|a The largest abrupt climatic reversal of the Holocene
interglacial, the cooling event 8.6–8.2 thousand years ago
(ka), was probably caused by catastrophic release of glacial
Lake Agassiz-Ojibway, which slowed Atlantic meridional
overturning circulation (AMOC) and cooled global climate.
Geophysical surveys and sediment cores from Chesapeake
Bay reveal the pattern of sea level rise during this event. Sea
level rose [plus or minus]14 m between 9.5 to 7.5 ka, a pattern consistent
with coral records and the ICE-5G glacio-isostatic
adjustment model. There were two distinct periods at
[plus or minus]8.9–8.8 and [plus or minus]8.2–7.6 ka when Chesapeake marshes
were drown as sea level rose rapidly at least [plus or minus]12 mm yr-1.
The latter event occurred after the 8.6–8.2 ka cooling event,
coincided with extreme warming and vigorous AMOC
centered on 7.9 ka, and may have been due to Antarctic Ice
Sheet decay |
