 OVERVIEW OF SAMPLING PROGRAM IN NORTH FLORIDA COASTAL AREAS 



1. Apalachicola Bay System 



a. Physico-chemical measurements . (All stations, surface and bottom; March, 

 1972-present; minimum at monthly intervals. Temperature (air), river flow and 

 rainfall data from Atlanta, Georgia, to Apalachicola, Florida, (monthly, 1920-- 

 present) are also on files in the data base)
