Potrok Aike Maar Lake Sediment Archive Drilling Project

Abstract

This 4th International PASADO Workshop is related to the research initiative “Potrok Aike Lake Sediment Archive Drilling Project” (PASADO) within the framework of the “International Continental Scientific Drilling Programme” (ICDP). PASADO addresses challenging issues of geoscientific and socioeconomic relevance related to Earth history and climate like qualitative and quantitative climatic and environmental reconstruction as well as reconstruction of the palaeosecular variation of the Earth's magnetic field but also natural hazards like fire history, frequency of volcanic activity including tephra fallout and dust deposition. The history of volcanic activities for the last ca. 50,000 years is another interesting topic. Moreover, dust and tephra records provide links of this unique southern hemispheric terrestrial record to marine sediment archives and to ice cores from Antarctica. Finally, obtained reconstructions of climate variability will be compared statistically with the output of Global Circulation Model (GCM) simulations to improve our understanding of forcing mechanisms of the global climate.
