51���� has initiated a new programme of mapping the seabed geology of the UK continental shelf, the first effort to consistently characterise the geology of the seabed in over 25 years.

The latest map offers new fine-scale digital maps featuring the seabed of offshore Yorkshire that contain combined bedrock, sediment, bedrock structure and geomorphology data. This is the third in a series of new, fine-scale maps to be released by BGS, with maps for offshore Anglesey and the Bristol Channel already available online.

The seabed geology maps are intended to support a diverse range of offshore activities and applications, including scientific research, offshore development, conservation efforts and marine management. It is part of a drive by BGS to develop new, fit-for-purpose geospatial products that, combined with the availability of new high-resolution data, can better meet current and future decarbonisation and marine science challenges. The maps are expected to be of interest to developers looking to deploy technology and infrastructure to create renewable energy.

The maps are based primarily on high-resolution bathymetry data collected through the Maritime and Coastguard Agency UK Civil Hydrography Programme. They are further informed by acoustic backscatter data, sediment cores and grab samples, seismic data, and existing onshore and offshore map products (both BGS mapsand publicly available academic and industry products).

The geological character of the seabed and shallow subsurface is often complex, but is not well captured by currently available resources.

By applying a consistent approach nationally, incorporating both classical and innovative mapping approaches, these map products offer a unique resource, providing an excellent insight into complex geology, as well as active environmental processes.

51���� is among other public and government organisations to have joined the  (UK CSM), helping to boost marine data and mapping standards. Improved geospatial resources will also provide important evidence for policy and decision makers, who need to consider the increasing demands placed on the marine environment from recreation, marine conservation and protection, resource development, and fisheries.

As well as providing important baseline datasets that can underpin efficiency in marine infrastructure projects, such as siting offshore renewables, the analysis and mapping process also leads to interesting new findings, providing the potential for genuine discovery.

The maps are available from BGS under the fine-scale maps section of the  and are designed to be viewed at 1:10 000 scale, or offline as downloadable shapefiles.

Other areas to be added as the mapping programme progresses include offshore Orkney, East Anglia, and further areas of offshore Wales.

Other maps in this series:

• Anglesey (Ynys Môn)
• Bristol Channel
