This research was supported by funding from the US Environmental Protection Agency (EPA STAR Grant # RD-83088001) to the Environmental Sciences Institute (ESI), Florida A&M University (FAMU), and funding from the National Oceanic and Atmospheric Administration (NOAA) to the Environmental Cooperative Science Center (ECSC) at FAMU (NOAA Cooperative Agreement # NA17AE1624). We are grateful to NASA Goddard Earth Science (GES) Distributed Active Archive Center (DAAC) for providing MODIS data. We thank Terry Haran, Rich Hucek, and Shuisen Chen for their assistance with MODIS data preprocessing including the correction of bow-tie effect. We also acknowledge Drs Larry Robinson, Jennifer Cherrier, Elijah Johnson, Ping Hsieh, and the anonymous reviewers for their insightful comments and suggestions to improve the manuscript.

N2 - Apalachicola Bay, Florida, accounts for 90% of Florida's and 10% of the nation's eastern oyster (Crassostrea virginica) harvesting. Chlorophyll-a concentration and total suspended solids (TSS) are two important water quality variables, among other environmental factors such as salinity, for eastern oyster production in Apalachicola Bay. In this research, we developed regression models of the relationships between the reflectance of the Moderate-Resolution Imaging Spectroradiometer (MODIS) Terra 250 m data and the two water quality variables based on the Bay-wide field data collected during 14-17 October 2002, a relatively dry period, and 3-5 April 2006, a relatively wet period, respectively. Then we selected the best regression models (highest coefficient of determination, R2) to derive Bay-wide maps of chlorophylla concentration and TSS for the two periods. The MODIS-derived maps revealed large spatial and temporal variations in chlorophylla concentration and TSS across the entire Apalachicola Bay.
