En los últimos años se ha asentado en la comunidad científica y política internacional el paradigma conceptual que el pasado constituye la clave para comprender los posibles escenarios climáticos y ecosistémicos futuros. El análisis de momentos de rápido cambio en el pasado provee la información requerida para determinar como responderán los sistemas a los cambios futuros. Debido a la gran diferencia en el desarrollo de estudios paleoclimáticos entre los Hemisferios Norte y Sur, los estudios del pasado provenientes de la Región de Magallanes y Antártica son relevantes no tan sólo a escala local/regional sino que también a nivel hemisférico y global. Registros detallados provenientes del Hemisferio Sur son indispensables para entender la globalidad del fenómeno paleoclimático, determinar sus causas y consecuencias.

Consequently, the study of the environmental variability in the Fire region Patagonia and Antarctica in temporary scales of short and long term has an undeniable practical interest: How it will be the climate in the next decades and which will be their socio-economic and environmental impacts in our region? The answer to these questions can have important consequences for the planning of the productive activities, of infrastructure and development of Magallanes.

The study of the climatic variability based on instrumental series severely is limited by the temporary extension of these registries. Therefore, it turns out from great interest to resort to indicators or environmental archives (registries proxy) that can provide climatic registries with hi-res, sufficiently long, as to be able to characterize in appropriate form the natural climatic variability of a region. In our line of investigation we are raising to investigate like environmental indicators fossil pollen, the ring of trees and the recent variations of glaciers.

Objectives of line

• To reconstruct the happened paleoambientales changes during postglacial in the Fire ecosystems Patagonia and Antarctica through combined use of indicators such as fossil pollen, sediments, tefras and isotopes.
• To reconstruct environmental variations in ecosystems the terrestrial Patagonia Fire being used the answer of series of ring of trees to the climatic changes (dendroclimatology), the dated one of the glacier fluctuations (dendroglaciology), and the study of dynamic the ecological ones of the subAntarctic forests (dendroecology).
• To determine on local and regional scale the answers of the masses of Fire ice Patagonia and Antartica to the climatic variations of the last decades, using remote methods of observation in land and sensors.
• To generate data bases space that allow to represent the environmental paleo information and to represent/to model studied dynamic processes.
• To apply modifications of the technology of systems of radar used in measurements of thickness of ice for other aims of investigation or productive .
