Herho # Published_Date_or_Year: 2023 # Published_Title: d18O of marine-influenced Tectona grandis from equatorial Indonesia: A local rainfall amount and remote ENSO indicator # Journal_Name: Paleoceanography and Paleoclimatology # Volume: submitted # Edition: # Issue: # Pages: # Report_Number: # DOI: # Publisher: AGU/Wiley # ISBN: # Online_Resource: # Full_Citation: # Abstract: The hydroclimatic response of the El Nino-Southern Oscillation (ENSO) to external radiative forcing remains controversial and difficult to project with confidence for the 21st century, but potentially very useful in this regard are annually-resolved paleoclimatic reconstructions spanning the pre- and post-industrial eras may provide hindcasting and diagnostic targets. Here we report triplicate delta18O observations from dendro-chronologically dated teak (Tectona grandis L. f.) alpha-cellulose samples collected at Muna Island in Sulawesi, Indonesia (5.3 S, 123 E, elev. 10m), for November-April growing seasons during the period 1969/70-2004/5. Age-modeled, annually averaged delta18O anomalies are significantly correlated with simulated delta18O and NINO3.4 SST anomaly index values over the study period, suggesting that replicated multicentury \mbox{$\alpha$-cellulose} records from this archive may be interpreted as ENSO indicators, and may be used to assess the hydroclimatic response, if any, of ENSO to volcanic, solar and greenhouse radiative forcings, and the unforced variation. #-------------------- # Funding_Agency # Funding_Agency_Name: US Agency for International Development # Grant: P-2409 #-------------------- # Funding_Agency # Funding_Agency_Name: US National Science Foundation # Grant: 1903626 #-------------------- # Site_Information # Site_Name: Muna, Sulawesi # Location: Indonesia # Northernmost_Latitude: -5.3 # Southernmost_Latitude: -5.3 # Easternmost_Longitude: 123 # Westernmost_Longitude: 123 # Elevation_m: 10 #-------------------- # Data_Collection # Collection_Name: Muna Mun2.2 d18O IND005 Nurhati2023 # Earliest_Year: 1970 # Most_Recent_Year: 2005 # Time_Unit: year Common Era # Core_Length_m: # Parameter_Keywords: oxygen isotopes, width # Notes: #-------------------- # Species - Note: this section is used only for the tree ring and fire history data types. # Tree_Species_Download_Resource: https://www.ncei.noaa.gov/pub/data/paleo/templates/tree-species-code.csv # Tree_Species_Download_Description: List of accepted tree species names and codes. # # Species_Name: Tectona grandis L. f. # Common_Name: teak # Tree_Species_Code: TEGR #-------------------- # Chronology_Information # Chronology: Tree-ring width crossdating from D'Arrigo et al (2006, 2010), samples mun03a (mun031) and mun10a (mun101) are at: https://www.ncei.noaa.gov/access/paleo-search/study/12628); estimated widths for sample mun02b (mun22) and notes on sampling for isotopic analysis are in the associated NOAA template file. #-------------------- # Variables # # PaST_Thesaurus_Download_Resource: https://www.ncei.noaa.gov/pub/data/paleo/PaST-thesaurus/SKOS/past-thesaurus-v1.0.rdf # PaST_Thesaurus_Download_Description: Paleoenvironmental Standard Terms (PaST) Thesaurus terms, definitions, and relationships in SKOS format. # # For Additional Help in Describing Variables see: # Thesaurus Terms and Definitions- https://www.ncdc.noaa.gov/paleo-search/cvterms # # Variables are defined using these elements: Short_name what,material,error,units,seasonality,data_type,detail,method,data_format,additional_information # Note: the Short_name does not require a PaST term. # ## Year age,,,year Common Era,,tree ring,,,N,tree-ring widths ## start_sample sample identification,,, ,,tree ring,,,N,first sample within year of data row; tree-ring annual subsample ## end_sample sample identification,,, ,,tree ring,,,N,end sample within year of data row; tree-ring annual subsample ## TRW total ring width,,,micrometer,,tree ring,,,N,tree-ring annual increment ## notes notes,,,,,,,,C,subsampling notes #-------------------- # Data: # Data line format - tab-delimited text, variable short name as header # Missing_Values: NaN Year start_sample end_sample TRW notes 2005 357 364 2807 NaN 2004 365 372 1313 NaN 2003 373 382 3511 NaN 2002 383 390 791 NaN 2001 391 398 2087 "*Note: sample 397 is marked as being “for 2000” but 398 appears to be the actual end of 2001.
