Rapid deglaciation during the Bølling-Allerød Interstadial in the Central Pyrenees and associated glacial and periglacial landforms

Abstract

This is a PDF file of an article that has undergone enhancements after acceptance, such as the addition of a cover page and metadata, and formatting for readability, but it is not yet the definitive version of record. This version will undergo additional copyediting, typesetting and review before it is published in its final form, but we are providing this version to give early visibility of the article. Please note that, during the production process, errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain.

Geomorphological record of the glacial to periglacial transition from the Bølling–Allerød to the Holocene in the Central Pyrenees: the Lòcampo cirque in the regional context

“…2017, 2021b, 2022; Oliva et al . 2021). The cirque moraine preserved in the Lòcampo cirque was probably formed by a debris‐free glacier as it is significantly higher (~12–15 m) than the rock glacier ridges.…”

“…became entirely deglaciated, such as in Bacivèr cirque (Oliva et al . 2021). Similarly, in the surroundings of the Lòcampo cirque, the lowest polished bedrock surfaces in the Ruda Valley (1860 and 1900 m a.s.l.)…”

The timing of the deglaciation in the Atlantic Iberian mountains: Insights from the stratigraphic analysis of a lake sequence in Serra da Estrela (Portugal)

“…In particular, and given the current warming scenarios, it is imperative that the palaeoclimate community assesses the pace and dynamics of the last deglaciation to better evaluate environmental responses and strategies to adapt to current climate warming (IPCC, 2022). The use of different dating techniques on outcropping glacial deposits has conditioned the understanding of glacial stages in the Iberian mountains (Oliva et al, 2019(Oliva et al, , 2021. However, in regions where glacial records are scarce, such as western Iberia, sedimentological and environmental studies based on well-dated, high-resolution glacial lake records are key.…”

Holocene glacial oscillations in the Tyroler Valley (NE Greenland)

“…7.2–7.4 m sea level rise (Aschwanden et al 2019; Bamber et al 2013), and it is the only Northern Hemisphere ice sheet to have persisted during the last deglacial period. Fluctuations of the ice stored in the GrIS, as well as in the surrounding ice caps and mountain glaciers, promote a large‐scale redistributions of oceanic and atmospheric circulation patterns, sea‐level changes, redefinition of coastlines, shifts in land cover and ecosystems, and variations in greenhouse gas concentrations (Oliva et al 2021).…”
