Title

Marine Environmental Mapping (MAREMAP) 1:10 000 scale bedrock map for Weymouth Bay, Dorset

Abstract

This is a 1:10,000 scale Bedrock geological map for some 800 km2 of the seabed across Weymouth Bay in Dorset. It joins seamlessly to the onshore BGS 1:10,000 scale Digital Geological Mapping (DiGMapGB-10) and therefore shows the coastal geology in detail. It comprises bedrock polygons, faults and limestone bed lines. The map was produced in 2015-16 by digitising against a seamless on- to offshore-shore elevation surface generated from high (1 m bin) resolution bathymetry and coastal Lidar data, collected as part of the Dorset Integrated Seabed Survey (DORIS) project and the Regional Coastal Monitoring Programme of England, made available by the Channel Coastal Observatory under the Open Government Licence. The map can be veiwed using the map viewer at www.bgs.ac.uk/research/marine/doris.html. This map has been produced under the auspices of the Marine Environmental Mapping Programme (MAREMAP), in collaboration between the BGS and the University of Southampton. The map itself should be referred to as: Westhead, R K, Sanderson, D J, Dix, J K. 2016. Bedrock map for the offshore Weymouth Bay area, with seamless coastal joint to BGS onshore (DiGMapGB-10) mapping. Bedrock Geology. 1:10 000 (Marine Environmental Mapping Programme, MAREMAP)

Lineage

The map was digitised at an effective 1:10,000 scale using BGS-Virtalis GeoVisionary 3D visualisation software and the BGS System for Integrated Geological Mapping (SIGMA). It was joined seamlessly to the onshore BGS digital geological mapping at the 1:10,000 scale (DiGMapGB-10) with an onshore overlap of 10’s to 100’s metres. It therefore supersedes DiGMapGB-10 in this overlap zone, which will be updated to allow for this in future versions. The surveying topography comprises a seamless elevation surface generated from stitched-together off-shore bathymetry and on-shore Lidar data obtained via the Channel Coastal Observatory (CCO; under the Open Government Licence) as part of the MAREMAP project – see www.maremap,ac,uk . The bathymetry dataset was collected under the Dorset Integrated Seabed Survey (DORIS) project - see www.dorsetwildlifetrust.org.uk. The on-shore Lidar was collected by the Environment Agency for the CCO as part of the Strategic Regional Coastal Monitoring Programme (England).
