the non¬ 
track areas. Forty-eight birds were recorded during 7*3 hours of nocturnal 
watch. (See Table #2). [See Table #1 for observation summaries for all 
areas.]
