Over the last decade, an increasingly number of tropical and subtropical ice cores has been extracted along the Andes of
South America between 0° and 30°S. At higher latitudes, numerous ice core studies have been completed, especially
in the Antarctic Peninsula. In order to close the gap between subtropical and polar environment in this unique 8000km long
meridional transect of ice core records, we are initiating a new deep ice coring program in the Northern Patagonian Icefield
(Chile) in order to explore the tropical-extratropical teleconnexions. Two potential sites were explored in April 2005 by the
Research Unit Great Ice (IRD) in collaboration with the centro de Estudio Cientifico (Chile). We present here the first
results from San Valentin summit survey (3900m, 47°S), and chemical/isotopic records from a 16m shallow ice core.
