Using Radon (222Rn) to Trace Variability in Greenhouse Gas Emission From Tree Stems Across Species, Seasons and Stem Heights

Ecohydrology, Volume 19, Issue 3, April/May 2026.
ABSTRACT Emissions from trees are an important component of the global methane (CH4) cycle, but their spatial origins (soil vs. in‐stem), transport pathways and environmental influences are not well constrained. To address these issues, this field study characterized spatial and temporal variability in stem emissions of biologically inert radon (222Rn),

Seasonal and Geologic Controls on Submarine Groundwater Discharge‐Derived Nutrient Fluxes to Two Coastal Embayments

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 4, April 2026.
Abstract Submarine groundwater discharge and porewater exchange are critical but often overlooked sources of nutrients to coastal systems. This study investigates how sediment permeability and summer‐winter seasonal dynamics influence the magnitude and biogeochemistry of nutrient fluxes from submarine groundwater discharge and porewater exchange ...

Isotopic evidence for enhanced tidal flat productivity driven by nutrient‐rich submarine groundwater discharge

Limnology and Oceanography, Volume 71, Issue 2, February 2026.
Abstract Submarine groundwater discharge (SGD) is well recognized as a significant nutrient source in coastal oceans. However, direct evidence linking SGD‐derived nutrients to biological production across trophic levels remains limited. Here, we investigated the influence of SGD on a tidal flat ecosystem on the west coast of Korea, where high ...

Pilot study of 222Rn and 226Ra activity concentrations in groundwaters of Roztocze region, Poland

E3S Web of Conferences, 2018
Authors selected 5 intakes of groundwaters outflowing from carbonate rocks in Roztocze region in Poland and measured activity concentrations of 222Rn and 222Ra. The average values of 222Rn and 226Ra activity concentrations were: 5.3 (min. 2.0, max.

Carbon Cycle Succession Across a Permafrost Thaw Gradient in Northeastern Alberta as Revealed by δ13C in Dissolved Solids, Gases, and Particulates in Lakes

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 2, February 2026.
Abstract δ13C in particulate organic carbon (POC), dissolved organic carbon (DOC), dissolved inorganic carbon (DIC), carbon dioxide (CO2(g)) and methane (CH4(g)), together with geochemical modeling, were applied to describe carbon cycle evolution in 40 boreal lakes situated across a permafrost thaw gradient in northeastern Alberta, Canada, where ...

Potential of Soils Natural Sorbents for Environmental Decontamination From 137Cs

Land Degradation &Development, Volume 37, Issue 2, Page 779-789, 30 January 2026.
ABSTRACT This study addresses the existing research gap concerning the lack of integrated data on the role of in situ soil components in the long‐term fixation of 137Cs under natural, protected, and non‐agricultural conditions. The contamination of ecosystems by radioactive isotopes, particularly 137Cs, represents a considerable environmental hazard ...
