Our upwelling station was centered
at 41°N / 67° 40' W on Georges Bank. The foggy skies made it difficult
to distinguish the water color but we all agreed the closest paint match
was "Marine aqua."
How does this compare with colors at the Open
Ocean and Continental Shelf
stations? What influences ocean color?

FACScan
DATA>> At right, a plot of "Fluorescence versus Size"
shows cell types from one depth. Some samples had Prochlorococcus
("P")
and/or Synechococcus ("S")
cells. These tiny (0.6 to 1.0
micrometers) cells, undiscovered until the 1970's, are responsible
for much of the photosynthesis
in the world’s oceans. Some samples also had small eukaryotic
cells ("E").
