The seasonal biological surveys of 1971 / John C. Ayers, Samuel C. Mozley, John A. Stewart.

The seasonal surveys of 1971 apparently caught, in April the end of the
spring diatom bloom as evidenced (Table 4) by 58 dominant or codominant occurrences of diatoms out of a total of 97 such occurrences.
Green algae came into dominance in the July survey and continued dominant
in the warm water of the early September survey. By November they had fallen
from prominence with only 7 occurrences as dominants or codominants out of a
total of 106.
Flagellates were most heavily dominant in the April survey, declined in
July, did not attain to dominant or codominant status in September, and were
resurgent in November.
Blue-green algae attained dominant or codominant status only in the
November survey when the coccoid blue-green, Aphanothece sp,, reached such
rank on two occasions.
Master Lists of Phytoplankters Collected During the Surveys. Table 5.
presents in alphabetical order the complete lists of phytoplankters taken
during the four surveys of 1971. Over time, such species lists serve as
means by which to watch for changes in population composition.
