Soil, grain and water chemistry and human selenium imbalances in Enshi district, Hubei Province, China [PDF]

, 1996
Many elements which are essential to human and other animal health in small doses can be toxic if ingested in excess. Selenium (Se), a naturally occurring metalloid element is found in all natural materials on earth including rocks, soils, waters, air,

Sustaining Science Infrastructure Is Difficult; Is Commercialization the Answer? The USA National Phenology Network's Experience

Perspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract Biological and physical science infrastructure programs play a critical role in supporting scientific discovery. Even with their foundational roles in the process of science, frequently, support for these programs is threatened, reduced, or eliminated, placing critical data and information at risk of interruption or loss.

The role of data modelling in a modern geological survey [PDF]

, 2015
Data models are key elements in understanding the meaning (semantics) of data and communicating the information requirements for geoscientific-environmental research. The British Geological Survey (BGS) models its data to provide an understanding of: the

Common Sensor Platform Project

Perspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract EarthScope Consortium's Common Sensor Platform (CSP) project is a unified, modular, and scalable design approach for geophysical instrumentation deployments. Developed through cross disciplinary collaboration of National Science Foundation's GAGE and SAGE facilities, the platform outlines core station subsystems that have the flexibility to be

Tracing the origin of Roman mosaic tiles in Aquileia: Petrographic analysis of specimens from the suburbium

Archaeometry, Volume 67, Issue 5, Page 1247-1266, October 2025.
Abstract This research represents the most extensive characterisation of Roman mosaic tesserae (tiles) from Aquileia, Italy, to date, examining 153 specimens. The study aimed to identify the lithotypes used in mosaics production through a multi‐analytical approach, which included colorimetric analysis, polarised light microscopy and scanning electron ...

A multidisciplinary study on the location of Roman sites in the southern sub‐plateau of the Iberian Peninsula

Archaeometry, Volume 67, Issue 5, Page 1373-1390, October 2025.
Abstract Architectural and engineering elements of the Roman civilization constitute an important cultural heritage. Nevertheless, not all ancient Roman cities and the roads connecting them have been found, mainly because classical geographical sources show a significant lack of precision.

Sensitivity of Earth's Radiation Budget to Lower Boundary Condition Data Sets in Historical Climate Simulations

Geophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract Atmospheric general circulation models are important tools to study climate change. A routine vindication for these models is to compare simulations with prescribed historical sea surface temperature (SST) and sea ice (SI) fraction against observations.

Oligocene to Miocene Topographic Inversion and Accelerated Uplift of Southern Tibet Revealed by the Paleodrainage Evolution of Intermontane Basins

Geophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract The uplift history of the Gangdese arc in Southern Tibet is fundamental to understanding when and how the plateau attained its current elevation and topographic relief. Detrital multi‐mineral provenance analysis of the Oligocene–Miocene strata in the intermontane Wuyu Basin provides new key information on the paleodrainage evolution in ...
