Last deglacial sea-surface temperature evolution in the Southeast
Pacific compared to climate changes on the South American continent.
Quaternary Science Reviews, Vol. 21, pp. 2085-2097.
Applying the alkenone method, we estimated sea-surface temperatures
(SSTs) for the past 33 kyr in two marine sediment cores recovered
from the continental slope off mid-latitude Chile. The SST record
shows an increase of 6.7°C from the last ice age (LIA) to the
Holocene climatic optimum, while the temperature contrast between
LIA and modern temperatures is only about 3.4°C. The timing and
magnitude of the last deglacial warming in the ocean correspond
to those observed in South American continental records.
According to our SST record, the existence of a Younger Dryas
equivalent cooling in the Southeast Pacific is much more uncertain
than for the continental climate changes. A warming step of about
2.5°C observed between 8 and 7.5 cal kyr BP may have been linked
to the early to mid-Holocene climatic transition (8.2–7.8 cal kyr BP),
also described from equatorial Africa and Antarctica. In principal,
variations in the latitudinal position of the Southern Pacific
Westerlies are considered to be responsible for SST changes
in the Peru-Chile current off mid-latitude Chile.
STUDY NOTES: Alkenone sea-surface temperature (SST) estimates for
the past 33 kyr from two sediment cores collected
from the continental slope off mid-latitude Chile.
