Sea turtles are often incidentally captured in commercial fishing operations in the Atlantic Ocean. The National Marine Fisheries Service (NMFS) records and reports incidents of sea turtle capture. The figures below show the seasonal distribution and relative abundance of leatherback (Dermochelys coriacea) and loggerhead (Caretta caretta) sea turtles caught by the U.S. Atlantic longline fleet from 1992 through 1995. Figure 1 shows a map of fishing areas in the Atlantic Ocean. Table 1 shows leatherback (Lb) and loggerhead (Lh) turtle captures by month in some areas show in Figure 1. Table 2 shows captures by area. Table 3 shows CPUE (catch-per-unit-effort) values for the number of turtles caught per 1000 hooks fished, as well as whether longline fishing vessels were using chemical light sticks to attract fish at the time of capture.

Sea turtles migrate to different oceanic regions over the course of the year, and higher sea turtle capture numbers indicate a higher population of sea turtles in a given region. Which of the following observations about sea turtle migration is supported by Table 1? Some sea turtle populations:
