摘要：Patagonia is subjected to shifts in polar
and mid-latitude winds, pressure
fi elds and precipitation regimes, as
well as to variations related to El Ni.o
Southern Oscillation (ENSO) and
the Antarctic Oscillation (AO). Therefore,
environmental and climatic reconstructions
have the potential to
provide unique records of variations
in the hydrological cycle, changes in
aeolian dust deposition, and consequences
and frequencies of volcanic
activities. Since 2001, crater lakes of
the Pali Aike Volcanic Field (southernmost
Patagonia, Argentina) have
been studied in the framework of
the interdisciplinary project “South
American Lake Sediment Archives
and Modelling” (SALSA) funded by
the German Climate Research Program
(DEKLIM) and carried out in
close cooperation with Argentine
scientists (PAGES News 12/2, 9-11).
