Marc Oliva holds a Ph.D. in Geography from the Universitat de Barcelona, where he leads a research group on Antarctic, Arctic, and Alpine Environments. 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, Cantabrian Mountains), which have 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, lacustrine). Daniel Nývlt holds a Ph.D. in Physical geography from the Charles University in Prague. He currently works as Associate Professor at the Department of Geography, Masaryk University in Brno, where he is the Head of the Czech Antarctic Research Programme and the Polar-Geo-Lab. He has scientifically worked at five continents, but focuses principally on Polar and Alpine environments. He has participated or led eleven expeditions to Antarctica and seven expeditions to the High Arctic (Svalbard, Greenland). His research interest covers wide range of geoscientific disciplines of Quaternary Geology and Physical Geography from sedimentology, glacial geology, permafrost science, geomorphology, paleoclimatology, through stratigraphy, and glaciology toward ecology, geochronology, natural hazards, and remote sensing.José M. Fernández-Fernández holds a Ph.D. in Geography from the Universidad Complutense de Madrid, where he is currently Assistant Professor and member of the High Mountain Physical Geography research group. He has done fieldwork in several mountains of Iceland (Tröllaskagi Peninsula), the Iberian Peninsula (Iberian Range, Central Range, NW Ranges, Cantabrian Mountains, and Pyrenees) and Antarctica (South Shetland Islands). His research is focused on the glacial evolution at different time scales, the origin and dynamics of rock glaciers and debris-covered glaciers, and the application of surface exposure dating and geographic information systems to achieve palaeoenvironmental reconstructions.
