Here, we present two near-annually resolved hurricane reconstructions from sediment archived in two blue holes located only 300 m apart on the northern margin of Grand Bahama. These two blue holes provide a replicated signal of hurricanes passing within a 50–100 km radius over the last 1,800 years, and the long-term reconstructions document multiple 50-to-150-year intervals when hurricane frequency was significantly higher than it has been over the last 100 years. These two records were first merged into a single stack, and then compiled with five other high-resolution reconstructions from across the Bahamian Archipelago to form a single 1500-year record of Bahamian hurricane frequency. This new Bahamian Compilation documents more hurricanes passing ~75°W from 21°N to 26°N during the Little Ice Age (LIA; 1300–1850 CE) relative to the prior millennium and the last 170 years. The US Eastern Seaboard also experienced heightened hurricane activity during the LIA, whereas the Gulf of Mexico and Southern Caribbean were inactive. This suggests that despite a globally cooler climate, regional climate conditions during the LIA remained favorable for cyclogenesis and intensification along certain Atlantic hurricane pathways. Perhaps heightened Sahel rainfall during the LIA indicates an increase in African Easterly waves, which in turn possibly seeded more tropical cyclones in the Atlantic Main Development Region. #--------------------------------------- # Funding_Agency # Funding_Agency_Name: National Science Foundation # Grant: OCE-1356509, OCE-1356708, OCE-1854917, OCE-1903616, OCE-1903616, ICER-1854980 #--------------------------------------- # Funding_Agency # Funding_Agency_Name: Dalio Explore Foundation # Grant: Dalio Explore Grant #--------------------------------------- # Funding_Agency # Funding_Agency_Name: Geological Society of America # Grant: Student Research Grant (NSF award #1712071 #--------------------------------------- # Funding_Agency # Funding_Agency_Name: Texas Sea Grant # Grant: NA18-2019-E/GIA-2019-Winkler #--------------------------------------- # Funding_Agency # Funding_Agency_Name: Texas A&M University at Galveston # Grant: Boost Dissertation Fellowship #--------------------------------------- # Site Information # Site_Name: Bahamian Archipelago # Location: Bahamas # Northernmost_Latitude: 26.66 # Southernmost_Latitude: 21.72 # Easternmost_Longitude: -71.81 # Westernmost_Longitude: -79.81 # Elevation_m: #--------------------------------------- # Data_Collection # Collection_Name: BHACstand6_Comp Records_Used # First_Year: 355 # Last_Year: 2020 # Time_Unit: year Common Era # Parameter_Keywords: reconstruction # Core_Length_m: # Notes: #--------------------------------------- # Synthesis Collection Metadata Fields # NOTE: These are the fields used to capture the metadata about data sources used in a synthesis study. # Each row of this table corresponds to a column in the SourceDataTable file listed above in the Online_Resource URLs. # The rows here are linked to the columns in the data table using the ID field. # Metadata fields that follow that are preceded by "##" in columns one and two. ## dataID dataset ID ## FullDataSetCode A name for the data collection ## minLatitude southernmost latitude of site bounding box in decimal degrees North ## maxLatitude northernmost latitude of site bounding box in decimal degrees North ## minLongitude westernmost longitude of site bounding box in decimal degrees East ## maxLongitude easternmost longitude of site bounding box in decimal degrees East ## startYear first year of record that was included in compilation in years CE ## endYear last year of record that was included in compilation in years CE ## Citation citation text and DOI for original publication source of data ## Original_Source_Data_URL Original Source URL and DOI(if available) for the data presented here #--------------------------------------- # RecordsUsed_Metadata: # Missing_Values: dataID FullDataSetCode minLatitude maxLatitude minLongitude maxLongitude startYear endYear Citation Original_Source_Data_URL Andros Andros Blue Hole Stack (AM2+AM4+AM5), Bahamas 23.76938 23.7928 -77.71955 -77.6495 450 2020 Wallace et al 2019 (doi: 10.1029/2019PA003665); Winkler et al 2020 (doi: 10.1038/s41598-020-73132-x) NOAA/WDS-Paleo study 27730 (doi: 10.25921/yhre-5945); NOAA/WDS-Paleo study 31795 (doi: 10.25921/3zya-mj09) LIBH Long Island Blue Hole, Bahamas 23.265 23.265 -75.117 -75.117 947 2016 Wallace et al 2021 (doi: 10.1029/2020PA004156) NOAA/WDS-Paleo study 32134 (doi:10.25921/f8zv-xw05) CAOS Middle Caicos Blue Hole, Turks and Caicos 21.719 21.719 -71.812 -71.812 610 2020 Wallace et al 2021 (doi: 10.1016/j.quascirev.2021.107126) NOAA/WDS-Paleo study 33652 (doi: 10.25921/h3k2-qj41) TPBH Thatchpoint Blue Hole, Abaco Island, Bahamas 26.323369 26.323369 -77.293362 -77.293362 1337 2020 Winkler et al 2020 (doi: 10.1038/s41598-020-73132-x) NOAA/WDS-Paleo study 31795 (doi: 10.25921/3zya-mj09) GBAM Turtle Pond and Lane's Delight Blue Hole, Grand Bahama 26.658 26.661 -78.592 -78.59 355 2016 this study this study CSAL Hine's Hole, Cay Sal Bank, Bahamas 23.86 23.87 -79.81 -79.8 1482 2010 Winkler et al 2022 (doi: 10.1016/j.margeo.2021.106653) NOAA/WDS-Paleo study 34252 (doi: 10.25921/r26a-sh48)
