Abstract

The use of unoccupied aerial vehicles (UAVs) in the study of submarine groundwater discharge (SGD) zones has been shown to be useful and timely, however, to do so has shown to be costly. The purpose of this thesis is to evaluate the effectiveness of a lower-budget UAV to represent water surface temperatures accurately. Using the Parrot ANAFI UAV with a FLIR camera, flights were conducted during low tides due to decreased water column depth, higher visibility, and lower wave action. After each flight, an analysis performance to reevaluate the outcomes and adjust parameters for viable outcomes is conducted; there were two study sites with different characterizations to compare the same parameters. A location with less turbidity, water column disruption, and higher amounts of key points produced more accurate outcomes. To effectively create accurate outcomes, a camera with RJPEG capabilities is needed; these cameras cost a minimum of $3,500 alone. Although this study showed potential, the lower budget UAVs require strict parameters limiting the study sites.
