Loess Studies in Aotearoa New Zealand
Loess in Aotearoa New Zealand (ANZ) has been studied since its first documented recognition (on Banks Peninsula) in 1878 by Julius von Haast. A decade later, John Hardcastle revealed that southern ANZ loess was both glacial in origin and contained signals of past climates.

. Sediment transport activities in the periglacial environment are controlled by hillslopes micrometeorological conditions (i.e., air and ground temperatures, ground water content), which are highly affected by vegetation cover.

Seismic imaging of the critical zone of dolerite dykes at Cap Fréhel in Brittany (France)
Abstract In June 2023, we measured ten near‐surface seismic profiles to image the critical zone of dolerite (diabase) dykes that cut the sandstone at Cap Fréhel in Brittany (France). Seismic ray tracing and inversion are used to determine the thickness of the regolith layer from first‐arrival P‐wave traveltimes.

Impacts des processus périglaciaires sur la préservation des ossements
This paper deals with faunal remains destruction due to frost/thaw cycles in natural environment during four years. For this study, different types of bones were used (fresh bones, dry bones, burned as well as fossil bones).

Abstract Degradation of Arctic permafrost due to global warming and sea level rise could trigger positive feedbacks, exacerbating climate change. However, uncertainties remain on how permafrost systems may respond because we lack a complete understanding of the permafrost‐climate feedback.

Exploring Potential Mechanisms for the Initiation of Solifluction Patterns
Abstract Hillslopes in arctic regions commonly display large‐scale features—known as solifluction patterns—that form due to the exceedingly slow downhill movement of frost‐heaved soil. Here we use a combination of remote sensing data, linear stability analysis, numerical modeling, and review of a wide range of literature to evaluate several working ...

Abstract High‐altitude wetlands are critical ecosystems that store water, regulate downstream flows, and sustain biodiversity. Their persistence is tightly linked to continuous water inputs from precipitation, groundwater, snow and glacier melt, making them highly vulnerable to climate‐driven shifts in mountain hydrology. Rapid glacier retreat, altered

Data analysis treatment of measurements of displacement flows in a high mountain periglacial environment [PDF]
We have measured the movements of several hundred superficial pebbles in a high mountain periglacial environment: the high valley of Chambeyron (Alpes de Haute-Provence).

Abstract The use of stone hammers to produce sharp stone flakes—knapping—is thought to represent a significant stage in hominin technological evolution because it facilitated the exploitation of novel resources, including meat obtained from medium‐to‐large‐sized vertebrates. The invention of knapping may have occurred via an additive (i.e., cumulative)
