Figure 24-7. Correspondence Analysis on 49 Phytoplankton Species 
('00') in 9 MERL Microcosms (0) and Bay Input Water (•) from 
September 14, to December 6, 1976. 
NOTE: In some cases sample locations (microcosms) are closely adjacent and 
not all of the 10 samples per microcosm are plotted. All variable locations 
(phytoplankton species) are plotted as accurately as possible. Microcosm 
location and phytoplankton species location were closely adjacent on the lower 
right hand side of the figure until the first part of November when blooms 
occurred in the bay and in the microcosms. The arrows indicate divergence 
from non-bloom conditions to bloom conditions in November when variability 
in species composition and microcosm behavior became greater.
