Deglacial abrupt climate change in the Atlantic Warm Pool:
A Gulf of Mexico perspective.
Paleoceanography, 25, PA4221, doi:10.1029/2010PA001928
During the last deglaciation, Greenland ice core and North Atlantic
sediment records exhibit multiple abrupt climate events including
the Younger Dryas cold episode (12.9-11.7 ka). However, evidence
for the presence of the Younger Dryas in the Gulf of Mexico (GOM)
and the relationship between GOM sea surface temperature (SST)
and high-latitude climate change is less clear. We present new
Mg/Ca-SST records from two varieties of the planktonic foraminifer
Globigerinoides ruber (white and pink) to assess northern GOM SST
history from approximately 18.4-10.8 ka. Thirty-five accelerator
mass spectrometry (AMS) 14C dates from Orca Basin core MD02-2550
provide excellent age control and document high sedimentation rates
(~40 cm/kyr). G. ruber (white and pink) Mg/Ca-SST data exhibit
increases (~4.6 ± 0.6°C and ~2.2 ± 0.5°C, respectively) from at
least 17.8-16.6 ka, with nearly decadal resolution that are early
relative to the onset of the Bolling-Allerod interstadial. Moreover,
G. ruber (white) SST decreases at 16.0-14.7 ka (~1.0 ± 0.5°C) and
12.8-11.6 ka (~2.4 ± 0.6°C) correlate to the Oldest and Younger
Dryas in Greenland and Cariaco Basin. The G. ruber (pink) SST record,
which reflects differences in seasonality and/or depth habitat,
is often not in phase with G. ruber (white) and closely resembles
Antarctic air temperature records. Overall, it appears that
Orca Basin SST records follow Antarctic air temperature early
in the deglacial sequence and exhibit enhanced seasonality during
Greenland stadials.
STUDY NOTES: High resolution foraminiferal Mg/Ca data and SST reconstructions
for the deglacial period for a core from the Orca Basin,
northern Gulf of Mexico.
