Managing and visualising geochemical data for tephra correlation with the IntChron Integration Tool

Journal of Quaternary Science, EarlyView.
ABSTRACT There is now a wealth of glass‐shard geochemical data for volcanic ash (tephra) layers from a wide range of volcanoes and eruptions, providing invaluable datasets for tephrochronology. However, compilation of published data to assess tephra correlations leads to large files and requires careful management.

Stable isotope analysis of freshwater gastropod carbonates from Swanscombe: Insights into climate stability and seasonality during MIS 11c

Journal of Quaternary Science, EarlyView.
ABSTRACT Stable isotope analyses of freshwater mollusc carbonate can record environmental conditions at the time of mineralisation, yet this technique remains underused in British Middle Pleistocene fluvial sequences, despite the abundance of fossil shell material in these deposits.

New Schmidt hammer exposure‐age dating calibrations for the Last Glacial Termination in NW Scotland: Development and application to undated Torridon Group sandstone surfaces in Wester Ross

Journal of Quaternary Science, EarlyView.
ABSTRACT An understanding of the terrestrial extent, retreat dynamics and climate–glacier coupling of ice masses during the Last Glacial Termination (LGT, ~18–11 ka) is often limited by a fragmentary geomorphological record and is dependent on precise, accurate and robust dating frameworks.

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 ...

In vitro and in sacco determination of neutral detergent fibre digestibility of treated cereal straw

JSFA reports, EarlyView.
Abstract Background Cereal straw is hardly digestible due to its complex bonds of lignin, cellulose and hemicellulose. That is why chemical treatments, such as with sodium hydroxide, may help to loosen the bonds and thus increase ruminal digestibility. Neutral detergent fibre (NDF) digestibility is a good predictor of feed intake.
