Project Owner: Slovenian Geological Survey Project Phases: -) Field work and sampling (either from drill core or from outcrop) -) physical preparation -) Extraction of cosmogenically produced Al and Be from 10 samples collected in Slovenji Gradec basin -) age calculation, reporting The aim of this project is the investigation of sediments in the basin filling of the Sloveni Gradec basin, in particular, the attempt to determine the depositional period of the sediments. For this purpose, 4 boreholes are drilled by the project partner (Geological Survey of Slovenia), which recover sediments from the deeper parts of the basin. The sedimentological record by the project partner will be complemented and numerically constrained by an age model from the Laboratory for Cosmogenic Nuclide Extrusion (laboratory homepage:; IAG, BOKU). If carried out successfully and with suitable sediments, tectonic activity in the Sloveni Gradec basin can be calculated. This information will be further used for the risk assessment of the Krsko nuclear power plant. Translated with (free version)

To better understand Patagonian glacier-climate relationships it is necessary to reconstruct the former glacier fluctuations. The Northern (NPI) and Southern (SPI) Patagonian Icefields have been the subject of many intensive studies. Comparatively, very few records exist for the glaciers of the southernmost Cordillera Darwin icefield (CDI). The reason for this lack of southernmost records is largely related to the fjord- terminating nature of the glaciers, which results in limited terrestrial evidence of glacier variability. However, the evidence for the timing and extent of the CDI glaciers during the last glacial – interglacial transition (LGIT) has produced a paradox of conflicting evidence for either a ‘larger’ ice field and associated ice dammed pro-glacial lakes or a ‘smaller’ ice field with implications for rapid glacier retreat. The aim of this project is to determine the extent and timing of glacial fluctuations in the southern Estrecho de Magallanes and Fuegian archipelago at the end of the last ice age (c. 18,000 to 10,000 years before present (18-10 ka)) to resolve this enduring paradox and to advance our understanding of the nature and timing of climate changes during the LGIT. The past extent of the CDI and associated proglacial lakes and meltwater routes has important implications for our understanding of geomorphic barriers to the dispersal of early humans in this region

There is an urgency to study the large paleo sand dunes of coastal central semiarid Chile (31-35 ºS) and their forming factors because they can provide key insights into past and present mechanisms of environmental change and provide answers to questions, such as how present climate change and linked glacier retreat in the Andes can affect dunes and associated ecosystems. The paucity of data available and limited evidence within this extensive semiarid region, including the Andes and coastal regions, do not allow for the development at present for a definitive conceptual model of dune formation and the potential causal role of the Andean glaciers as drivers of coastal eolian morphogenesis. In this project, we plan to assess the role of the Andean glacier change as a causal factor driving the coastal sand dune formation, extent and variability in central semiarid Chile (30-35ºS) during the last glacial cycle. Our study rationale considers the Andean river discharge linked to climate and glacier fluctuations as driving the “on” and “off” switch of sediment supply for coastal eolian deposits at different temporal scales. In order to determine the Andean glacier and coastal dunes geographic and causal linkages, we will build precise in situ moraine based 10Be - 36Cl, and ancient dune-based luminescence chronologies for the last glacial cycle to be able to detrmine how the enhanced sediment supply from the Andes to the coast linked to glacier fluctuations and pervasive paraglacial processes is connect with coastal paleo sand dune development. The expected results of this project will impact and significantly increase our knowledge regarding large sand coastal sand dunes origin and change in time; timing of glaciation and deglaciation in the semiarid Andes; mechanisms of climate change acting on central Chile during the late Quaternary; and mountain geomorphic process linked to glacial and deglacial phases, such as the present one.
