Should we measure plutonium concentrations in marine sediments near Fukushima?
(Springer, 2013)
Pu contamination originating from Fukushima accident has not been detected in marine sediment samples collected outside a 30 km circle around the plant. It is shown, by means of numerical modelling, that if any impact ...

Modelling the environmental behaviour of pollutants in Algeciras Bay (south Spain)
(Elsevier, 2012)
An environmental study of Algeciras Bay is carried out through numerical modelling. First, a 2D barotrop ic model is applied to calculate tides and mean circulation. Results of this model are used by a sediment transport ...

Local scale marine modelling of Fukushima releases. Assessment of water and sediment contamination and sensitivity to water circulation description
(Elsevier, 2012)
The dispersion of 137Cs released from Fukushima nuclear power plant to the sea after the March 11th 2011 tsunami has been studied using numerical models. The 3D dispersion model consists of an advec tion/diffusion equation ...

Modelling the suspended matter dynamics in a marine environment using a three dimensional σ coordinate model: application to the eastern Irish Sea
(Elsevier, 2002)
A numerical model to study the suspended matter dynamics in the sea has been developed. The model solves the three dimensional hydrodynamic equations, that are written in normalized σ coordinates so that vertical resolution ...

Modelling the physico-chemical speciation of plutonium in the eastern Irish Sea: a further development
(Elsevier, 2002)
A numerical full three-dimensional model previously developed to simulate the physico-chemical speciation of plutonium in the eastern Irish Sea has been improved. The model solves simultaneously the hydrodynamic equations, ...

Influence of alongslope processes on modern turbidite systems and canyons in the Alboran Sea (southwestern Mediterranean)
(Elsevier, 2019)
This is an interdisciplinary study that combines morphoseismics, sedimentology and numerical modelling to elucidate at different scales of resolution the influence of alongslope processes on the turbidite systems (TSs) ...

Analysis of 236U and plutonium isotopes, 239,240Pu, on the 1 MV AMS system at the Centro Nacional de Aceleradores, as a potential tool in oceanography
(ScienceDirect, 2015-10-15)
The performance of the 1 MV AMS system at the CNA (Centro Nacional de Aceleradores, Seville, Spain) for 236U and 239,240Pu measurements has been extensively investigated. A very promising 236U/238U abundance sensitivity ...

The behaviour of Cs-137 in the North Atlantic Ocean assessed from numerical modelling: Releases from nuclear fuel reprocessing factories, redissolution from contaminated sediments and leakage from dumped nuclear wastes
(Elsevier, 2016)
A Lagrangian model which simulates the dispersion of 137Cs in the North Atlantic has been developed. The model includes water/sediment interactions. It has been tested comparing calculated and measured 137Cs concentrations ...
