Ice loss from the East Antarctic Ice Sheet during late Pleistocene interglacials

Understanding ice sheet behaviour in the geological past is essential for evaluating the role of the cryosphere in the climate system and for projecting rates and magnitudes of sea level rise in future warming scenarios1,2,3,4. Although both geological data5,6,7 and ice sheet models3,8 indicate that marine-based sectors of the East Antarctic Ice Sheet were unstable during Pliocene warm intervals, the ice sheet dynamics during late Pleistocene interglacial intervals are highly uncertain3,9,10. Here we provide evidence from marine sedimentological and geochemical records for ice margin retreat or thinning in the vicinity of the Wilkes Subglacial Basin of East Antarctica during warm late Pleistocene interglacial intervals. The most extreme changes in sediment provenance, recording changes in the locus of glacial erosion, occurred during marine isotope stages 5, 9, and 11, when Antarctic air temperatures11 were at least two degrees Celsius warmer than pre-industrial temperatures for 2,500 years or more. Hence, our study indicates a close link between extended Antarctic warmth and ice loss from the Wilkes Subglacial Basin, providing ice-proximal data to support a contribution to sea level from a reduced East Antarctic Ice Sheet during warm interglacial intervals. While the behaviour of other regions of the East Antarctic Ice Sheet remains to be assessed, it appears that modest future warming may be sufficient to cause ice loss from the Wilkes Subglacial Basin.

Extended data figures and tables

  1. Extended Data Fig. 1 Neodymium isotope data for bulk detrital sediment, <63 μm fraction, and reductive sediment leachates in U1361A, in comparison to regional bedrock endmembers.

    a, Down core measurements on the different fractions, with boxes and arrows on the right indicating bedrock endmember compositions in the region (refs 5,39 and references cited therein). Horizontal lines indicate Holocene core top values for bulk detrital samples (red dashed line) and 1 h leachate samples (black dashed line). Error bars are 2 s.d. external reproducibility, and are smaller than the symbol sizes where not shown. b, Regional bedrock map, with those same bedrock endmembers located by coloured shading (map redrawn from ref. 5, with topography from ref. 12, and the subglacial extent of the FLIP shown by a green dotted outline inferred from ref. 21). In addition to the three endmembers shown in a, purple shading on the map indicates Archaean to Proterozoic basement rocks of the Adélie Craton, with highly unradiogenic Nd isotopic compositions (εNd = –20 to –29). CB, Central Basin; HB, Horn Bluff. For interpretation of the leachate and detrital Nd isotope data, see Methods. Map redrawn from ref. 5 with permission.

  2. Extended Data Fig. 2 Neodymium isotope versus Sr isotope crossplot for late Pleistocene fine fraction (<63 μm) sediments in U1361A, in comparison to Pliocene detrital sediments from Site U1361 and regional bedrock endmembers.

    The Pliocene data are based on either the <63 μm or <150 μm size fractions5,39,52, while bedrock endmember compositions are based on refs 5,39 (and references cited therein). These data indicate identical trends between the Pliocene and Pleistocene, from which we infer similar provenance variations during both these intervals.

  3. Extended Data Fig. 3 Age model for U1361A.

    a, LR04 benthic oxygen isotope (δ18O) stack72, labelled with interglacial MIS numbers. b, Age–depth constraints for U1361A cores 1H and 2H, plotted alongside lithology. Vertical bars for each datum indicate upper and lower depth constraints in U1361A (Supplementary Table 8). Black dashed line is a linear model fit through the Holocene radiocarbon age, H. karstenii last common occurrence (LCO), A. ingens last occurrence (LO) (upper and lower depths), and the base of chron C1n (*upper depth only, based on the splice to U1361B) (Supplementary Table 8). Forced to an intercept of 0 ka at 0 mbsf, this trendline produces the age–depth equation y = 64.314x, where y is age (ka; kyr ago) and x is depth (mbsf). This equation was used to calculate ages for Fig. 3d, e. Grey dotted lines tie lithological transitions to MIS boundaries, based on our age–depth constraints. Note that the Pleistocene section of the core below MIS 12 is affected by sediment disturbance, with extreme disturbance from 9.0–11.67 mbsf (soupy) and 11.67–14.26 mbsf (flow) represented schematically with a zigzag line. We have therefore restricted our provenance study to the upper ~7.5 mbsf.
