encouragement. Field laboratory facilities and boats were supplied by the Louisiana Universities 

 Marine Consortium at generous rates. Mark LaSalle, U.S. Army Engineers Waterways Experiment 

 Station, Vicksburg, MS, provided valuable suggestions on data analysis. University of Southwestern 

 Louisiana students Rowdy Guidry, Robert Venable, and Dave Severson did much of the field 

 collections under difficult conditions.
