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 ...

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.

Review of the Salpausselkä ice‐marginal formations in Finland

Journal of Quaternary Science, EarlyView.
ABSTRACT Extensive Salpausselkä ice‐marginal formations were deposited in southern and eastern Finland during the Weichselian deglaciation. These comprise three major ridges (I, II, and III Salpausselkäs) and their eastern counterparts (Tuupovaara, Koitere, and Pielisjärvi), together forming laterally continuous ice‐marginal formations extending ...

The rise and fall of a volcanic plateau: Landscape evolution at the fringes of the former Patagonian Ice Sheet, Meseta Chile Chico, central Patagonian Andes

Journal of Quaternary Science, EarlyView.
ABSTRACT Understanding Earth‐surface processes along the fringes of large ice sheets is integral to deciphering cold‐region environmental variability and anticipating slope instability under climate change. We investigate the Meseta Chile Chico, a volcanic plateau in the central Patagonian Andes, located at the eastern margin of the former Patagonian ...

Late Quaternary lake filling and drying in northern Australia's largest freshwater lake

Journal of Quaternary Science, EarlyView.
ABSTRACT Lake Woods, Jurrkulu, is northern Australia's largest freshwater lake filled today in strong Indo–Australian summer monsoons (IASM) to maximum depths of ~5 m. On the western margins of the lake, two large arcuate ridges occur 20 to 40 m above the lake floor and inset within these are other mid‐elevation lake deposits, such as depositional ...

3D seismic imagery of a buried glacitectonic thrust complex in the North Sea and the dimensions of composite ridge systems in glaciated landscapes

Journal of Quaternary Science, EarlyView.
ABSTRACT Sets of sub‐parallel composite ridges in glaciated landscapes have long been regarded as landforms produced by glacitectonism, the brittle and ductile deformation of sediments at and immediately beyond glacier and ice‐sheet margins resulting from stresses produced by ice.

Silicon differentially protects PSII and PSI photochemistry and preserves fatty acid metabolism in salt‐stressed Sorghum bicolor (L.)

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Silicon (Si) has been demonstrated to be an important element to enhance crop tolerance against salinity. Nevertheless, mechanisms underlying Si's mitigation of salt stress remains insufficiently explored and understood. This study aims to provide new insights into Si's impact on salt‐stressed Sorghum bicolor (L.) supplied or not ...

Effect of sonication on European and Peruvian lupin flours: impact on the technological quality of gluten‐free breads and as a partial substitute for wheat

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND A widely cultivated pulse, lupin, has garnered interest for its beneficial nutritional properties, especially for baking applications. The harmful alkaloid content and poor functional properties of lupin limit its wider use. Sonication is an ecofriendly technology used to modify molecular structures.

Styrene and its natural analogues: accumulation and sustainable production methods

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Styrene, also known as vinyl benzene, is a colourless, highly volatile petrochemical that serves as a key monomer in the production of polystyrene and styrene‐butadiene rubber. Its industrial synthesis via the alkylation of benzene with ethylene relies on fossil fuels, requiring high temperatures and toxic catalysts that contribute to ...
