Observations of chlorophyll, fluorescence, phytoplankton species composition, and occurrence of foam and red tide patches were available from a series of stations in Monterey Bay.
Solid symbols (dashed line) represent total chlorophyll collected weekly
from the Santa Cruz Municipal Wharf from August 15 to December 15, 2007 (labelled SCW on the inset map); the solid line represents daily
chlorophyll fluorescence data for the same time period from the M0 mooring. Red bars along the x-axis denote visual observations of red tides from
stations depicted in the map (inset), with the letters above the red bars denoting dominant species (C = Ceratium spp., Co = Cochlodinium spp.,
A=Akashiwo sanguinea). Green bars denote visual observation of foam at the Santa Cruz Municipal Wharf. The bird strandings coincided with the
largest red tides (note the chlorophyll and fluorescence) dominated exclusively by A. sanguinea and co-occuring with foam.
