    West Coast Palaeolandscapes (2 of 2) West Coast Palaeolandscapes (2 of 2) Presentation Transcript

    • Features in Liverpool Bay plotted from 3D data
    • Integration, analysis and contextualisationThe 2D line data was processed in GIS to show the time/ depth attributesfor both Bristol Channel and Liverpool Bay study areas, to show generaltrends in the data to complement the individual features identified.
    • Integration, analysis and contextualisation All the data was then used to interpret the courses of palaeochannels and past coastlines
    • Integration, analysis and contextualisation The digitised features identified in the 3D surveys were exported from Kingdom into a GIS compatible format
    • Generation of Relative Topographic Maps
    • Generation of Relative Topographic MapsLate Palaeolithic Early Mesolithic Middle Mesolithic

    • Management and disseminationMaking the results of the study accessible to allIdentified audiences include:- • Strategic Planners • Aggregates Industry • Archaeologists • Local Communities • Schools
    • Project Products and Outputs • Technical study report – academic publication available on-line • Popular booklet – hard copy circulation and digital copy internet accessibility • Web-site – A colourful and attractive site with links to a whole range of on-line related resources • Education packs – available on-line for schools developed to provide teachers and children with independent learning opportunities • Exhibition - Talks and presentations to local community groups across Wales undertaken by the Welsh Archaeological Trusts, PCNPA and RCAHMW • Integration of results into Regional Historic Environment and National Maritime Records
    • A Management ToolBenefits of a management tool:- • Provides a framework on which to build future understanding • Focuses future investigation • Enables more informed decision making • Informs strategic plans • Guides future conservation and protection • Guidance future activity and development
    • Future Threats:- • Off-shore mineral extraction Aggregates Dredging • Renewable energy production • Oil and Gas prospection and extraction • Pipelines and Cables • Etc.
    • Characterising the submerged landscapeand understanding its archaeological andpalaeo-environmental significanceHistoric Landscape Character AreasColours showing the level archaeological and palaeo-environmental significance associated with particular types oflandscape dark=high pale=low
    • Historic Landscape Area DescriptionsExample An extensive area taking in the whole of what is now Carmarthen Bay and also land lying off the south Pembrokeshire coast. It would have been relatively high ground for much of the later Palaeolithic and Mesolithic, bounded by a river valley to the south. It would have been a seasonal hunting/gathering area, and there is a possibility that artefacts and environmental deposits survive in this area. There are also possibly submerged caves in this area. This area has been defined from extrapolated 2D data, and thus although its general character is correct, it has not been possible to identify individual landscape features.
    • Management AreasColour shading shows the historic environment significance ofeach area dark= high pale=lowFuzzy edged areas
    • Management Area Information andstatements of significanceExamples Very High. This is an area where landscape features and deposits containing archaeological and environmental information have been demonstrated to survive. It is therefore advised that where possible these deposits are preserved in situ. Medium. An area defined only by extrapolated 2D data. It is likely that deposits containing archaeological and environmental information survive, but available data does not conclusively demonstrate this. More detailed data, in particular 3D data, may need to be collected if detailed guidance is required for this area.
