A complete and easily accessible means of calculating surface exposure ages or erosion rates from 10Be and 26Al measurements
TLDR
In this paper, the authors present a single complete and straightforward method that reflects currently accepted practices and is consistent with existing production rate calibration measurements, which is intended to enable geoscientists, who wish to use cosmogenic-nuclide exposure age or erosion rate measurements in their work, to calculate exposure ages and erosion rates; compare previously published exposure ages on a common basis; and evaluate the sensitivity of their results to differences between published production rate scaling schemes.About:

Journal ArticleDOI
The Last Glacial Maximum.
Peter U. Clark,Arthur S. Dyke,Jeremy D. Shakun,Anders E. Carlson,Jorie Clark,Barbara Wohlfarth,Jerry X. Mitrovica,Steven W. Hostetler,A. Marshall McCabe +8 more
TL;DR: The responses of the Northern and Southern Hemispheres differed significantly, which reveals how the evolution of specific ice sheets affected sea level and provides insight into how insolation controlled the deglaciation.
Journal ArticleDOI
The last Eurasian ice sheets - a chronological database and time-slice reconstruction, DATED-1
TL;DR: In this paper, the authors present a new time-slice reconstruction of the Eurasian ice sheets (British-Irish, Svalbard-Barents-Kara Seas and Scandinavian) documenting the spatial evolution of these interconnected ice sheets every 1000 years from 25 to 10 years and at four selected time periods back to 40 years.
Journal ArticleDOI
Scaling in situ cosmogenic nuclide production rates using analytical approximations to atmospheric cosmic-ray fluxes
TL;DR: In this paper, a new scaling model based on analytical approximations to modeled fluxes of the main atmospheric cosmic-ray particles responsible for in situ cosmogenic nuclide production is proposed.

Geological calibration of spallation production rates in the CRONUS-Earth project
Brian Borchers,Shasta M. Marrero,Greg Balco,Marc W. Caffee,Brent M. Goehring,Nathaniel A. Lifton,Kunihiko Nishiizumi,Fred M. Phillips,Joerg M. Schaefer,John O. Stone +9 more
TL;DR: In this article, the authors describe a calibration procedure developed during the Cosmic-Ray Produced Nuclide Systematics on Earth (CRONUS-Earth) project and its application to an extensive data set that included both new cosmogenic nuclide samples and samples from previously published studies.
Journal ArticleDOI
Understanding Earth’s eroding surface with 10Be
Eric W. Portenga,Paul R. Bierman +1 more
TL;DR: In this article, the authors compile, normalize, and compare published 10Be erosion rate data (n = 1599) in order to understand how, on a global scale, geologic erosion rates integrated over 103 to 106 years vary between climate zones, tectonic settings, and different rock types.

TL;DR: In this paper, a new calibration curve for the conversion of radiocarbon ages to calibrated (cal) ages has been constructed and internationally ratified to replace IntCal98, which extended from 0-24 cal kyr BP (Before Present, 0 cal BP = AD 1950).

Cosmic ray labeling of erosion surfaces: in situ nuclide production rates and erosion models
TL;DR: In this paper, the authors present theoretical estimates of the production rates of isotopes of He, Ne and Ar based on available cross-section data, and discuss the implications of these parameters for single and multiple nuclide studies in terms of the erosion models considered.
Journal ArticleDOI
Air pressure and cosmogenic isotope production
TL;DR: In this article, it was shown that the cosmic ray flux increases at higher altitude as air pressure and the shielding effect of the atmosphere decrease, and that altitude-dependent scaling factors are required to compensate for this effect in calculating cosmic ray exposure ages.
