This project aims to study the feasibility of using hyperspectral remote sensing in the reflective regime (400 to 1000 nm) to monitor nitrogen content in water for environmental management in agricultural applications in the arid southwestern United States. The main goal of the project is to develop a correlation of laboratory-derived concentrations of nitrogen with spectral features such as absorption, first derivative reflectance, and logarithmic reflectance using hyperspectral imagery collected with an Ocean optics flame spectrometer with a flame integrated sampling system. For proof of concept, the authors are using samples collected at Ascarate Lake in El Paso, Texas. The results from this research will serve as the basis for a field pilot study where we will correlate the nitrogen, phosphate, or chlorophyll measurements will be correlated with the hyperspectral imagery data collected with field spectrometers and UAV hyperspectral sensors.
