Our multidisciplinary group promotes the reconstruction of environmental and climate changes, their causes, and dynamic interactions through the multiproxy characterization of the geologic record. Throughout the history of our planet, the geological processes in general and climate change in particular have fingerprinted the sedimentary record. Furthermore, the increasing anthropogenic influence in the recent past is also readily identifiable in this geological record.
This research is carried out using a multiproxy approach and focuses on lake sedimentology and global change, impact of geological and anthropogenic processes on the natural geochemical balances, sedimentary processes and biomineralization, geochronological dating and physical and magnetic properties of the sediments as indicators of environmental and climatic processes.
The objective of the research group is the robust and accurate reconstruction of past climate oscillations and environmental fluctuations as well as identify short, medium and long term trends of these changes through the multiproxy characterization of the geological sedimentary record. These reconstructions provide valuable data to put into a broad temporal perspective the current climate and environmental trends as well as they provide useful insights about which has been the historical and current anthropogenic role in the recent evolution of the Earth. These climatic and environmental reconstructions also provide data that allows the establishment of possible future climatic and environmental scenarios.
To achieve this goal the group is developing the following research lines:
- reconstruction of climatic and environmental changes using a high temporal resolution multiproxy approach of lacustrine sedimentary records;
- determining the geochemical impact of large-scale geological processes (e.g., explosive volcanic eruptions or floods);
- evaluating the relationships between processes and sedimentary environments and biomineralization, and
- characterizing physical and magnetic properties of the sedimentary record as proxies of climatic and environmental events.
