Abstract: The United Kingdom is the first country to systematically carry out seabed geological mapping, and its seabed geological mapping can be roughly divided into three stages. In the 1990s, the United Kingdom had basically completed the small and medium scale seabed geological mapping work in the continental shelf, and had initially achieved full coverage of 1: 50, 000 seabed geological mapping around 2010. In recent years, under the traction of the UK's Net Zero strategy, British Geological Survey has launched a new initiative of continental shelf seabed geological mapping program, and has successively released high-resolution, 10K scale seabed digital geological maps. The new maps innovates new concepts and methods such as multi-faceted characterization, two-part approach with descriptions of both ‘morphology’ and ‘geomorphology’, one-meter principle, which can effectively serve for offshore CCS developments and risk assessment, offshore renewable energy development, marine ecological management and spatial planning. Drawing on the UK’s seabed mapping initiative, China's seabed geological mapping in the new period should strengthen the top-level design, unify the organization and implementation of the national Marine regional geological survey, innovate the mapping concept, change the mapping path, upgrade the technical means, optimize the expression form, and effectively serve for carbon peaking and carbon neutrality goals.
