Funding Agency: FDACS
Duration: Short

Goals and Objectives
The overall goal of this project is to develop a real-time sensor system that can detect phosphorus concentration in terrestrial and aquatic ecosystems using reflectance spectroscopy.
Specific objectives:
1. Determine specific wavelengths to measure phosphorus concenrtation in different phosphorus phases in vegetation and water samples collected from the Lake Okeechobee drainage basin at different times of the year using reflectance spectroscopy in a laboratory setting;
2. Buuidl a real-time hyperspectral sensor prototype based on results from the objective 1 using photodiode and bandpass filters;
3. Evaluate and calibrate the P-sensor system in teh Lake Okeechobee basin area; and
4. Identify 'hot' spots in the Lake Okeechobee basin area using previously identified P absorption bands and hyperspectral aerial images.
