STUDY OF GLACIO-CLIMATIC CHANGES, PERMAFROST AND HYDROGEOLOGY ON NORTHERN ANTARCTIC PENINSULA REGION
Listed in NASA Earthdata CMR
ENGLISH The cryosphere of the Antarctic Peninsula was subject to major changes in recent decades, with a drastic reduction in the extent and volume of glaciers, a decrease of ice-rich permafrost areas, and changes in hydrological and hydrogeological environments.
Description
These changes are associated to a pronounced regional atmospheric warming recorded on the Antarctic Peninsula. The aim of the project is to continue monitoring changes in areas of research.
Glacio-climatic conditions and their relationship with permafrost, surface and underground waters in different regions of Antarctic Peninsula, James Ross Island group and isla 25 de Mayo will be assessed, to determine the impact of regional climate changes on periglacial environment. Glaciological, meteorological, geocryological, hydrogeological and paleoclimate data will be analyzed in detail to establish the climate-cryosphere interaction.

A systematic environmental monitoring will be complemented with application of remote sensing. This will allow to develop a climate-cryosphere coupling model to be used as a tool to predict the climatic variability and its environmental consequences on Antarctic Peninsula. The project is partly a continuation of earlier works carried out by the Glaciology Division of Instituto Antartico Argentino, providing a valuable data base of glacio-climatic, geocryologic and hydrogeologic information of the regions to be studied.
SPANISH La criosfera de la peninsula Antartica sufriograndes cambios en las decadas recientes, entre otros una drastica reduccion en la extension y el volumen de los glaciares, disminucion de las areas de permafrost rico en hielo y la modificacion de ambientes hidrogeologicos e hidrologicos. Estos cambios estan asociados a un consistente y pronunciado calentamiento atmosferico regional de la peninsula Antartica. El objetivo del proyecto es continuar monitoreando los cambios en las areas investigadas.
Se evaluaran las condiciones glacio-climaticas y su relacion con el permafrost, con las aguas superficiales y subterraneas en distintos sectores de la peninsula Antartica, el grupo insular James Ross e isla 25 de Mayo, a fin de determinar el impacto del cambio climatico regional en el medio ambiente periglacial. Se analizaran en detalle los datos glaciologicos, meteorologicos, geocriologicos, hidrogeologicos y paleoclimaticos a fin de establecer la interaccion clima-criosfera.
El monitoreo sistematico ambiental se complementara con la aplicacion de sensores remotos. Todo ello permitira desarrollar un modelo de acople clima-crioesfera, que podra ser utilizado como una herramienta predictiva de la variabilidad climatica y sus consecuencias medio-ambientales en la peninsula Antartica. Este proyecto es continuacion parcial de trabajos anteriores realizados por la Division Glaciologia del Instituto Antartico Argentino, que proveen una valiosa base de datos glacio-climaticos, geocriologicos e hidrogeologicos de las regiones a estudiar.
