Offshore seismic hazard models and maps for the UK Exclusive Economic Zone

A new, robust seismic hazard model and seismic hazard maps for the UK offshore Exclusive Economic Zone using the latest available data and recent advances in seismic hazard methodology and a Monte Carlo-based approach for probabilistic seismic hazard analysis. These are intended to update the current maps for UK waters published in 2002. We developed a comprehensive catalogue of earthquake activity across the region by combining existing earthquake catalogues and data from regional and local monitoring agencies. We modelled earthquake occurrence across the region using a seismic source characterisation (SSC) model that consists of a series of zones, where seismicity is considered to be homogeneous, based on tectonics, geology and seismicity of the study area. We use four different seismic source zone models within the SSC to capture the epistemic uncertainty in different rupture scenarios. A logic tree approach was used to account for the epistemic uncertainty in earthquake activity rates, maximum magnitude, earthquake depth distribution, and faulting style. Ground motions are estimated for different rupture scenarios using a ground motion characterisation (GMC) model that consists of five multiple ground motion prediction equations considered to be applicable to the region. The GMPEs are included in a logic tree where the weights are informed by the fit between observed and modelled ground motions. The GMC model also includes the host-to-target adjustments and a single-station sigma model. Hazard is calculated at 4585 individual points spaced at 0.125° in latitude and 0.25° in longitude for peak ground acceleration (PGA) and spectral acceleration at 0.2 s (SA0.2 s) and 1.0 s (SA1.0 s) for 5% damping and rock conditions and the return periods of 95, 475, 1100, 2475, and 5000 years. This is the first time that maps of the seismic hazard at short (0.2 s) and long periods (1.0 s) have been produced for UK waters. Hazard curves, uniform hazard spectra, and disaggregation analysis have been calculated for three offshore carbon capture and storage sites (Endurance, Acorn, and HyNet North West). New offshore hazard maps for the UK waters will support UK decarbonisation by providing owners and operators of offshore structures with robust estimates of seismic hazard for new and existing sites. The results will also inform regulatory decisions to ensure safe operating practices in the industry and help identify areas of higher hazard where further site-specific studies might be needed. Finally, it will provide a robust baseline for tectonic seismic activity in the North Sea that can be used to help discriminate any seismicity induced by operations, such as CCS, in the event it occurs. The technical report by Mosca et al. (2024), which provides a detailed description of the methods and results, together with the project’s products, can be found in (http://www.earthquakes.bgs.ac.uk/hazard/UKhazard.html).

Laser ablation trace element analyses of rutile and apatite grains from the Zambian Copperbelt

Laser ablation trace element data for rutile and apatite were recovered from Mindola and Nchanga. At Mindola the Kitwe Formation is the major host to Cu-Co (copper-cobalt) mineralisation at Nkana-Mindola, particularly within the Ore Shale member. The Ore Shale has been subdivided into multiple units based on texture and composition. In summary, a black shale or dolomitic siltstone. often with a schistose or banded texture, passes upwards into a coarser porous sandstone or siliceous dolomite and capped by a massive argillite. Mineralisation across Nkana-Mindola is primarily hosted by dolomitic siltstones, pyritic black shales and schists. At Nchanga samples were analysed from the upper and lower ore bodies hosted within the Lower Roan metasediments which unconformably overlie the basement, transitioning from basal continental, arenaceous clastic rocks to shallow marine argillaceous clastic rocks and mixed platform carbonates.

U-Pb geochronology data for carbonates from the Neuquen Basin, Argentina

U-Pb (Uranium-Lead) geochronology data for carbonates from the Nequen Basin Argentina. Data was collected for a series of Copper (Cu) deposits: Los Chihuidos, Barda González, La Cuprosa, El Porvenir and Tordillos Cu deposits. The Los Chihuidos deposit contains calcite either as individual calcite grains or as sparry, calcite cement in a red calcareous sandstone. The Barda Gonzales samples were recovered from a well sorted sandstone. The calcareous litharenite from the Huincul Formation at El Porvenir is well-sorted, texturally, and compositionally mature. Calcareous sandstones from the Tordillos Deposit contain calcite as fibro-radial calcites amongst a wider, poikilotopic calcite matrix. Context of samples and methods described in; Chapter 6.

U-Pb geochronology data for Mindola Deposit, Zambia Copperbelt

U-Pb (Uranium – Lead) geochronology data of rutile from the Mindola Deposit Zambia Copperbelt. Full U/Pb isotope data, uncertainties and calculated ages for individual spot analyses for each sample and standard. Samples from Mindola North, Zambia, taken from the University of Southampton Archive. The samples were from the Kitwe Formation and included Dolomitic Siltstone, Quartz-Carbonate veins, Impure Dolostone and Anhydrite Conglomerate. The Kitwe Formation is the major host to Cu-Co mineralisation at Nkana-Mindola, particularly within the Ore Shale member. At Mindola and Mindola North, the Ore Shale is continuous along strike until a barren gap of siliceous dolostones called the Kitwe Barren gap. Overlying the Ore Shale are a series of quartzite, dolomitic argillites and dolostones of the Rokana Evaporites The remainder of the Kitwe Formation is overlain by the Upper Roan Group carbonates.

