Since then, these meetings have been an excellent opportunity for integrating the polar community, exchanging experiences, and a discussion between Polish and international polar researchers representing various scientific disciplines. The Polar Symposium is currently co-organised by the Committee of Polar Research, Polish Academy of Sciences, and the Polish Polar Consortium, and until recently it has also been co-organised by the Polar Club of the Polish Geographical Society. Instead, during the 40th International Polar Symposium, a new Polish Polar Club will debut as an independent association, thus continuing the functioning of the Club since 1974. 2025-10-20T00:00:00Z https://dspace.igf.edu.pl/xmlui/handle/123456789/140 Results of Geomagnetic Observations - Belsk, Hel, Hornsund, 2024 Reda, Jan; Neska, Mariusz; Wójcik, Stanisław; Czubak, Paweł 2025-09-12T00:00:00Z https://dspace.igf.edu.pl/xmlui/handle/123456789/139 Remote sensing as a support tool to map suspended sediment concentration over extended river reaches Nones, Michael; Guo, Chao Spatiotemporal variations of sediments transported along rivers play a crucial role in a wide spectrum of uses, such as navigation, recreation, habitats or river environmental protection. The advancement in technology has made it possible to use various indirect techniques to study and evaluate the transport of suspended sediment in fluvial environments. To investigate large-scale phenomena, remote sensing is becoming a largely utilized approach, as it allows to combine spatially distributed and local information. The systematic change of suspended sediment concentration (SSC) and dynamic processes controlling sediment transport at a given local scale are often not well known, and generally investigated using reach-specific field information. In this work, SSC maps were created by combining satellite images with local monitoring in situ SSC data, using the Zhijiang-Chenglingji reach of the Changjiang River (China) as a case study, and analyzing how SSC dynamics changed over the period 2016–2023, considering both low- and high-flow events. Multiple relationships between measured SSC and reflectance were selected from the literature and tested. Results show that a combination of Sentinel-2 bands 3,4, and 5 represents the best-performing statistical model (R2 = 0.73) in mapping SSC spatiotemporal variations over an extent of dozens of kilometers. Despite the uncertainties connected to the small amount of data available and the differences between SSC data measured over the vertical and surface reflectance, this application shows the potential of remote sensing in mapping SSC at a large spatial scale, overcoming the limitations of localized field sampling, eventually suggesting a relatively simple approach that could assist water managers in mapping large-scale dynamics of SSC for applications such as navigation, habitat preservation, and hydropower production. 2025-07-01T00:00:00Z https://dspace.igf.edu.pl/xmlui/handle/123456789/138 BOOK OF ABSTRACTS. XLII International School of Hydraulics FRESHWATER SYSTEM HEALTH: A HYDRAULIC PERSPECTIVE. Radocza, Poland, 20–23 May 2025 Kalinowska, Monika; Mrokowska, Magdalena; Rowiński, Paweł M. The 42nd International School of Hydraulics, titled “Freshwater System Health: A Hydraulic Perspective”, held on May 20–23, 2025, in Radocza near Kraków, continued a series of events focused on broadly understood hydraulics. The conference covered the fundamentals of hydraulics in the context of understanding and managing the health of rivers, lakes, and other aquatic ecosystems. It highlighted new and challenging topics in both applied and basic research. ISH2025 aimed to foster a fruitful exchange of knowledge, ideas, and experiences in various fields of hydro-environment research. It also served as a platform for intellectual growth, collaboration, and innovation, helping to build new connections and strengthen existing ones. ISH2025 sought not only to provide answers and explore new ideas, but also to offer a global forum for scholars, decision-makers, and enterprises sharing a common interest in the field. 2025-05-19T00:00:00Z
