Source-to-Sink-Fluxes in Undisturbed Cold Environments

About this book

Amplified climate change and ecological sensitivity of polar and cold climate environments are key global environment issues. Understanding how projected climate change will alter surface environments in these regions is only possible when present day source-to-sink fluxes can be quantified. Source-to-Sink-Fluxes in Undisturbed Cold Environments provides the first global synthesis and integrated analysis of environmental drivers and quantitative rates of solute and sedimentary fluxes in cold environments, and the likely impact of projected climate change. The focus on largely undisturbed cold environments allows ongoing climate change effects to be detected and, moreover, distinguished from anthropogenic impacts. A novel approach for co-ordinated and integrative process geomorphic research is introduced to enable better comparison between studies. This highly topical and multidisciplinary book, which includes case studies covering Arctic, Antarctic, and alpine environments, will be of interest to graduate students and researchers in the fields of geomorphology, sedimentology and global environmental change.

Biography

Achim A. Beylich is a senior research scientist at the Geological Survey of Norway, Trondheim. He has also held an Associate Professor position at the Norwegian University of Science and Technology (NTNU) in Trondheim. Dr Beylich has more than 20 years of experience in field- and laboratory-based quantitative process geomorphic research in cold climate environments, in Iceland, Sweden, Finland, Norway, Canada, Russia, and the German Alps. He initiated the SEDIBUD (Sediment Budgets in Cold Environments) working group of the International Association of Geomorphologists (IAG), which he has chaired and led since 2005.

John C. Dixon is Professor of Geosciences at the University of Arkansas, USA. His principal research interests lie in the area of landscape evolution in cold and warm dry climates, and in particular, the role of chemical processes in soil and regolith formation. Professor Dixon has worked in Swedish Lapland, Alaska, the Rocky Mountains, southern Australia and southern Norway, and has published over 100 refereed journal articles and book chapters.

Zbigniew Zwoliński is a Professor at the Institute of Geoecology and Geoinformation at Adam Mickiewicz University, Poland. His main research interests include fluvial geomorphology and sedimentology, GIScience, geodiversity and global changes. He conducts research on desert landforms as well as landforms in tropical and polar regions, and has participated in many summer expeditions to the High Arctic (Spitsbergen, Iceland) and Antarctica (King George Island).