Integrated Hydrological Units of the United Kingdom View Service

This is a web map view service for the Integrated Hydrological Units (IHU) of the United Kingdom. The IHU define geographical reference units for hydrological purposes including river flow measurement and hydrometric data collection in the UK. The layers in this service represent the following component polygon layers: Hydrometric Areas with Coastline; Hydrometric Areas without Coastline; Groups; Sections; and Catchments. Each layer represents a different level of spatial detail. The coarsest level, Hydrometric Areas, is provided in two versions to meet differing user needs. Each Hydrometric Area is made up of one or more Groups. Each Group carries a name constructed from names of the major river flowing through the Group, the major river flowing into the Group, the major river into which the Group flows, and in some cases also from local county names. Each Group is made up of smaller units called Sections. A Section is the drainage area of a watercourse between two confluences. Only confluences of named watercourses were considered. Similarly to Groups, each Section carries a name constructed from names of the major river flowing through the Section, the major river flowing into the Section, and the major river into which the Section flows. Catchments represent the full area upstream from an outlet of every Section. Polygons within each layer do not have gaps and, with the exception of Catchments, polygons within one layer do not overlap. The Hydrometric Areas with Coastline layer covers Great Britain and Northern Ireland, but all other layers currently cover Great Britain only as no dataset with river geometries and names with suitable detail is available for Northern Ireland.

Postcode Unit Area - Great Britain

The Postcode Unit Area Feature Type is an area representation of the notional extents of areas containing addresses which share a common postcode unit. Notional extents are designed to enable users to display and analyse any data collected at the postcode unit level. These have been refined to avoid property extents and to follow the path of linear features such as roads, rivers and railways where possible. Polygons within this feature type are derived from georeferenced Royal Mail Postal Address File (PAF) delivery addresses. This feature type is for postcodes within Great Britain.

2023 - ongoing University of Plymouth (UoP) Isles of Scilly Trawling Impact BACI Survey

A new byelaw is expected to be passed which will close 43% of the Isles of Scilly district to bottom-towed fishing gear. The byelaw will allow permits to be distributed to up to six fishing vessels to use otter trawl and scallop dredge. The grounds around Scilly have not been trawled for over a decade, however there is now renewed interest to fish the water around Scilly. This creates a unique opportunity to conduct a Before-After-Control-Impact study on the impacts of bottom-towed fishing gear. At each site 3x45 minute BRUV video and 2X100m TUV transects were completed. This project will consist of a baseline against which changes to habitat complexity and biodiversity of associated communities can be quantified following resumption of trawling. This survey was also replicated at sites which will fall under the byelaw extension, which will act as reference sites.

The GEBCO_2025 Grid - the 2025 compilation of a continuous terrain model of the global oceans and land

The GEBCO_2025 Grid is a global continuous terrain model for ocean and land with a spatial resolution of 15 arc seconds. In regions outside of the Arctic Ocean and Southern Ocean areas, the grid uses as a base, Version 2.7 of the SRTM15+ data set between latitudes of 50 degrees South and 60 degrees North. This data set is a fusion of land topography with measured and estimated seafloor topography. Included on top of this base grid are gridded bathymetric data sets developed by the four Regional Centers of The Nippon Foundation-GEBCO Seabed 2030 Project. The GEBCO_2025 Grid represents all data within the 2025 compilation. The compilation of the GEBCO_2025 Grid was carried out at the Seabed 2030 Global Center, hosted at the National Oceanography Centre, UK, with the aim of producing a seamless global terrain model. Outside of Polar regions, the gridded bathymetric data sets supplied by the Regional Centers, as sparse grids, i.e. only grid cells that contain data were populated, were included on to the base grid with blending with the aim of generating a continuous terrain surface. The data sets supplied in the form of complete grids (primarily areas north of 60N and south of 50S) were included using feather blending techniques from GlobalMapper software. The primary GEBCO_2025 Grid contains land and ice surface elevation. In addition, a version of the data set is made available with under-ice topography/bathymetry information for Greenland and Antarctica. The GEBCO_2025 Grid has been developed through the Nippon Foundation-GEBCO Seabed 2030 Project. This is a collaborative project between the Nippon Foundation and the General Bathymetric Chart of the Oceans (GEBCO). It aims to bring together all available bathymetric data to produce the definitive map of the world ocean floor by 2030 and make it available to all. Funded by the Nippon Foundation, the four Seabed 2030 Regional Centers include the Southern Ocean - hosted at the Alfred Wegener Institute, Germany; Pacific Ocean - hosted at the National Institute of Water and Atmospheric Research, New Zealand; Atlantic and Indian Oceans - hosted at the Lamont Doherty Earth Observatory, Columbia University, USA; Arctic and North Pacific Oceans - hosted at Stockholm University, Sweden and the Center for Coastal and Ocean Mapping at the University of New Hampshire, USA.
