Southward migration of the global monsoon is thought to link the hemispheres during deglaciation, but vital evidence from the southern sector of the vast Australasian monsoon system is yet to emerge. Here we present a 230thorium-dated stalagmite oxygen isotope record of millennial-scale changes in Australian–Indonesian monsoon rainfall over the last 31,000 years. The record shows that abrupt southward shifts of the Australian–Indonesian monsoon were synchronous with North Atlantic cold intervals 17,600–11,500 years ago. The most prominent southward shift occurred in lock-step with Heinrich Stadial 1 (17,600–14,600 years ago), and rising atmospheric carbon dioxide. Our findings show that millennial-scale climate change was transmitted rapidly across Australasia and lend support to the idea that the 3,000-year-long Heinrich 1 interval could have been critical in driving the last deglaciation. #------------------ # Funding_Agency # Funding_Agency_Name: # Grant: #------------------ # Site_Information # Site_Name: Liang Luar Cave # Location: Asia, Indonesia, Flores Island # Country: Indonesia # Northernmost_Latitude: -8.533 # Southernmost_Latitude: -8.533 # Easternmost_Longitude: 120.433 # Westernmost_Longitude: 120.433 # Elevation: 550 #------------------ # Data_Collection # Collection_Name: Composite stalagmite # Earliest_Year: 23.9 # Most_Recent_Year: 0 # Time_Unit: cal yr ka BP # Core_Length: m # Notes: Supplementary Table S4. Composite stalagmite δ18O record for Flores. Stalagmite δ18O records for Liang Luar are based on data in Supplementary Table S3 and Griffiths, M. L. et al. Increasing Australian-Indonesian monsoon rainfall linked to early Holocene sea-level rise. Nat. Geosci. 2, 636-639. (2009) and Lewis, S. C. et al. High-resolution stalagmite reconstructions of Australian–Indonesian monsoon rainfall variability during Heinrich stadial 3 and Greenland interstadial 4. Earth Planet. Sci. Lett. 303, 133-142 (2011). The records were resampled at 100-year resolution and averaged to produce a spliced composite record. Standard errors were calculated for 100-year intervals in overlapping sections of the records. #------------------ #------------------ # Chronology: # # # # # # # # #---------------- # Variables # # Data variables follow are preceded by "##" in columns one and two. # Data line variables format: Variables list, one per line, shortname-tab-longname-tab-longname components (9 components: what, material, error, units, seasonality, archive, detail, method, C or N for Character or Numeric data) # ##age_ka_bp Age,,,cal yr ka bp,,,,,N ##d18OcarbVPDBavg Delta 18O,calcium carbonate,,per mil VPDB,,speleothem,average,,N ##d18OcarbVPDBavg-err Delta 18O,calcium carbonate,± Standard Error,per mil VPDB,,speleothem,average,,N #---------------- # Data: # Data lines follow (have no #) # Data line format - tab-delimited text, variable short name as header # Missing Values: # age_ka_bp d18OcarbVPDBavg 18OcarbVPDBavg-err 0 -6.1 0.1 -6.17 0.09 0.2 -6 0.1 0.3 -6.02 0.01 0.4 -6.41 0.07 0.5 -6.36 0.14 0.6 -6.18 0.12 0.7 -6.32 0.25 0.8 -6.17 0.13 0.9 -6.15 0.15 1 -6.06 0.23 1.1 -6.27 0.2 1.2 -6.22 0.14 