The Zanclean megaflood of the Mediterranean – Searching for independent evidence
(Elsevier, 2020)
About six million years ago, the Mediterranean Sea underwent a period of isolation from the ocean and widespread salt deposition known as the Messinian Salinity Crisis (MSC), allegedly leading to a kilometer-scale level ...

Estudio arqueoastronómico de las iglesias de la Asunción en los poblamientos cristianos tras la reconquista de las provincias de Córdoba y Soria
(Real Academia de Córdoba, 2020)
Estudiamos la orientación de las iglesias de la Asunción en Soria (N=73). El grupo del románico de repoblación (N=45, siglos XII-XIII) muestra patrones de orientación solar: 47% de las iglesias se alinean con el sol ...

Environmental radioactivity and trace metals in surficial sediments from estuarine systems in Ghana (Equatorial Africa), impacted by artisanal gold-mining
(Elsevier, 2020)
This paper reports concentrations of γ-emitter radionuclides (40K, 137Cs, 210Pb, 226Ra, 228Ra, 228Th and 234Th) and some metals (Al, Cr, Fe, Co, Ni, Cu, Zn, As, Sr, Cd, Sb, Cs, Pb, Th and U) in surficial sediments from ...

Modelling the kinetic reactive transport of pollutants at the sediment-water interface. Applications with atmospheric fallout radionuclides
(Elsevier, 2022)
Understanding the behaviour of particulate matter and chemicals at the sediment-water interface (SWI) is of interest in environmental studies and risk assessments. These processes are still poorly understood, and this work ...

Depth-distributions and migration of fallout radionuclides in mountain soils from Chr´ea National Park (Algeria): The role of rhizospheres
(Elsevier, 2022)
The distribution and migration of artificial fallout radionuclides in natural soils has been profusely studied for assessing radioecological impacts and predicting their long-term behaviour, among other topics. Despite the ...

Environmental radioactivity in a sediment core from Algiers Bay: Radioecological assessment, radiometric dating and pollution records
(Elsevier, 2020)
The sedimentary system of the Algiers Bay has been impacted in the last decades by the exponential increases in population, urbanism and industrial activities of the city of Algiers, and by episodic floods, mudflows, ...

Multimodal-TERESA, a 210Pb-based radiometric dating model for recent sediments under largely varying rates of supply
(Elsevier, 2020)
Lead-210 from natural atmospheric fallout is widely used in multidisciplinary studies for dating recent sediments. In anthropogenically-impacted and/or high energy systems the 210Pb flux onto the sediments may show non-random ...

Fine-tuning of Pb-210-based methods for dating vegetated saltmarsh sediments
(Elsevier, 2021)
Saltmarshes, wetlands, inter-tidal mudflats are highly productive natural ecosystems with significant ecological value. 210Pb and 137Cs have been used for establishing chronologies at a centennial scale in these sediments. ...

Assessment of metal levels and pollution indices of the Songor Wetland, Ghana
(Elsevier, 2021)
Sediment, soil and fish samples collected from the Songor Wetland were assessed for the spatial distributions of metal (Al, Fe, Zn, Cr, Ni, Cu, Pb, As, Cd and Hg) levels and contamination loads, using pollution indices ...

On the use of 210Pb-based records of sedimentation rates and activity concentrations for tracking past environmental changes
(Elsevier, 2022)
Lead-210 from natural atmospheric fallout is widely used in multidisciplinary studies to date recent sediments. Some of the 210Pb-based dating models can produce historical records of sediment accumulation rates (SAR) and ...
