TLDR
In this article, the authors used cosmic-ray exposure (CRE) dating to study deglaciation in a sector of the southern-central Pyrenees (the Panticosa massif and the upper Gallego and Ossau valleys).About:

Deglaciation history at the Alpine‐Mediterranean transition (Argentera‐Mercantour, SW Alps) from 10Be dating of moraines and glacially polished bedrock
Yann Rolland,Yann Rolland,Romain Darnault,Régis Braucher,Didier Bourlès,Carole Petit,S. Bouissou +6 more
TL;DR: In this paper, the authors estimate the extent and age of the last glacial maxima as well as the chronology of glacial recessions in various environmental contexts is key to source-to-sink studies and paleoclimate reconstructions.

Rapid deglaciation during the Bølling-Allerød Interstadial in the Central Pyrenees and associated glacial and periglacial landforms
Marc Oliva,Maria Rosário Fernandes,David Palacios,José M. Fernández-Fernández,Irene Schimmelpfennig,Dermot Antoniades,Georges Aumaître,Didier Bourlès,Karim Keddadouche +8 more
TL;DR: In this paper, the authors focus on the headwaters of the Garonne River, namely on the low-altitude Baciver Cirque (highest peaks at ~2600 m), with widespread erosive and depositional glacial and periglacial landforms.

Reversible glacial-periglacial transition in response to climate changes and paraglacial dynamics: A case study from Héðinsdalsjökull (northern Iceland)
David Palacios,Manuel Rodríguez-Mena,José M. Fernández-Fernández,Irene Schimmelpfennig,Luis M. Tanarro,José J. Zamorano,Nuria Andrés,Jose Úbeda,Þorsteinn Sæmundsson,Skafti Brynjólfsson,Marc Oliva,A.S.T.E.R. Team +11 more
TL;DR: In this paper, the authors used geomorphological analysis and mapping, glacier reconstruction and equilibrium-line altitude calculation, Cosmic-Ray Exposure dating (in situ cosmogenic 36Cl), and lichenometric dating to chronologically establish the origin of different glacial and rock glacier complex landforms deposited by Heðinsdalsjokull glacier.

Neoglaciation in the Spanish Pyrenees: a multiproxy challenge
TL;DR: This paper identified several colder periods during the mid and late Holocene: (i) the first phase of the Neoglacial period occurred at some time around 6-ka, (ii) a glacial pulse immediately before 3.4-ka; (iii) a re-advance during the Dark Ages, i.e., immediately before the Medieval Climate Anomaly, between the fourth and ninth centuries; and (iv) the Little Ice Age, which started at the beginning of the fourteenth century and finished in the mid-nineteenth century.
Late Quaternary ice sheet extents in northeastern Germany inferred from surface exposure dating
TL;DR: In this paper, the authors determined in situ cosmogenic 10-Be ages for 11 boulders on the Hoher Flaming ice marginal belt and five more on the Gerswalder moraine, a recessional moraine of the Pomeranian stage.

Journal ArticleDOI
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.
Journal ArticleDOI
A complete and easily accessible means of calculating surface exposure ages or erosion rates from 10Be and 26Al measurements
TL;DR: 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.

An outline of North American deglaciation with emphasis on central and northern Canada
TL;DR: In this paper, the authors present revised maps of North American deglaciation at 500-year and finer resolution, which represent an updating of a series prepared nearly two decades ago for the INQUA 1987 Congress.

TL;DR: In this article, an aliquot of highly enriched 10 Be master solution was serially diluted with increasing well-known masses of 9 Be and the specific activity was measured by means of accurate liquid scintillation counting (LSC).
