Correction for Farmer et al., The Bering Strait was flooded 10,000 years before the Last Glacial Maximum

Earth, atmospheric, and planetary sciences Correction for “The Bering Strait was flooded 10,000 years before the Last Glacial Maximum,” by Jesse R. Farmer, Tamara Pico, Ona M. Underwood, Rebecca Cleveland Stout, Julie Granger, Thomas M. Cronin, François Fripiat, Alfredo Martínez-García, Gerald H. Haug, and Daniel M. Sigman, which published December 27, 2022; 10.1073/pnas.2206742119 (Proc. Natl. Acad. Sci. U.S.A. 120, e2206742119).

The authors note that due to a production error, the vertical axis in Fig. 3B had been slightly offset from its correct position. The corrected figure and its legend appear below. Additionally, ref. 50 appeared incorrectly. The correct reference is M. L. Bender, Orbital tuning chronology for the Vostok climate record supported by trapped gas composition. Earth Planet. Sci. Lett. 204, 275–289 (2002). The online version has been corrected.

Fig. 3.

Western Arctic Ocean δ¹⁵N_N.p., global mean sea-level reconstructions and glacial isostatic adjustment simulation of Bering Strait relative sea-level history. (A) Western Arctic Ocean δ¹⁵N_N.p.; the dashed horizontal bar denotes maximum expected δ¹⁵N_N.p. for an exposed Bering Strait (Methods). Vertical error bars denote the larger of measured or long-term replicate δ¹⁵N_N.p. precision; horizontal error bars denote 68% quantiles (equivalent to ±1 SD) of the age-depth model. (B) GMSL from ICE-5G (19) (black), from an ice history constructed from the pre-LGM GMSL in ref. 18 (W02-derived, blue), and from ICE-PC (red). (C) Relative sea level at the Bering Strait from ice volume histories in (B), where ICE-PC RSL_BeSt is based on the intermediate Cordilleran Ice Sheet history (Materials and Methods). The black dashed line in (B) and (C) denotes modern sill depth of the Bering Strait (−53 m). Gray vertical shading denotes the timing of pre-LGM Bering Strait flooding reconstructed from panel (A). The colored bar at the bottom of (C) shows interpreted Bering Strait sea-level history. The brown vertical line denotes the reconstructed timing of Bering Strait closure in MIS 3; dashed brown lines are ±95% CIs (this study). The blue vertical line and dashes denote the mean timing and range of observations for postglacial Bering Strait flooding, respectively (8, 11, 12).
