Objective:
In Year 2 of the CEER-GOM project, the remote sensing of water quality component still focused on the Pensacola Bay system. The primary goals are to develop algorithms of estimating chlorophyll concentrations using Landsat TM and ETM+ data. The algorithm development process included two approaches: traditional band combination and neural network analysis. With the algorithms established, maps of chlorophyll concentration in Pensacola Bay were created. Findings from the hyperspectral data analysis from Year 1 of the project were put together in a manuscript for publication. I also was involved in a collaborative research effort between the two Estuarine and Great Lakes Program (EaGLe) groups.
Progress Summary:
Development of Algorithms of Estimating Chlorophyll Concentration Using Landsat TM/ETM+ Data
The chlorophyll map created using the band combination model is shown in Figure 1. The chlorophyll map created using the neural network model is shown in Figure 2.

Field Data Collection
Close-range hyperspectral data collection was conducted along with the U.S. Environmental Protection Agency Gulf Ecology Division's monthly sampling over Pensacola Bay on June 4, 2003. Close-range hyperspectral data collection also was conducted in a collaborative research effort in North Inlet, SC, on August 13, 2003.
Future Activities:
We will continue to develop algorithms of estimating chlorophyll concentrations using Landsat TM and ETM+ data. In addition, manuscripts are in review for publication in a special issue on the EaGLe project in the International Journal of Remote Sensing.
