The missing woodland story: Implications of 1700 years of stand‐scale change on ‘naturalness’ and managing remnant broadleaved woodlands

People and Nature, EarlyView.
Abstract Longer‐term perspectives—equivalent to the lifespans of long‐lived trees—are required to fully inform perceptions of ‘naturalness’ used in woodland conservation and management. Stand‐scale dynamics of an old growth temperate woodland are reconstructed using palaeoecological data.

Radioactivity and measurements of sediment deposition rate of the Drenova reservoir (B&H) [PDF]

Nuclear Technology and Radiation Protection, 2012
This work presents the first estimate of the radioactivity and sediment deposition rate of the Drenova reservoir. The radioactivity and sedimentation rate were computed applying the 210Pb and 137Cs methods.

A Multi‐Analytical Approach for the Compositional Characterization and Chronological Discrimination of Benin (Nigeria) Metal Sculptures

Archaeometry, EarlyView.
ABSTRACT This study presents a multi‐analytical archaeometric approach for the compositional characterization and chronological discrimination of Benin metal sculptures in relation to the 1897 Punitive Expedition. The methodology integrates elemental composition (XRF and ICP), stable lead isotope ratios (MC‐ICP‐MS) for alloy system characterization ...

A Temporally Consistent Spatial Gradient in Methane Ebullition From a Eutrophic Lake

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract Gas bubble emission (ebullition) from lake sediment is a prominent source of the greenhouse gas methane (CH4) to the atmosphere, but the stochastic nature of bubble release and thus high variability in space and time makes the estimation of lake CH4 ebullition challenging.

Baseline measurements of 210Po and 210Pb in the seafood of Kasimedu fishing harbour, Chennai, South East Coast of India and related dose to population

Environmental Chemistry and Ecotoxicology, 2019
The Bioaccumulation studies of natural radionuclides such as 210Po & 210Pb was carried out to explain the radiation levels of Kasimedu fishing harbour, Chennai, southeast coast of India. Abiotic components like water, sediment and biotic components (Fish

210Pb Ingestion in Akita City, Japan.

RADIOISOTOPES, 1992
Ingestion of 210Pb in Akita City, northern Japan was studied with food category samples and total diet samples by means of a low energy photon spectrometry. Results for food category samples revealed that the contribution of marine products to total 210Pbingestion was the largest.

Organic Carbon Burial Rates in Muddy Temperate Shelf Sea Sediments

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract Muddy continental shelf sediments act as important sinks for atmospheric CO2 by accumulating organic matter, a small fraction of which is buried and stored as organic carbon (OC) over long timescales. Quantifying long‐term OC burial in shelf sediments is critical for understanding their role in climate regulation; however, this remains ...

Atmospheric radioactive nuclide deposition on the coast of the Maowei Sea, northern Beibu Gulf, China

Frontiers in Marine Science, 2023
The natural radioisotopes 7Be, 210Pb, and 210Po, with different half-lives, are all particle-reactive and serve as natural tracers to study sources and transportation of sediments, sedimentation rates, and sediment chronology.
