Methods : One-man diurnal observations were made from the helicopter 
deck on the 31 st through the 2nd., and largely from the wing of the 
bridge for the remainder of the grid. Two periods of regular under¬ 
way watch were conducted from the ,? BOSTON WHALER". Nocturnal watches 
were held on two nights as conditions warranted, from the spotlight 
located on the Port Quarter Deck. Birds were collected from the 
n BOSTON WHALER" on the afternoons of 3 ? 5 5 & 7 November, and stray 
land bird specimens were collected on the deck of the ship. No BT T s 
were taken. Other methods and procedures followed those established 
on previous cruises. 
Cruise Track : (see FIGURE #l) 
The first part of the nongrid leg directly south of San Francisco 
was covered at night. Most of 31 October was spent in nongrid areas 
just north of Grid Section "T". A number of Herring Gulls followed the 
ship from this nongrid area into the northeast corner of the Grid. The 
nominal Grid Track was followed closely with the following exceptions: 
At sunset on the 6th, 30 miles east of "Larch", a revised SE course was 
taken such that the remaining two full days of observations could be 
distributed in those Grid subdivisions which would benefit from the 
coverage. This planned deviation is a statistical practice which is 
becoming more and more important, since the usefulness of the 9 
division breakdown depends largely on equal sectional coverage during 
the daylight hours. 
Excellent cooperation and assistance was received from Captain 
Keiser, the Deck Force, and all personnel concerned with the operation. 
Conditions : This cruise enjoyed the most consistently favorable weather 
and operating conditions yet encountered in the area. A weak high
