Eolian deposition in the North Pacific preserved past information about the westerlies, the major wind system delivering Asian dust to the Pacific. A continuous, high-resolution eolian flux record since 23 Ma was reconstructed from sediments at Deep Sea Drilling Project (DSDP) Site 296 in the North Pacific. Combined with dust flux at Ocean Drilling Program (ODP) Site 1208, variations in their difference indicated a northwards shift of the westerlies during 23-9 Ma and a relatively stable state since then. We suggest that Tibetan uplift since the early Miocene began to drive the poleward shift of the westerlies until 9 Ma, after which the westerlies remained relatively stable over Asia on million-year timescales. #--------------------------------------- # Funding_Agency # Funding_Agency_Name: National Natural Science Foundation of China # Grant: 42125602, 42076052 #--------------------------------------- # Funding_Agency # Funding_Agency_Name: Strategic Priority Research Program of Chinese Academy of Sciences # Grant: XDB40010100 #--------------------------------------- # Funding_Agency # Funding_Agency_Name: Innovation Project # Grant: 2022QNLM050203, MGQNLM-KF202001 #--------------------------------------- # Funding_Agency # Funding_Agency_Name: Taishan and Aoshan Talents Program # Grant: 2017ASTCP-ES01 #--------------------------------------- # Site_Information # Site_Name: ODP Site 1208 # Location: North Pacific Ocean # Northernmost_Latitude: 36.13 # Southernmost_Latitude: 36.13 # Easternmost_Longitude: 158.2 # Westernmost_Longitude: 158.2 # Elevation_m: 3346 #--------------------------------------- # Data_Collection # Collection_Name: ODP-1208 Eolian Flux # First_Year: 23370000 # Last_Year: 40000 # Time_Unit: calendar year before present # Core_Length_m: 320 # Parameter_Keywords: # Notes: #--------------------------------------- # Chronology_Information # Chronology: #--------------------------------------- # Variables # PaST_Thesaurus_Download_Resource: https://www.ncei.noaa.gov/access/paleo-search/skos/past-thesaurus.rdf # PaST_Thesaurus_Download_Description: Paleoenvironmental Standard Terms (PaST) Thesaurus terms, definitions, and relationships in SKOS format. # # Data variables follow that are preceded by "##" in columns one and two. # Variables list, one per line, shortname-tab-var components: what, material, error, units, seasonality, data type, detail, method, C or N for Character or Numeric data) # ## Depth depth,,,meter,,Paleoceanography,,,N, ## Age age,,,million years ago,,Paleoceanography,,,N, ## Siliciclastic_fraction mineral matter,,,percent,,Paleoceanography,,,N,chemical extraction ## Eolian_fraction dust,,,percent,,Paleoceanography,,,N,two end-members mixing ## Eolian_flux dust,,,gram per square centimeter per kiloyear,,Paleoceanography,,,N,calculated as MAR siliciclastic fraction eolian fraction #------------------------ # Data: # Data lines follow (have no #) # Data line format -
