itself with extending the previous tabulations, figures, and discussions to
include the seasonal surveys of 1977. Numbers of forms are listed in each
station collection in Appendix B.
As was done in the reports cited, the data on numbers of forms present
in 1977 are stratified by three depth zones and inner (treatment) and outer
(control) station groups. Stations along, or less than two miles north or
south of, a central transect extending perpendicular to shore from the Cook
Plant are defined as inner stations which might be affected by plant operation.
Stations 2 miles or more north or south of the plant are defined as north and
south reference stations or, lumped together, as outer stations. Zero to 8 m
depths are designated "Zone 0"; 8 to 16 m as "Zone 1"; and 16 to 24 m as
"Zone 2." For each depth zone there are inner and outer station groups. The
depth zones and station groups used are:
