Data identifying landscape areas (shown as polygons) attributed with type of mass movement e.g. landslip. The scale of the data is 1:10 000 scale. Onshore coverage is partial with approximately 30% of England, Scotland and Wales available in the version 2 data release. BGS intend to continue developing coverage at this scale; current focus is to include all large priority urban areas, along with road and rail transport corridors. Mass movement describes areas where deposits have moved down slope under gravity to form landslips. These landslips can affect bedrock, superficial or artificial ground. Mass movement deposits are described in the BGS Rock Classification Scheme Volume 4. However the data also includes foundered strata, where ground has collapsed due to subsidence (this is not described in the Rock Classification Scheme). Caution should be exercised with this data; historically BGS has not always recorded mass movement events and due to the dynamic nature of occurrence significant changes may have occurred since the data was released. The data are available in vector format (containing the geometry of each feature linked to a database record describing their attributes) as ESRI shapefiles and are available under BGS data licence.

This report is a contribution to the Strategic Environmental Assessment (SEA5) conducted by the Department of Trade and Industry (now Department of Energy and Climate Change). A review of the coastal distribution and abundance of swans and geese in the SEA 5 area, including migration routes, key feeding areas and roosting areas was carried out. A review of the potential impacts of offshore wind farms on swans and geese was also conducted. The study area was defined as the east coast of Scotland from the English border north to John O' Groats, including Orkney and Shetland, and the offshore waters in the SEA 5 area. The review considered nine species: mute swan, Bewick's swan, whooper swan, bean goose, pinkfooted goose, white-fronted goose, greylag goose, barnacle goose and brent goose. Offshore wind farms may impact birds directly by mortality from collisions or indirectly by displacement from migratory flyways or local flight paths. At present there are very little data on the effects of offshore wind farms on swans and geese. Of the nine species reviewed, five species, whooper swan, mute swan, pink-footed goose, greylag goose and barnacle goose occur in internationally important numbers at coastal sites in the SEA5 area. Greenland white-fronted goose occur in nationally important numbers.

High frequency (100 Hz) data from two horizontal induction coils measuring the Earth's magnetic field at the Eskdalemuir Observatory in the United Kingdom. The data covers the period from January 2015 to December 2015. Also included are examples of Matlab code and the frequency calibration files to convert to the raw data to SI units. Thumbnail spectrograms and metadata about the setup and equipment is also supplied.

The Lexicon of Named Rock Units provides definitions of lithostratigraphic, lithodemic, and litho-morpho-genetic geological units of the United Kingdom and its associated continental shelf. The Lexicon focuses mainly on units of Member, Formation, Group and higher rank (and equivalents) but it also includes information on some units of lesser rank, notably economically important coal seams and laterally extensive marine bands. It includes superficial and bedrock units. It includes synonyms and other names not currently recognised by the BGS or regarded as obsolete. Full Lexicon entries include geological unit name, a persistent unique identifier, map code, currency, rank, parent unit and rank, age, lithology, definitions of boundaries, thickness, previous and alternative names, geographical extent, type localities, and bibliographical references. This dataset is a snapshot of the live database taken on the 14th September 2017.

Quantitative Evaluation of Materials by Scanning Electron Microscopy (QEMSCAN®) analysis of thick sections of lava and tephra samples from the 2021 Tajogaite eruption from La Palma, Canary Islands. QEMSCAN® data were processed to produce a phase map and an olivine composition map per sample, in which each distinct phase/composition was assigned an 8-bit pixel intensity value. Olivine compositions were divided into 4 equal ranges of forsterite content (using the Fe-Mg ratio in the raw data) which were later calibrated using EPMA data. Pixels that did not fit the strict raw data requirements needed to be assigned a mineral phase were assigned to “Undifferentiated groundmass” , and instead reflect pixels containing glass or a combination of minerals ± glass below the pixel resolution. Isolated pixels of chemically complex phases such as amphibole may be the result of partial- or sub-volume interaction (i.e. between clinopyroxene, Ti-magnetite, plagioclase) and not a true representation of phase abundance. Isolated and small clusters of QEMSCAN® pixels of amphibole were shown by BSE data to be particularly prone to these effects, and so were added to the groundmass. Individual phase maps were extracted, labelled and analysed in Python using the pandas, numpy and skimage libraries. Pixel connectivity was determined by any of 4 neighbours, as opposed to 8 neighbours (any adjacent pixel including on the corners), which was more accurate in delineating groundmass crystals from each other. We chose an area of 10,000 microns2 to reflect the minimum size of phenocrysts, and assigned every region smaller than this limit to the groundmass. Phases that contributed =5% phenocrysts by area (normalised to solid rock area) in at least one sample were regarded as “major”, while the rest termed “minor”. Full details of the QEMSCAN® methodology is found in the accompanying Supplementary Data1_QEMSCAN spreadsheet.

Synthetic and real dispersion measurements for paths across the Pacific, consists of 2 datasets; SS3DPacific_new - This is a data set of surface-wave dispersion measurements. The dispersion is measured between a synthetic reference seismogram (computed with normal-mode summation using the MINEOS software in the radial model stw105 from Kustowski et al., 2008), and a real observed seismogram. This data set is used by Latallerie et al. (2024) to build a Vs model of the Pacific upper-mantle with full 3D resolution and uncertainty using SOLA inversion (Zaroli 2016) and finite-frequency theory (Zhou 2009). Data are for a set of source-receiver pairs for frequencies ranging from 6 to 21 mHz, every 1mHz. The measurement algorithm uses the multi-taper technique (Thompson 1982). The first 5 Slepians are used (Slepian 1978). A datum is the average of measurements over these tapers, and the uncertainty is the standard deviation.
