Regional climate variability in the western subtropical North Atlantic
during the past two millennia.
Paleoceanography, 26, PA2206, doi:10.1029/2010PA002038.
Western subtropical North Atlantic oceanic and atmospheric
circulations connect tropical and subpolar climates. Variations
in these circulations can generate regional climate anomalies
that are not reflected in Northern Hemisphere averages.
Assessing the significance of anthropogenic climate change
at regional scales requires proxy records that allow recent
trends to be interpreted in the context of long-term regional
variability. We present reconstructions of Gulf Stream sea
surface temperature (SST) and hydrographic variability during
the past two millennia based on the magnesium/calcium ratio
and oxygen isotopic composition of planktic foraminifera
preserved in two western subtropical North Atlantic sediment
cores. Reconstructed SST suggests low-frequency variability
of ~1°C during an interval that includes the Medieval Climate
Anomaly (MCA) and the Little Ice Age (LIA). A warm interval
near 1250 A.D. is distinct from regional and hemispheric
temperature, possibly reflecting regional variations in
ocean-atmosphere heat flux associated with changes in
atmospheric circulation (e.g., the North Atlantic Oscillation)
or the Atlantic Meridional Overturning Circulation. Seawater
d18O, which is marked by a fresher MCA and a more saline LIA,
covaries with meridional migrations of the Atlantic Intertropical
Convergence Zone. The northward advection of tropical salinity
anomalies by mean surface currents provides a plausible mechanism
linking Carolina Slope and tropical Atlantic hydrology.
STUDY NOTES: Binned Mg/Ca and d18O based temperature, d18Ow and salinity
estimates from Saenger et al., 2011, figures 6 and 10.
