Abstract

Unmanned aerial vehicles (UAS) excel in providing rapid, temporary access with minimal environmental disturbance. They are particularly well-suited to remote sensing tasks where observations are made quickly and from a distance. Many of the sensors that are required to localize remotely-sensed data are included in the flight vehicle. A large amount of information can therefore be synthesized after a relatively short time spent in the field. However, planning is still critical when using UAS to collect scientific quality data. To assess the feasibility of monitoring water quality parameters, several UAS flights were performed over portions of the Maumee River during a significant harmful algal bloom event in September and October 2017. The UAS were integrated with cutting edge miniaturized spectroradiometers providing hyperspectral reflectance measurements of the water. Several documented water quality retrieval algorithms were applied to the measured spectra providing estimates of in water parameters. UAS Reflectance and algorithm estimates were then compared with coincident on ground measurements to verify their applicability.
