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.

First PASADO Quebec workshop
Eleven participants from Quebec City, Rimouski and Montreal met in Quebec City for the first PASADO Quebec workshop. PhD students and postdocs showed their first results.
Hurray and three cheers for the sampling crew!
Today the last set of samples was recovered from the 107 m long PASADO composite profile. During this enormous effort a total of 35,217 individual samples was secured, labeled and stored away.
The very last day of PASADO field work
While all containers have been packed and are ready to be picked up by trucks, today the dismantling of Potrok City started while the last scientists and the kitchen team left.
