Features in Liverpool Bay plotted from 3D data

Integration, analysis and contextualisation

The 2D line data was processed in GIS to show the time/ depth attributes

for both Bristol Channel and Liverpool Bay study areas, to show general

trends in the data to complement the individual features identified.

All the data was then used to interpret the

courses of palaeochannels and past

coastlines

Characterising the submerged landscape and understanding its archaeological and palaeo-environmental significance

Historic Landscape Character Areas

Colours showing the level archaeological and palaeo-environmental significance associated with particular types of landscape dark=high pale=low

An extensive area taking in the whole ofwhat is now Carmarthen Bay and alsoland lying off the south Pembrokeshirecoast. It would have been relatively highground for much of the later Palaeolithicand Mesolithic, bounded by a river valleyto the south. It would have been aseasonal hunting/gathering area, andthere is a possibility that artefacts andenvironmental deposits survive in thisarea. There are also possibly submergedcaves in this area. This area has beendefined from extrapolated 2D data, andthus although its general character iscorrect, it has not been possible toidentify individual landscape features.

Management Areas

Very High. This is an area where landscape featuresand deposits containing archaeological andenvironmental information have been demonstratedto survive. It is therefore advised that wherepossible these deposits are preserved in situ.

Medium. An area defined only by extrapolated 2Ddata. It is likely that deposits containingarchaeological and environmental informationsurvive, but available data does not conclusivelydemonstrate this. More detailed data, in particular3D data, may need to be collected if detailedguidance is required for this area.
