Pronounced interannual variability in tropical South Pacific
temperatures during Heinrich Stadial 1.
Nature Communications, 3, Article 965.

The early last glacial termination was characterized by intense
North Atlantic cooling and weak overturning circulation. This
interval between ~18,000 and 14,600 years ago, known as Heinrich
Stadial 1, was accompanied by a disruption of global climate
and has been suggested as a key factor for the termination.
However, the response of interannual climate variability in
the tropical Pacific (El Niño-Southern Oscillation) to Heinrich
Stadial 1 is poorly understood. Here we use Sr/Ca in a fossil
Tahiti coral to reconstruct tropical South Pacific sea surface
temperature around 15,000 years ago at monthly resolution.
Unlike today, interannual South Pacific sea surface temperature
variability at typical El Niño-Southern Oscillation periods was
pronounced at Tahiti. Our results indicate that the El Niño-
Southern Oscillation was active during Heinrich Stadial 1,
consistent with climate model simulations of enhanced El Niño-
Southern Oscillation variability at that time. Furthermore,
a greater El Niño-Southern Oscillation influence in the South
Pacific during Heinrich Stadial 1 is suggested, resulting from
a southward expansion or shift of El Niño-Southern Oscillation
sea surface temperature anomalies.
STUDY NOTES: Sr/Ca and d18O data from a fossil Porites coral recovered at Tahiti,
French Polynesia. Fossil Porites coral (310-M0024A-11R-2W 1-62)
was recovered by IODP Expedition 310 in the central tropical South
Pacific at 113 m below present sea level off Tiarei on the north side
of the island of Tahiti (French Polynesia, IODP Hole M0024A).
Rigorous screening for diagenetic alteration using a variety of
methods reveals that the aragonitic coral skeleton is well preserved.
Two highly consistent U-Th ages indicate that the coral grew
14.994±0.025 ka before the present (ka BP; ‘present’ is defined
as AD 1950). In the skeleton of this coral, we analyse the Sr/Ca
temperature proxy (and d18O) at monthly resolution representing
an interval of 22 years. The fossil Tahiti coral, which lived
in a water depth of <=10 m, more likely in <=5 m, at 15.0 ka BP,
provides an ultrahigh-resolution snapshot of tropical Pacific
climate variability during the cold Heinrich Stadial 1 of the
North Atlantic. More information can be found in Felis et al., 2012.
