Galapagos Storm Petrel This bird was the dominant one following the ship throughout most of the trip. White-faced Storm 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°-10°N and 5°-10°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 collected. A computer aboard ship made 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 29th 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.
