A Needle in a Haystack: Landscape Survey and Archaeological Detection Experiments in Apalachee Bay

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT This paper presents the results of a pilot landscape‐scale seismic survey undertaken in Apalachee Bay, Florida, across a submerged landscape that contains dozens of Pre‐Contact sites. In addition to the goals of improving the geophysical and remote sensing ground model for this submerged landscape, the survey also sought to undertake the first

Aeolization on the Atlantic coast of Galicia (NW Spain) from the end of the last glacial period to the present day: Chronology, origin and evolution of coastal dunes linked to sea‐level oscillations

open access: yesEarth Surface Processes and Landforms, Volume 48, Issue 1, Page 198-214, January 2023., 2023
The Atlantic coast of NW Spain, where shingle beaches appear today, has suffered an important mobilization of dunes from a sea level about −120 m (bpsl), 20 ky ago. This aeolization caused the collapse of coastal/fluvial ecosystems (as forests) until the Late Holocene.

Geochemical and Documentary Topography of a Medieval Silver Valley: Detection of Workshops and Identification of Their Function

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT This paper presents the interdisciplinary investigation (archaeology, geochemistry, history) of a medieval silver and lead production site located in southern France, in the Minier valley (Occitanie, Aveyron, Le‐Viala‐du‐Tarn). In order to identify the production sites, in situ geochemical surveys were carried out using a portable X‐ray ...

Linking uplift, erosion, and sedimentation using landscape evolution models: Madagascar since the Late Cretaceous

open access: yesEarth Surface Processes and Landforms, Volume 48, Issue 1, Page 215-229, January 2023., 2023
This paper uses a numerical landscape evolution model to reconstruct the topographic history of Madagascar since the Late Cretaceous. The model is optimised by balancing the volumes of onshore erosion and offshore sedimentation; the former is predicted with erosion laws and based on uplift history inferred from elevated planation surfaces.

Increasing Redox Potential of Pyromellitic Diimide by Chemical Modifications: Toward High‐Voltage Organic Positive Electrode for Lithium Battery

open access: yesBatteries &Supercaps, EarlyView.
Chemical modifications of soluble pyromellitic diimide derivatives with bromo‐ and cyano‐ electron‐withdrawing groups instead of hydrogen lead to an increase of redox potential of 210 and 420 mV respectively compared to the reference. Lithium batteries are considered as the most promising electricity storage solution to support the energy transition ...

Divergence and introgression among the virilis group of Drosophila

open access: yesEvolution Letters, Volume 6, Issue 6, Page 537-551, December 2022., 2022
Abstract Speciation with gene flow is now widely regarded as common. However, the frequency of introgression between recently diverged species and the evolutionary consequences of gene flow are still poorly understood. The virilis group of Drosophila contains 12 species that are geographically widespread and show varying levels of prezygotic and ...

The spatial variation of Asian dust and marine aerosol contributions to glaciochemical signals in central Asia [PDF]

open access: yes, 1992
Short-term (6 months to 17 years) glaciochemical records have been collected from several glacier basins in the mountains of central Asia. The spatial distribution of snow chemistry in central Asia is controlled by the influx of dust from the large ...
