RETROSPECTIVE STUDIES OF GREAT LAKES WATER QUALITY USING SATELLITE REMOTELY SENSED IMAGERY SATELLITE REMOTELY SENSED IMAGERY
 
Archived remotely sensed imagery represents a rich, though underutilized,resource for retrospective studies of water parameters in the Great Lakes. Advanced Very High Resolution Radiometer (AVHRR) visible and thermal infrared data formed the basis of a ten-year retrospective study (1987-1996) of surface thermal features and turbidity plumes in central Lake Superior and southern Lake Michigan. The objective was to assess the relationship of winter ice formation, coastal plume development, and thermal bar movement to cross-margin transport phenomena using the remotely sensed imagery. The AVHRR imagery provide rich details of mesoscale (100-1000 km2) surface phenomena, but the relatively coarse spatial resolution of 1.1 km2 precludes enumeration of fine scale events. Advanced data visualization products are under development to combine imagery collected simultaneously using AVHRR thermal infrared and SeaWiFS (Sea-Wide Field-of-View Sensor) ocean color imagery. This new class of products will allow us to co-locate thermal and biological fronts, greatly aiding our analyses.
