Journal ArticleDOI
The half-lives of uranium-234 and thorium-230
Hai Cheng,Richard Lawrence Edwards,J.A. Hoff,Christina D. Gallup,David Richards,Yemane Asmerom +5 more
TL;DR: In this article, the authors used high precision thermal ionization mass spectrometric (TIMS) methods to determine the half-life of zircons with concordant 238 U/ 238 U and 230 Th / 238 U atomic ratios.
Journal ArticleDOI
Rapid sea-level fall and deep-ocean temperature change since the last interglacial period
K. B. Cutler,Richard Lawrence Edwards,Frederick W. Taylor,Hai Cheng,Jess F. Adkins,Christina D. Gallup,P.M Cutler,George S. Burr,Arthur L. Bloom +8 more
TL;DR: In this article, the authors used both 230 Th and 231 Pa dating techniques as a test of age accuracy to date Huon Peninsula, Papua New Guinea and Barbados corals formed at times since the Last Interglacial Period.
Journal ArticleDOI
The timing of high sea levels over the past 200,000 years.
TL;DR: The 230Th ages and 234U/238U ratios were determined for Barbados corals that grew during periods of high sea level within the last 200,000 years and support the idea that glacial-interglacial cycles are caused by changes in Earth's orbital geometry.
Journal ArticleDOI
A penultimate glacial monsoon record from Hulu Cave and two-phase glacial terminations
Hai Cheng,R. Lawrence Edwards,Yongjin Wang,Xinggong Kong,Yanfang Ming,Megan J. Kelly,Xianfeng Wang,Christina D. Gallup,Weiguo Liu +8 more
TL;DR: Oxygen isotope records of three stalagmites from Hulu Cave, China, extend the previous high-resolution absolute-dated Hulu Asian Monsoon record from the last to the penultimate glacial and deglacial periods as discussed by the authors.
Journal ArticleDOI
Direct determination of the timing of sea level change during termination II.
TL;DR: This paper used combined 230Th and231Pa dating to determine that corals grew 135.8 ± 0.8 thousand years ago, indicating that sea level was 18 ± 3 meters below present sea level at the time.
