Achim A. Beylich is a geomorphologist with 26 years of work experience in field- and laboratory-based process geomorphic research in various climatic environments and landscapes in Iceland, Sweden, Finland, Canada, Russia, Germany, Austria, Norway and Spain. Since 2004 he has initiated and led a number of international and interdisciplinary research groups, networks and programs on geomorphologic earth surface processes and landscape development under ongoing or accelerated climate change and increasing anthropogenic pressures. He has over 100 scientific publications in journals and books, and numerous edited works. He is Editor-in-Chief for the Geomorphology journal (Elsevier) and an Editorial Board Member for several international scientific journals. He is currently Chair of the IAG Working Group DENUCHANGE and of the Geomorphological Research Group of Norway (IAG GeoNor), and initiator and Chair of the Nordic Network of Geomorphology Groups from Norway, Sweden, Finland, Denmark and Iceland (IAG GeoNorth). Daniel Vázquez Tarrío holds a PhD in Geology from the University of Oviedo and currently works as Assistant Lecturer at the Polytechnic University of Madrid. He is a fluvial geomorphologist specialized in the study of river hydraulics, sediment transport and morphodynamics of gravel-bed rivers. His approach to these questions involves coupling the field monitoring of these processes with the computation and modelling of water and sediment flows. He has also worked extensively on the impact of human interventions (dams and embankments) and land-use changes on sediment balances and flood-hazards in river systems. Daniel Vázquez Tarrío has investigated in these topics within the framework of several research projects focused in many rivers from Spain and France. Dr. Dongfeng Li is a Research Fellow at the Geography Department of National University of Singapore. He is broadly interested in climate change, glaciers, permafrost, rivers, sediment transport, and hydropower dams. His current research focuses on sediment transport processes within the Earth’s cold environments, specifically driven by atmospheric, cryospheric, and hydrologic processes using remote sensing data and techniques, in-situ and field measurements, and numerical modeling approaches. During his PhD, he for the first time assessed the impacts of modern climate change on fluvial sediment fluxes in High Mountain Asia, for which he was awarded the IPCC Scholarship Award. He is also the co-founder of the Chinese Geomorphology Club for early-career scientists and a core-member of the DENUCHANGE working group under the International Association of Geomorphologists Marc Oliva holds a PhD in Geography from the Universitat de Barcelona, where he works now as research scientist and leads a research group on Antarctic, Arctic and Alpine Environments. He has carried out research and teaching activities in universities of Portugal, Canada, Switzerland, Spain and Russia. He has participated in eight expeditions to Antarctica and four to the High Arctic. Apart from the Polar Regions, he has also conducted research in other mountain regions (Rocky Mountains, Alps, N Iceland, Pamir, Tien Shan, Pyrenees, and Cantabrian Mountains), which has provided him a wide comprehension of Earth surface processes in cold-climate environments. His research interests include the study of geomorphological processes and past environments and climate in the Polar Regions and high mountains using a wide range of natural records (glacial, periglacial, and lacustrine). Mario Morellón Marteles is a lecturer in Geology at the Complutense University of Madrid, Spain. His research has been focused on the reconstruction of past environmental changes based on the multidisciplinary analysis of lake sediments from key areas (Mediterranean Basin, South America, and Tibet) influenced by the main modes of climate variability (North Atlantic Oscillation, ENSO, and Indian Summer Moonson) and/or different human impacts, from the late Pleistocene to the Anthropocene. His approach is based on sedimentological and geochemical proxies but integrates biological indicators as well. During his career in Spain, United Kingdom and Switzerland, M. Morellón has led and participated in projects and scientific initiatives aimed to disentangle the relative contributions of human activities and climate variability on recent environmental change, integrating different natural archives and proxies.
