Resumen

The use of multi-proxy lake records to reconstruct Holocene environmental changes of marginal part of Antarctica, Daniel Nývlt

The James Ross Island archipelago bear one of the largest ice-free area at the northern tip of Antarctic Peninsula, where different types of lakes evolved after the deglaciation. Deglaciation of the area started approximately at 12.9 ka and the oldest lakes on low-lying areas originated therefore during the Pleistocene/Holocene transition. However, neoglacial advance of local glaciers from the Mid- and Late- Holocene times are also known and numerous lakes evolved after the retreats of these neoglacial advances and are therefore few thousands, or even only few hundreds years old. Multi-proxy records covering various physical, chemical and biological data help to reconstruct past environmental and climatic changes in lake catchments of this marginal part of Antarctica. Best records from this are originates from Monolith Lake on James Ross Island, Esmeralda Lake on Vega Island; Beak 2 Lake on Beak Island, or Boeckella Lake in Hope Bay, Antarctic Peninsula. The lecture will present results of international research activities (mainly Argentinean-Czech collaboration) to reconstruct part environmental conditions and to compare lake records with ice-core records at the northernmost Antarctic Peninsula and with other lake records in Antarctica.

Assoc. Prof. Daniel Nývlt, PhD. (*1976), graduated from the Charles University, Prague in 1999 and completed Ph.D. in 2008 at the Department of Physical Geography and Geoecology, Charles University in Prague, for which he has been awarded the “Dean’s Prize” of Faculty of Science, Charles University in Prague for the best Ph.D. thesis. He received Associate Professorship for Physical Geography at the same faculty in 2015. He has worked for the Czech Geological Survey since 1998 as a Quaternary specialist, Head of Section or Deputy director of Brno branch and is based as Associate Professor at the Department of Geography, Masaryk University now. He has experience with geomorphological and geological research at five continents (Europe, Asia, Northern and Southern America, the Arctic and Antarctica), joined 13 research expeditions to Antarctica, Svalbard and Greenland, frequently publishes results in international journals and books and is a co-author of numerous geological and geomorphological maps and provides reviews for international scientific journals. His research is focused on a wide range of scientific disciplines of Quaternary Geology and Physical Geography from sedimentology, palaeoclimatology, glacial geology, geomorphology, through stratigraphy and glaciology towards geochronology, ecology, natural hazards and remote sensing. He gives advance courses on Quaternary Geology and Palaeogeography; Geomorphology; Glaciers of the Earth and Physical Geography and Ecology of Polar Regions at the Faculty of Science, Masaryk University in Brno, the Faculty of Science, Charles University in Prague and the Faculty of Science, University of South Bohemia in České Budějovice. He is Co-editor of Bulletin of Geosciences and member of editorial boards of the Journal of Geological Sciences – Anthropozoic and Czech Polar Reports. He is the head of the Czech Subcommision on Quaternary Stratigraphy and voting member of the Czech Commission on Stratigraphy and the Czech co-delegate to the Commission on Environmental Protection of the Antarctic Treaty System. D. Nývlt cooperates with researchers from France, UK, Argentina, Norway, Germany, Poland, Russia, or Portugal. He is an author or co-author of nearly 100 reviewed scientific articles or book chapters with 22 of them being WOS-listed; times cited: 174; h-index: 9.