1.3 -6.1 0 1.4 -6.09 0 1.5 -6.01 0.01 1.6 -6.05 0.05 1.7 -6.28 0.06 1.8 -6.56 0.19 1.9 -6.45 0.16 2 -6.41 0.16 2.1 -6.38 0.04 2.2 -6.41 0.21 2.3 -6.22 0.07 2.4 -6.22 0.12 2.5 -6.21 0.13 2.6 -6.28 0.12 2.7 -6.09 0.08 2.8 -6.12 0.03 2.9 -6.05 3 -6.07 3.1 -6.13 3.2 -6.23 3.3 -6.06 3.4 -6.03 3.5 -6.02 3.6 -6.05 3.7 -6.11 0.07 3.8 -6.09 0.15 3.9 -6.09 0.22 4 -6.39 0.03 4.1 -6.38 0.02 4.2 -5.98 0.29 4.3 -6.09 0.08 4.4 -6.05 0.15 4.5 -6.08 0.12 4.6 -5.87 0.28 4.7 -6.03 0.04 4.8 -5.89 0.11 4.9 -5.96 0.23 5 -5.84 0.31 5.1 -5.99 0.23 5.2 -5.91 0.24 5.3 -6.05 0.25 5.4 -6.03 0.22 5.5 -6.08 0.12 5.6 -6.05 0.17 5.7 -6.28 0.03 5.8 -6.38 0.04 5.9 -6.27 0.07 6 -6.18 0.02 6.1 -6.37 0.12 6.2 -6.15 0.04 6.3 -6.22 0.03 6.4 -6.24 0.01 6.5 -6.39 6.6 -6.35 6.7 -6.15 6.8 -6.31 6.9 -6.16 7 -6.14 7.1 -6.31 7.2 -6.12 7.3 -6.19 7.4 -6.23 7.5 -6.2 7.6 -6.2 7.7 -6.1 7.8 -6.23 7.9 -5.83 8 -6.08 8.1 -5.91 8.2 -5.84 8.3 -5.51 8.4 -5.58 8.5 -5.73 8.6 -5.65 0.13 8.7 -5.6 0.2 8.8 -5.75 0.03 8.9 -5.56 0.03 9 -5.61 0 9.1 -5.57 0.02 9.2 -5.45 0.04 9.3 -5.44 0.1 9.4 -5.34 0.15 9.5 -5.1 0.02 9.6 -5.1 0.11 9.7 -4.94 0.15 9.8 -5.19 0.06 9.9 -4.91 0.14 10 -4.98 0.04 10.1 -4.81 0.19 10.2 -4.91 0.05 10.3 -4.91 0.02 10.4 -4.81 0.03 10.5 -4.74 0.06 10.6 -4.78 0.11 10.7 -4.54 0.07 10.8 -4.5 0.06 10.9 -4.53 0.07 11 -4.47 0.13 11.1 -4.34 0.1 11.2 -4.31 0.06 11.3 -4.32 0.07 11.4 -4.29 0.05 11.5 -4.55 0.09 11.6 -4.65 0.04 11.7 -4.55 0.06 11.8 -4.79 0.01 11.9 -4.72 0.07 12 -4.78 0.03 12.1 -4.71 0.08 12.2 -4.83 0.08 12.3 -4.76 0.09 12.4 -4.72 0.04 12.5 -4.74 0.1 12.6 -4.77 0.12 12.7 -4.86 0.05 12.8 -4.79 0.05 12.9 -4.75 0.05 13 -4.63 0.02 13.1 -4.66 0.01 13.2 -4.64 0.06 13.3 -4.53 0.02 13.4 -4.58 0.02 13.5 -4.59 0.05 13.6 -4.47 0.06 13.7 -4.52 0 13.8 -4.64 13.9 -4.59 14 -4.57 14.1 -4.67 14.2 -4.5 14.3 -4.6 14.4 -4.49 0.05 14.5 -4.47 0.02 14.6 -4.54 0.01 14.7 -4.7 0.01 14.8 -4.88 0.07 14.9 -4.86 0.06 15 -4.81 0.07 15.1 -4.8 0.11 15.2 -4.98 0.02 15.3 -5.06 0.04 15.4 -5.13 0.04 15.5 -5.17 0.02 15.6 -5.17 0.05 15.7 -5.15 0.1 15.8 -5.14 0.14 15.9 -5.14 0.14 16 -5.12 0.12 16.1 -5.22 0.14 16.2 -5.29 0.12 16.3 -5.27 0.08 16.4 -5.21 0.02 16.5 -5.11 0.07 16.6 -5.07 0.15 16.7 -5.04 0.05 16.8 -5.06 0.2 16.9 -5.17 0.12 17 -5.3 0.19 17.1 -5.33 0.2 17.2 -5.35 0.13 17.3 -5.26 0.1 17.4 -5.09 0.12 17.5 -5.24 0 17.6 -5.08 17.7 -4.75 17.8 -4.54 17.9 -4.66 18 -4.61 18.1 -4.42 18.2 -4.47 18.3 -4.51 18.4 -4.55 18.5 -4.72 18.6 -4.93 18.7 -4.93 18.8 -5.08 18.9 -5.11 19 -4.95 19.1 -4.74 19.2 -5.32 19.3 -5.44 19.4 -5.68 19.5 -4.93 19.6 -5.62 19.7 -5.6 19.8 -5.62 19.9 -5.17 0.43 20 -5.2 0.48 20.1 -5.06 0.26 20.2 -5.12 0.21 20.3 -5.1 0.12 20.4 -5.11 0.09 20.5 -5.17 0.11 20.6 -5.19 0.15 20.7 -5.17 0.13 20.8 -5.22 0.07 20.9 -5.25 0.05 21 -5.19 0.02 21.1 -5.07 0.22 21.2 -5.17 0.04 21.3 -5.22 0.14 21.4 -5.29 0.05 21.5 -5.32 0.1 21.6 -5.26 0.1 21.7 -5.25 0.07 21.8 -5.19 0.17 21.9 -5.06 0.18 22 -5.12 0.09 22.1 -5.14 0.13 22.2 -5.07 0.1 22.3 -5.1 0.11 22.4 -5.07 0.1 22.5 -4.95 0.06 22.6 -5.05 0.07 22.7 -5.05 0.09 22.8 -4.97 0.05 22.9 -4.97 0.09 23 -4.94 0.09 23.1 -4.92 0.13 23.2 -4.96 0.14 23.3 -4.95 0.15 23.4 -4.86 0.14 23.5 -4.99 0.23 23.6 -4.59 23.7 -4.61 23.8 -4.65 23.9 -4.69
