browse graphicPaleoclimatology - Paleoceanography
This archived Paleoclimatology Study is available from the NOAA National Centers for Environmental Information (NCEI), under the World Data Service (WDS) for Paleoclimatology. The associated NCEI study type is Paleoceanography. The data include parameters of paleoceanography with a geographic location of Gulf Of Mexico, North Atlantic Ocean. The time period coverage is from 12898 to 10206 in calendar years before present (BP). See metadata information for parameter and study location details. Please cite this study when using the data.

STUDY NOTES: Grain size data from core KNR166-2-25JPC collected near the Dry Tortugas, Southwest Florida margin, spanning the Younger Dryas interval (~13 - 10 kyr BP).
ABSTRACT SUPPLIED BY ORIGINATOR: The risk posed by intensification of North Atlantic hurricane activity remains controversial, in part due to a lack of available storm proxy records that extend beyond the relatively stable climates of the late Holocene. Here we present a record of storm-triggered turbidite deposition offshore the Dry Tortugas, south Florida, USA, that spans abrupt transitions in North Atlantic sea-surface temperature and Atlantic Meridional Overturning Circulation (AMOC) during the Younger Dryas (12.9-11.7 ka). Despite potentially hostile conditions for cyclogenesis in the tropical North Atlantic at that time, our record and numerical experiments suggest that strong hurricanes may have regularly affected Florida. Less severe surface cooling at mid-latitudes (~20-40N) than across much of the tropical North Atlantic (~10-20N) in response to AMOC reduction may best explain strong hurricane activity during the Younger Dryas near the Dry Tortugas and possibly along the entire southeastern coast of the United States.
PurposeRecords of past climate and ocean circulation derived from marine sediments. Parameter keywords describe what was measured in this dataset. Additional summary information can be found in the abstracts of papers listed in the dataset citations.
