Journal ArticleDOI
Chronology of Taylor Glacier Advances in Arena Valley, Antarctica, Using in Situ Cosmogenic 3He and 10Be
Edward J. Brook,Mark D. Kurz,Robert P. Ackert,George H. Denton,Erik T. Brown,Grant M. Raisbeck,Françoise Yiou +6 more
TL;DR: In situ produced cosmogenic nuclides provide a new technique for constraining exposure ages of glacial deposits as mentioned in this paper, and the exposure ages appear consistent with the few previous age estimates, particularly with an isotope stage 5 age for Taylor II.
Journal ArticleDOI
A comparison of deep Antarctic ice cores and their implications for climate between 65,000 and 15,000 years ago
Jean Jouzel,Grant M. Raisbeck,J.P. Benoist,Françoise Yiou,C. Lorius,Dominique Raynaud,Jean-Robert Petit,Nartsiss I. Barkov,Y. S. Korotkevitch,V. M. Kotlyakov +9 more
TL;DR: In this article, the authors compared three deep ice cores for the main part of the last glacial period (from ca. 65,000-15,000 yr B.P.).
Journal ArticleDOI
129I from nuclear fuel reprocessing facilities at Sellafield (U.K.) and La Hague (France); potential as an oceanographie tracer
TL;DR: In this paper, the authors estimate that the amount of 129I (half-life 16 m.y.) transferred to the oceans from the nuclear fuel reprocessing facilities at La Hague, France and Sellafield, Great Britain during the past 25 years has been ~ 5 X 1027 atoms, or ~ 1.2 ton of the isotope.
Journal ArticleDOI
Estimation of slip rates in the southern Tien Shan using cosmic ray exposure dates of abandoned alluvial fans
Erik T. Brown,Didier Bourlès,Grant M. Raisbeck,Françoise Yiou,B. Clark Burchfiel,Peter Molnar,Deng Qidong,Li Jun +7 more
TL;DR: In this article, the relationship between cosmogenic nuclide content of individual clasts and the time since their deposition on a surface was assessed, and it was shown that very low 10 Be concentrations in material from active streambeds and at depth below one of the fan surfaces indicate that exposure prior to deposition onto fan surfaces was minimal.
Journal ArticleDOI
10 Be evidence for the Matuyama–Brunhes geomagnetic reversal in the EPICA Dome C ice core
TL;DR: Evidence is presented for enhanced 10Be deposition in the ice at 3,160–3,170 m, which is interpreted as a result of the low dipole field strength during the Matuyama–Brunhes geomagnetic reversal, which occurred about 780,000 years ago and provides a crucial tie point between ice cores, marine cores and a radiometric timescale.
