In collaboration with Dr. Thomas McKenna and a graduate student Lillian Wang, this study evaluated the use of thermal satellite imagery to locate and delineate ground water discharge areas in the Inland Bays using Landsat ETM+ imagery. The area of investigated in shown in the map below.
Using ENVI and an ERDAS Imagine ATCOR2 module, surface water temperatures were calculated and compared to buoys. Landsat ETM+ winter imagery was successful in identifying ground water discharge locations as shown in the map that follows. The areas labeled were examined as potential locations of discharge.
Using satellite imagery to locate ground water discharge locations is cost effective in comparison to traditional in situ ground water sampling or airborne thermal imagery. Please see Wang et al. (2008) and Wang (2005) Master's Thesis for more detail.
