The High Arctic region is experiencing rapid climate changes, with rising temperatures impacting one of the most fragile environments on the planet. This study employs Uncrewed Aerial Vehicle (UAV) technology equipped with Zenmuse H20T thermal camera to investigate the spatio-temporal variations of ground and water temperatures in the catchments of Southwest Spitsbergen. The UAV-based thermal imaging provides high-resolution and real-time data, allowing for a comprehensive understanding of temperature dynamics in this remote and challenging environment. The integration of UAV technology and in-situ measurements facilitates the collection of data at unprecedented spatial and temporal scales, allowing for a more detailed analysis of temperature trends and patterns.The study focuses on assessing ground temperature variations across different land cover types to discern the influence of seasonal variations on these components. Moreover, this study extends its scrutiny to the thermal patterns of Arctic hydrological systems, encompassing channels and ponds. This multidimensional approach enables the identification of flow paths in the catchments, including groundwater intrusion and surface mixing. The study aims to contribute valuable insights into the complex interplay between cryo-, hydro-, and meteorological dynamics in the High Arctic.The study was carried out with the SONATA BIS project financed by the Polish National Science Centre (grant no. 2020/38/E/ST10/00139).Keywords: UAV, Zenmuse H20T, Land Surface Temperature, Hornsund, Spitsbergen
