Late Holocene sea-surface temperature and precipitation
variability in northern Patagonia, Chile (Jacaf Fjord, 44°S).
Quaternary Research, Vol. 72, Issue 3, pp. 400-409,
November 2009.

A high-resolution multi-proxy study including the elemental and
isotopic composition of bulk organic matter, land plant-derived
biomarkers, and alkenone-based sea-surface temperature (SST)
from a marine sedimentary record obtained from the Jacaf Fjord
in northern Chilean Patagonia (~44°20'S) provided a detailed
reconstruction of continental runoff, precipitation, and summer
SST spanning the last 1750 yr. We observed two different regimes
of climate variability in our record: a relatively dry/warm period
before 900 cal yr BP (lower runoff and average SST 1°C warmer
than present day) and a wet/cold period after 750 cal yr BP
(higher runoff and average SST 1°C colder than present day).
Relatively colder SSTs were found during 750-600 and 450-250
cal yr BP, where the latter period roughly corresponds to the
interval defined for the Little Ice Age (LIA). Similar climatic
swings have been observed previously in continental and marine
archives of the last two millennia from central and southern Chile,
suggesting a strong latitudinal sensitivity to changes in the
Southern Westerly Winds, the main source of precipitation in
southern Chile, and validating the regional nature of the LIA.
Our results reveal the importance of the Chilean fjord system
for recording climate changes of regional and global significance.
STUDY NOTES: High-resolution multi-proxy fjord marine sediment data
for the last 1750 years from northern Chilean Patagonia.
Data include the elemental and isotopic composition
of bulk organic matter, land plant-derived biomarkers,
and alkenone-based sea-surface temperature (SST).
These data provide a history of continental runoff,
precipitation, and summer SST spanning the last 1750 yr.
