Modeling the statistical distributions of cosmogenic exposure dates from moraines
Patrick J. Applegate,Patrick J. Applegate,Nathan M. Urban,Benjamin J.C. Laabs,Klaus Keller,Richard B. Alley +5 more
TL;DR: In this paper, Monte Carlo-based models of moraine degradation and inheritance of cosmogenic nuclides were proposed to estimate the statistical distributions of exposure dates that we would expect to obtain from single moraines.
Journal ArticleDOI
Improved moraine age interpretations through explicit matching of geomorphic process models to cosmogenic nuclide measurements from single landforms
Patrick J. Applegate,Nathan M. Urban,Klaus Keller,Thomas V. Lowell,Benjamin J.C. Laabs,Meredith A. Kelly,Richard B. Alley +6 more
TL;DR: In this paper, a method for extracting moraine information by fitting geomorphic process models to observed exposure ages from single moraines is presented, which can help resolve controversies in exposure dating; the conclusions from two published studies based on their model fits.
Journal ArticleDOI
Large ensemble modeling of the last deglacial retreat of the West Antarctic Ice Sheet: comparison of simple and advanced statistical techniques
TL;DR: In this article, a 3D hybrid ice-sheet model is applied to the last deglacial retreat of the West Antarctic Ice Sheet over the last ǫ ∼ 20,000 years.
Journal ArticleDOI
A locally calibrated, late glacial 10Be production rate from a low-latitude, high-altitude site in the Peruvian Andes
Meredith A. Kelly,Thomas V. Lowell,Patrick J. Applegate,Fred M. Phillips,Joerg M. Schaefer,Colby A. Smith,Hanul Kim,Katherine C. Leonard,Katherine C. Leonard,Adam M. Hudson +9 more
TL;DR: In this article, the authors presented a locally calibrated Be-10 exposure-age dating rate for a low-latitude, high-altitude site near Quelccaya Ice Cap (similar to 13.95 degrees S, 70.89 degrees W, 4857 m asl) in the southeastern Peruvian Andes.
Journal ArticleDOI
Boulder height - exposure age relationships from a global glacial Be-10 compilation
Jakob Heyman,Patrick J. Applegate,Robin Blomdin,Natacha Gribenski,Jonathan M. Harbor,Jonathan M. Harbor,Arjen P. Stroeven +6 more
TL;DR: Cosmogenic exposure dating of glacial boulders is commonly used to estimate the timing of past glaciations because the method enables direct dating of the duration a boulder has been exposed to cos...
