been constructed with a series of overlays of actual grid track, environ¬ 
mental data, and parametric analysis sectors. This pictorial summary of 
grid activities has been photographed; these photographs serve as figures 
in this report. The negatives are included and for filing in the Washington 
office. The grid was divided into nine analysis areas (see Appendix A for 
coordinates of these divisions). 
Eastern Grid Survey 11 
Discussion: 
Sixty degree temperature, winds from the NTW at 8-20 knots, and heavy 
♦ 
overcast held throughout the survey. One interesting area was encountered 
at ceu 3^°56 ? N - 122°50 T W where two slicks were noted. The slicks were 
apparently the result of a confluence of water masses or convention cells. 
Red Phalaropes were abundant on these slicks. Of interest during this and 
EGS-10 was the complete lack of Velleta, the ,f sailors before the wind.' 1 It 
was abundant in June. 
Diurnal observation 114*5 hours and 1054 miles were recorded. Two 
species, Leach ! s Storm Petrels and Red Phalaropes accounted for 85-7 percent 
of 774 birds recorded. The distribution of these two species prompted us 
to adopt a new system of grid data analysis. The North-South dividing line 
has been replaced by two north-south lines yielding three east west sections. 
Appendix A lists coordinates for divisions and labeling for the sectors. 
The reader is referred to Figures 2 and 3 graphic illustration of the 
advantages of the new analysis system. It allows a more refined and de¬ 
tailed breakdown of quantitative distributions within the grid.
