Galapagos Storm Petrel 
This bird was the dominant one following the ship throughout most 
of the trip. 
White-faced Storn Petrel 
Most of these birds were south of the large concentration at 5°N 
and occurred only on the eastern-most leg of the trip. 
Fork -tailed Petrel (?) 
This is a questionable sighting because of location but Ed Coughran 
and I both described the bird separately and felt that we were fairly 
sure of our observation. 
Sooty Tern 
Records for this trip indicate that the Sooty Terns were using the 
areas of 5°-L0°H and 5°-10 o S, and were virtually absent from the remaining 
areas. Most flocks that were closely observed contained immatures in¬ 
dicating they were from spring or summer breeding populations. 
Mammals and Turtles 
Seven hundred five mammals of about eight species, and 12 turtles 
of two species were recorded (TABLE 12). 
Other Data Collecting Activities 
Routine collections of data proceeded as on previous EASTROPAC 
trips- Only one of the continuous recording environmental data buoys 
that had been anchored by the January EASTROPAC trip was found and 
serviced. A computer aboard ship ma.de some of the oceanographic data 
available* but special programs had to be written depending on the 
type of analysis desired. These data can be obtained from BCF or 
Scripps. On this trip two special projects were carried out. One was 
a current study by Dr. B. A. Taft on the 29 th August to 2 September 
near the Equator. The other was a vertical distribution study of a 
pelagic snail off the southern end of Guadalupe Island, carried out by 
Mr. Charles B. Miller.
