Summary

Abstract: ENGLISH:

The ice masses of the Antarctic Peninsula have been subject to significant changes during the recent decades, with the dramatic disintegration of sections of the Larsen Ice Shelf and the drastic reduction in the extent and volume of glaciers. There is clear evidence of considerable glacier retreat on Hielo Patagónico Sur, southern Patagonia. The changes in the Antarctic Peninsula are ... associated with the pronounced regional atmospheric warming, which is expected to be detected also in the region of the Patagonian glaciers. A proper assessment of the impact of these changes to the environment is seriously affected by the lack of basic glaciological data from long term monitoring programmes. The aim of the project is to monitor climatic change in both regions and to assess its impact on glaciers in areas considered in this study, to investigate the calving processes, and to improve the knowledge of the impact of the removal of ice shelves on the dynamics of tributary glaciers. Collection of glaciological, meteorological, limnological, and paleoclimatic data will continue for study of ice-climate interactions. The systematic monitoring of glacial areas will be complemented by remote sensing. The project is in part the continuation of previous studies which will provide a valuable glacioclimatic database for both regions.

SPANISH:

Las masas de hielo en península Antártica sufrieron cambios muy significativos durante décadas recientes, como la dramática desintegración de sectores de Barrera de Hielo Larsen y la drástica reducción en extensión y volumen de los glaciares. Existen claras evidencias del notorio retroceso glaciar en Hielo Patagónico Sur, Patagonia Austral. Los cambios en península Antártica están asociados al pronunciado calentamiento atmosférico y se intentará detectar la existencia del mismo en la region de glaciares Patagónicos. Una correcta evaluación del impacto de estos cambios en medioambiente está seriamente afectada por falta de datos glaciológicos básicos, que resultan de programas de monitoreo a largo plazo. El objetivo del proyecto es monitorear el cambio climático en ambas regiones y evaluar el impacto del mismo en glaciares de zonas consideradas en este estudio, investigar los procesos de desprendimiento, y mejorar el conocimiento del impacto producido por remoción de barreras de hielo en la dinámica de sus glaciares tributarios. Se continuará recolectando datos glaciológicos, meteorológicos, limnológicos y paleoclimáticos para estudios de interacción hielo-clima. El monitoreo sistemático de zonas englazadas se complementará con sensores remotos. El proyecto es continuación parcial de estudios anteriores que permiten contar con una valiosa base de datos glacio-climáticos de ambas regiones.
