They show a striking match with Bond events and a significant pacing at ~800 yr, a dominant periodicity present in sea surface temperature records from both the North Atlantic and equatorial Pacific Oceans that is possibly related to periods of low solar activity (high 14C based on the atmospheric 14C record). The precipitation variations over central-eastern Brazil are broadly antiphased with the Asian and Indian Monsoons during Bond events and show marked differences in duration and structure between the early and late Holocene. Our results suggest that these abrupt multicentennial precipitation events are primarily linked to changes in the North Atlantic meridional overturning circulation (AMOC). Anomalous cross-equatorial flow induced by negative AMOC phases may have modulated not only the monsoon in South America but also affected El Nino-like conditions in the tropical Pacific during the Holocene. #-------------------- # Funding_Agency # Funding_Agency_Name: US National Science Foundation # Grant_Number: 0502535, 1103403 #-------------------- # Funding_Agency # Funding_Agency_Name: Fundacao de Amparo a Pesquisa do Estado de Sao Paulo (FAPESP), Brazil # Grant_Number: #-------------------- # Funding_Agency # Funding_Agency_Name: Coordination for the Improvement of Higher Education Personnel (CAPES) # Grant_Number: #-------------------- # Site_Information # Site_Name: Lapa Grande Cave # Location: Brazil # Northernmost_Latitude: -14.4227 # Southernmost_Latitude: -14.4227 # Easternmost_Longitude: -44.3656 # Westernmost_Longitude: -44.3656 # Elevation: #-------------------- # Data_Collection # Collection_Name: LG11 # First_Year: 10200 # Last_Year: 6210 # Time_Unit: cal yr BP # Core_Length: # Parameter_Keywords: oxygen isotopes # Notes: #-------------------- # Chronology_Information # Chronology: # # #------------------ # Variables # # PaST_Thesaurus_Download_Resource: https://www.ncdc.noaa.gov/paleo/skos/past-thesaurus.rdf # PaST_Thesaurus_Download_Description: Paleoenvironmental Standard Terms (PaST) Thesaurus terms, definitions, and relationships in SKOS format. # # variables format: shortname what,material,error,units,seasonality,data_type,detail,method, C(har) or N(umeric) data,additional information # ##
