However, the interpretation of the Qunf d18Oc remains in dispute. Here we provide multiple proxy records from Qunf Cave and climate model simulations to reconstruct the Holocene local and regional hydroclimate changes. The results indicate that besides the Indian summer monsoon, the North African summer monsoon also contributes water vapor to southern Oman during the early to middle Holocene. In principle, Qunf d18Oc values reflect integrated oxygen-isotope fractionations over a broad moisture transport swath from moisture sources to the cave site, rather than local precipitation amount alone, and thus the Qunf d18Oc record characterizes primary changes in the super-monsoon regime across the Holocene. In contrast, other Qunf Cave proxy records appear to suggest an overall slightly increased or unchanged wetness over the Holocene at the cave site. #--------------------------------------- # Funding_Agency # Funding_Agency_Name: National Natural Science Foundation of China # Grant: 41888101, 42150710534, 4197020225 #--------------------------------------- # Site_Information # Site_Name: Qunf Cave # Location: Oman # Northernmost_Latitude: 17.17 # Southernmost_Latitude: 17.17 # Easternmost_Longitude: 54.3 # Westernmost_Longitude: 54.3 # Elevation_m: 650 #--------------------------------------- # Data_Collection # Collection_Name: Q5_TM # First_Year: 10599 # Last_Year: 486 # Time_Unit: calendar year before present # Core_Length_m: # Parameter_Keywords: age control, trace metals # Notes: #--------------------------------------- # Chronology_Information # Chronology: Uranium-Thorium # Chronology_Download_Resource: https://www.ncei.noaa.gov/pub/data/paleo/templates/noaa-wds-paleo-uth-terms.csv # Chronology_Download_Description: Uranium-Thorium terms and definitions. # Chronology_Notes: Dating work for stalagmite Q5 done at Xi’an Jiaotong University Isotope Laboratory using multi-collector inductively coupled plasma mass spectrometers (Thermo-Finnigan Neptune-plus). # Rejection_Rationale: # 238U_Decay_Constant: # 234U_Decay_Constant: # 230Th_Decay_Constant: # Initial_230Th/232Th: # Initial_230Th/232Th_Method: # Age_Model_Method: Constructing Proxy Records from Age (COPRA) program of Breitenbach et al.
