  • Assessment of Tc-99 monitoring within the western Irish Sea using a numerical model 

    Olbert, Agnieszka Indiana; Hartnett, Michael; Dabrowski, Tomasz (Elsevier ScienceDirect, 2010-05-26)
    Water circulation patterns and associated material transport within a highly dynamic system such as the Irish Sea are complex phenomena. Although Tc-99 monitoring programme undertaken by the Radiological Protection Institute ...
  • Cyclonic circulation in the western Irish Sea in future climate 

    Olbert, Agnieszka Indiana; Hartnett, Michael; Dabrowski, Tomasz (International Association for Hydro-Environment Engineering and Research, 2011-07-01)
    The Irish Sea (IS) is a semi-enclosed body of water on the European Continental Shelf and the Western Irish Sea Gyre (WISG) is a characteristic phenomenon of the Sea. The gyre due to its significant effects on the circulation, ...
  • Determination of flushing characteristics of the Irish Sea: A spatial approach 

    Dabrowski, Tomasz; Hartnett, Michael T.; Olbert, Agnieszka Indiana (Elsevier ScienceDirect, 2011-12-08)
    The Authors devised a novel generic approach to assessing the flushing of the Irish Sea through the determination of spatially distributed residence times and the development of flushing homogeneity curves. Results indicate ...
  • Effects of complex hydrodynamic processes on the horizontal and vertical distribution of Tc-99 in the Irish Sea 

    Olbert, Agnieszka Indiana; Hartnett, Michael; Dabrowski, Tomasz (Elsevier ScienceDirect, 2010-10-14)
    The increased discharge of Tc-99 from the Sellafield plant following the commissioning of the Enhance Actinide Removal Plant in 1994 was reflected in higher Tc-99 activity concentrations over much of the Irish Sea The ...
  • Influence of seasonal circulation on flushing of the Irish Sea 

    Dabrowski, Tomasz; Hartnett, Michael T.; Olbert, Agnieszka Indiana (Elsevier ScienceDirect, 2009-12-16)
    We applied a three-dimensional general ocean and coastal circulation model to the Irish Sea in order to determine water renewal time scales in the region. The model was forced with meteorological data for 1995, a year with ...
  • Long-term inter-annual variability of a cyclonic gyre in the western Irish Sea 

    Olbert, Agnieszka Indiana; Hartnett, Michael; Dabrowski, Tomasz (Elsevier ScienceDirect, 2011-05-26)
    The western Irish Sea gyre (WISG) is a cyclonic baroclinic flow around a dome of stagnant water which develops each year during the heating season in the western Irish Sea. Research was carried out to determine long-term ...
  • Modelling phytoplankton dynamics in a complex estuarine system 

    Nash, Stephen; Hartnett, Michael; Dabrowski, Tomasz (2011)
    The primary objective of this research was to develop a generic methodology for numerical modelling of the water quality within estuarine systems; in particular, this research focused on modelling nutrient dynamics and ...
  • Regional modelling of the 21st century climate changes in the Irish Sea 

    Olbert, Agnieszka Indiana; Dabrowski, Tomasz; Nash, Stephen; Hartnett, Michael (Elsevier, 2012-06)
    An assessment of the complex evolution of climate change signals in the Irish Sea over the 21st century is presented in this paper. Potential impacts of climate change on the local hydrography are explored and interrelationships ...
