Century‐scale resilience of stored seagrass blue carbon

open access: yesLimnology and Oceanography Letters, Volume 10, Issue 6, Page 990-998, December 2025.
Abstract Blue carbon sequestration in coastal ecosystems is only relevant to climate change mitigation and carbon offset crediting if the carbon is taken out of circulation for at least a century. Here, we examined sediment cores, up to 2.2 m deep, collected in modern Zostera marina seagrass meadows in Mid‐Atlantic lagoons in Virginia, USA.

Atmospheric fluxes of radionuclides on monthly time-scale in Málaga (Spain) [PDF]

open access: yes, 2013
.- Bulk atmospheric deposition of gamma radionuclides ( 7Be, 210Pb and 40K ) has been measured at Málaga (4º 28´80′′ W; 36º 43′ 40′N) at a coastal Mediterranean station in the south of Spain, from January 2005 through December 2012 for monthly ...

Organic Carbon Fluxes on Seasonal to Decennial Timescales in Patagonia's Largest River‐Fjord System

open access: yesGlobal Biogeochemical Cycles, Volume 39, Issue 12, December 2025.
Abstract Fjord sediments are global sinks of organic carbon (OC), contributing to the long‐term storage of atmospheric CO2. Despite this recognition, the transfer and burial of OC in fjord sediments are still poorly quantified and suffer from a sampling bias toward distal environments where marine OC is dominant.

On the relativistic origin of the kink effect in the chain of Pb isotopes [PDF]

open access: yes, 2000
We investigate the origin of the kink effect (KE) in the relativistic mean field theory by transforming the single-particle Dirac equation into a Schrodinger-like equation.

Insights Into the Comprehensive Carbon Cycle in a Mangrove Ecosystem: A Case Study for Understanding Carbon Burial, Outgassing, and Outwelling in a Subtropical Island

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 130, Issue 12, December 2025.
Abstract A significant quantity of soil organic carbon (SOC) is buried in mangrove ecosystems. However, recent research has revealed that substantial amounts of carbon are exported to the atmosphere as CO2 or to the ocean as dissolved inorganic carbon (DIC), dissolved organic carbon (DOC), and particulate organic carbon (POC).

Sources and accumulation of 7Be, 210Pb and 137Cs isotopes in the annual needles of larch and cedar in Novy Urengoy region (Arctic part of Western Siberia) [PDF]

open access: yesE3S Web of Conferences, 2019
Annual needles of larch and cedar were sampled in the tundra zone of the Arctic part of Western Siberia in order to determine 7Be, 210Pb and 137Cs specific activities.

Dating of ice cores from Vernagtferner (Austria) with fission products and lead-210 [PDF]

open access: yes, 1982
Fission product (90Sr_ 90y, I37CS, total beta) and 2tOPb_210pO activities were measured in core samples from the temperate vernagtferner (3150 m altitude, Oetztal Alps, Austria).

Bioturbation experiments in the Venice Lagoon [PDF]

open access: yes, 2003
Short experiments (14–21 days) were carried out during autumn 1998 and spring 1999 at one selected site of the Venice Lagoon to measure bioturbation activities and mixing rates, as well as to obtain quantitative information on benthos functionality ...
