Interactions between coastal waters and marine-terminating glaciers in the Polar Regions play a significant role in global sea level rise fueled by a rapidly warming Arctic. However, few oceanographic measurements exist near glacier termini and in inner fjord systems with severe ice mélange. We present a cost-efficient (€ 5700) uncrewed aerial vehicle (UAV) with an on-board autonomous winch system that allows oceanographic profiling in remote, hazardous areas using a commercial conductivity, temperature, and depth (CTD) sensor payload. The UAV is based on a commercial kit helicopter, allowing for high-speed and efficient cruise flight along with easy logistical handling and deployment. An open-source autopilot system is used to provide pilot assistance and autonomous flight capabilities. The total takeoff weight of the UAV including payload is 6.5 kg with a hover endurance of 24 minutes and a range of 6 km. Testing of the system was conducted in South Greenland during winter conditions in March 2023 with ...
