Paper Abstract
QuikSCAT satellite based vector wind data were used to examine wind influence on SeaWiFS derived chlorophyll a
(chlorophyll) surface distribution in the northern Gulf of Mexico waters influenced by the Mississippi and
Atchafalaya Rivers, the largest in North America. Short-term satellite derived wind field revealed a systematic shift
in direction and amplitude of the winds during a cold front passage in March 2002 that strongly influenced the
surface chlorophyll distribution. Both the offshore extent and westward transport of enhanced surface chlorophyll
biomass increased following the frontal passage. Monthly surface wind stress derived from the 12.5 km high
resolution QuikSCAT winds mapped along with SeaWiFS derived surface chlorophyll during a low flow and a
normal river discharge year in 2000 and 2001 indicated the dominant role of river discharge in influencing the
concentration and extent of chlorophyll in the plume and inner shelf waters. However the magnitude and direction of
wind stress strongly influenced the plume orientation and the cross-shelf extent of a coastal band of elevated
chlorophyll. Wind stress also influenced the offshore cross-shelf variability in surface chlorophyll distribution.
