Deposition patterns of atmospheric 7Be, 210Pb, 40K in cost of west Mediterranean sea, Málaga (Spain) [PDF]

, 2016
The deposition of radionuclides on the ground is an essential process to understand atmospheric transportation, sedimentation and geological process, being the major removal pathway for airborne particulates.

Permafrost Thaw Dynamics Drive the Regime Shifts of Iron‐Bound Organic Carbon Sequestration in the East Siberian Arctic Shelf

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract In the changing Arctic, permafrost thaw is shifting from gradual to abrupt. Although iron‐bound organic carbon (OC‐FeR) critically modulates permafrost carbon‐climate feedbacks, its decadal‐scale variability and response to this regime shift remain poorly constrained.

Unravelling the plot: Co‐producing visualisations of palaeo‐data to improve their utility in conservation practice

Ecological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.
This study explores how typical palaeo‐data visualisations can hinder communication with conservation practitioners and other end users due to complexity, inaccessibility and unfamiliarity. Through a survey of palaeo‐researchers and presentation of two case studies, we highlight key barriers and demonstrate how collaboration with end users can improve ...

Environmental Controls on the Cycling of Fe and Mn in Patagonian Fjord Systems

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 1, January 2026.
Abstract Fjord sediments are important reservoirs and conduits of potentially bioavailable iron (Fe) and manganese (Mn). Both elements are critical to life, serving as key reactants in metabolic pathways, and play an important role in the reactivity and burial of organic carbon.

Long-term atmospheric fluxes of radionuclides at a coastal Mediterranean station [PDF]

, 2013
7Be is one of the radionuclide produced by spallation reactions of cosmic rays with light atmospheric nuclei. 7Be rapidly associates primarily with submicron-sized aerosol particles.

Analysis of Radon‐222 in Surface and Groundwater Sources in Kajiado County, Kenya

The Scientific World Journal, Volume 2026, Issue 1, 2026.
This study entailed measurement of the concentration of 222Rn in surface and subsurface water sources from Kajiado Municipality in Kenya. Kajiado County receives minimal rainfall and is not well covered by the municipal treated water network. The residents of the area mainly rely on subsurface water sources for their domestic consumption.

Datació de Posidonia oceanica mitjançant 210Pb

, 2021
La Posidonia oceanica és una fanerògama marina endèmica del Mediterrani. Es tracta d'una espècie molt important a les zones costeres, i en les últimes dècades la seva producció s'ha vist reduïda. En aquest estudi s'ha volgut demostrar la viabilitat d'utilitzar l'espècie Posidonia oceanica com a arxiu de contaminants al llarg del temps, alhora que s'han
