Potrok Aike Maar Lake Sediment Archive Drilling Project
Project Acronym: PASADO | State: Completed | Expedition ID: 5022
The research initiative "Potrok Aike Maar Lake Sediment Archive Drilling Project" (PASADO) within the framework of ICDP addresses several key issues:
- The evolution of maar craters,
- Quantitative climatic and environmental reconstruction,
- Fire history,
- Tephra and dust deposition
- Palaeosecular variation of the Earth's magnetic field for the last several glacial to interglacial cycles.
Moreover, dust and tephra records provide links to marine sediment archives and ice cores. Obtained reconstructions of climate variability have been compared to climate simulations from Global Circulation Models, to detect signals of climatic forcing.
