Global Compositing of Chlorophyll 
and Productivity 
As indicated in Section 5, part of the data 
processing planned for SeaWiFS data is to pro- 
duce global maps of phytoplankton chlorophyll. 
Before these products can be incorporated into 
RESEARCH USERS' PANEL 
GOFS and other studies, the users must under- 
stand the limitations of large-scale composite im- 
agery. Thus, a project will be required to provide 
a firm assessment of large-scale sampling statis- 
tics and to perform initial comparisons with high- 
level (binned and averaged) correlative data sets.
