Regionally coherent Little Ice Age cooling in the Atlantic Warm Pool.
Geophys. Res. Lett., 36, L21703, doi:10.1029/2009GL040445
We present 2 new decadal-resolution foraminiferal Mg/Ca-SST records
covering the past 6-8 centuries from the northern Gulf of Mexico (GOM).
These records provide evidence for a Little Ice Age (LIA) cooling of 2°C,
consistent with a published Mg/Ca record from Pigmy Basin. Comparison
of these 3 records with existing SST proxy records from the GOM-Caribbean
region show that the magnitude of LIA cooling in the Atlantic Warm Pool
(AWP) was significantly larger than the mean hemispheric cooling of <1°C.
We propose that a reduction in the intensity and spatial extent of the
AWP during the LIA, combined with associated changes in atmospheric
circulation may account for the regional SST patterns observed in the
GOM-Caribbean region during the LIA.
STUDY NOTES: Foraminiferal Mg/Ca SST reconstructions from the Fisk and Garrison
Basins in the northern Gulf of Mexico covering the last 600 years
at decadal resolution. Mg/Ca measurements are on the 250-300 micron
size fraction of Globigerinoides ruber (white).
Mg/Ca is converted to SST using the equation: Mg/Ca=0.449exp(0.09*SST).
