Surveyance of the marine environment for beached plastic debris using a novel, hyperspectral shortwave infrared camera on an uncrewed aerial vehicle (UAV)
… of shoreline plastic litter with the aerial deployment of a specialised, hyperspectral<br/>camera that is sensitive to shortwave infrared (SWIR) light and that measures signal from<br/>more than ten times as many wavelengths as a conventional digital camera. The rationale<br/>for …

Application of Remote Sensing Techniques for the Study of Neotectonic Deformation, Subsidence and Coastal Processes
… and their beach-dune systems. I conducted an uncrewed aerial vehicle (UAV) survey at these two sites and collected sediment samples for grain size analysis. Using the UAV data, I quantified the change in terms of elevation, sediment volume, and vegetation cover and performed a risk assessment …

Active Faulting in the Northern Walker Lane and Post-Earthquake Reconnaissance in the Central Walker Lane, Nevada and Eastern California
… in the trench. For the Bonham Ranch fault, Uncrewed Aerial Vehicle (UAV) flight surveys were conducted in three locations to investigate differences between topographic scarps formed by tectonic displacement and shoreline processes. Cross cutting relations between the different scarp types …

Evaluating UAV Visual-Inertial Odometry Trajectory Error and Feature-Level Metrics over Repetitive Floor Patterns
… is a widely used state estimation technique for Uncrewed Aerial Vehicle (UAV) navigation in environments where Global Navigation Satellite System (GNSS) signals are unavailable. VIO systems that rely on visual feature tracking are susceptible to performance degradation when operating over …

Beyond Visual Line of Sight Drone Simulator with User-defined Risk Layers
… become increasingly prevalent across a range of UAV applications, the need for reliable tools to support safe mission planning and dynamic risk assessment is growing. This work introduces a web-based simulation framework for BVLOS flight planning and validation, developed as a full-stack Flask …

UAV-based investigations into the hydrology and dynamics of the Greenland Ice Sheet
… This thesis investigates the potential of Uncrewed Aerial Vehicles (UAVs) to provide intermediate-level observations of the interactions between ice sheet hydrology and dynamics at a fast-flowing, marine terminating glacier in West Greenland. I first describe the development of a low- cost …
