Responses of primary producers, anoxia, and chemical feedback to Late Glacial climate change: Insights from a paired lake approach

Journal of Quaternary Science, EarlyView.
Abstract Worldwide, lacustrine ecosystems are threatened by eutrophication and deoxygenation. Both processes are driven by the combined effects of human activities and climate change. Understanding the pre‐anthropogenic nexus between warming, eutrophication, deoxygenation, and related feedback is essential to determine how lakes respond to rapid ...

Ngarrawa (mound spring) sediments as archives of Holocene environmental change in arid central Australia: Insights from Itrax XRF scanning

Journal of Quaternary Science, EarlyView.
ABSTRACT Central Australia's ngarrawa, or ‘mound springs’, are unique hydrological systems that serve as some of the only near‐permanent sources of water and continuous sediment deposition in Australia's arid interior. As such, they hold significant potential as palaeo‐climate and ‐environmental archives in a region where many aspects of past climate ...

Global glacier mass change by spatiotemporal analysis of digital elevation models

Changement de masse des glaciers à l’échelle mondiale par analyse spatiotemporelle de modèles numériques de terrain Les glaciers de la planète rétrécissent rapidement, et produisent des impacts qui s'étendent de la hausse du niveau de la mer et la modification des risques cryosphériques jusqu'au changement de disponibilité en eau douce.

Mercury cycling during the last glacial period in Arctic Lake El'gygytgyn, NE Russia

Journal of Quaternary Science, EarlyView.
ABSTRACT Tectonic processes play a key role in the global mercury (Hg) cycle on geological timescales, by mobilising Hg from deep Earth reservoirs to the surface. These natural fluxes also introduce a dynamic component to the terrestrial Hg cycle that can interact with other environmental signals and influence Hg delivery to sedimentary records.

Carbon isotope geochemistry of organic matter in volcanic paleosols constrains paleo‐environmental variations

Journal of Quaternary Science, EarlyView.
ABSTRACT The Fiorano quarry paleosol developed within the Colli Albani volcanic district (Italy) in the time interval bracketed by the deposition of the Pozzolanelle pyroclastic‐flow unit (365 ± 4 ka) and the emplacement of the Capo di Bove lava flow (277 ± 2 ka).

First finding of Icelandic tephra in Czechia: Vedde Ash identified in palaeolake sediments of Stará Jímka

Journal of Quaternary Science, EarlyView.
ABSTRACT In this study, we report the first documented occurrence of the Icelandic Vedde Ash (VA) in the Bohemian Forest, identified within palaeolake sediments from Stará Jímka, Czechia, representing the first Icelandic tephra layer identified in Czechia.
