Metadata: UKSeaMap Predictive Map 2025.1
Abstract:
The UKSeaMap Predictive Habitats Map 2025 (version 1) is a broad-scale prediction that uses physical models of depth, light, sediment and energy to predict the physical seabed habitats for the whole UK seabed. This map covers the UK extended Continental Shelf as defined by the Continental Shelf (Designation of Areas) Order 2013, but excluding the intertidal zone, Dee Estuary and Morecambe Bay. Two classification systems are present in the final output: * EUNIS habitat classification system version 2007-11 * The Marine Habitat Classification for Britain and Ireland (https://mhc.jncc.gov.uk/) version 22.04 The attribute table includes a column for each of level 2, level 3 and level 4 of each of these two classification schemes. In some cases, there were 2-3 options of habitat type, which were both included and separated by the word “OR“. There is also a column containing the most detailed unique habitat type for each of the two classification systems. The habitats were determined by combining 4 categorical input layers called 'habitat descriptors', which are the basis for describing physical habitats in the Marine Habitat Classification for Britain and Ireland. These are also present in the geodatabase. Habitat descriptor data layers: Seabed substrate type - created using the British Geological Survey's national broad-scale predictive sediment map - Marchant et al. (2025) and the JNCC-BGS-Cefas national broad-scale predictive rock map (JNCC, 2019) Biological zone (also known as biozone) - created using the depth to seabed, wave disturbance at the seabed and amount of light reaching the seabed. Kinetic energy at the seabed - created using energy from tidal currents and energy from waves Salinity regime - created using the Annex I Habitats Regulations datasets for coastal lagoons and estuaries features A methods report will be published in due course.

| Internal code | Internally assigned metadata identifier | 11418 |
| Title | The title is used to provide a brief and precise description of the dataset such as 'Date', 'Originating organisation/programme', 'Location' and 'Type of survey'. All acronyms and abbreviations should be reproduced in full. | UKSeaMap Predictive Map 2025.1 |
| File Identifier | The File Identifier is a code, preferably a GUID, that is globally unique and remains with the same metadata record even if the record is edited or transferred between portals or tools. | 78c35b12-111d-47e2-a3ec-88e8a9f5cb22 |
| Resource Identifier | This is the code assigned by the data owner. | UKSM2025_1 |
| Resource type | The resource type will likely be a dataset but could also be a series (collection of datasets with a common specification) or a service. | dataset |
| Start date | This describes the date the resource starts. This may only be the year if month and day are not known | 2025-04-10 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2025-04-10 |
| Spatial resolution | This describes the spatial resolution of the dataset or the spatial limitations of the service. | inapplicable |
| Frequency of updates | This describes the frequency with which the resource is modified or updated i.e. a monitoring programme that samples once per year has a frequency that is described as 'annually'. | asNeeded |

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | 11/04/2025 - UKSeaMap Predictive Map 2025.1. This version replaces the UKSeaMap 2018 Version 2. This is a complete remake of UKSeaMap, which uses a new seabed substrate layer produced by the British Geological Survey. This work was funded by the Department for Environment, Food and Rural Affairs (Defra) as part of the marine arm of the Natural Capital and Ecosystem Assessment (NCEA) programme: NC42: mNCEA for GES. 2018/12/17 – UKSeaMap 2018 Version 2 replaces UKSeaMap2018 released in October 2018 and UKSeaMap2016 – The following updates were made: 1) Correction of the correlation table: in previous versions the deep sea “sandy mud to muddy sand” has been equated to EUNIS muddy sand and called "A6.4 deep sea muddy sand", instead of "A6.5 deep sea mud" (see also ChangeDec18 attribute); 2) Translation into JNCCv15 Habitats; 3) Reclassification of substrate in "A6.4 or A6.5 polygons" (FOLK Muddy sands) based on UKSeaMap 2010 and BGS PSA data; 4) Addition of EUNIS Level 3 habitats attribute (EL3_LON18) ~~~~~ Updated 2018/10/12: UKSeaMap 2018 replaces UKSeaMap2016. Substrate updated in most of UKShelf as a result of the publication of "Prediction of outcrops or subcrops of rock in UK shelf seabed" doi:10.25603/840424.1.0.0 ~~~~~ Updated 2017/10/16: MSFD predominant habitats reclassified as MSFD Benthic Broad Habitat Types (as defined in Commission Decision May 2017). Composite data product, created by merging the UK 3-arc-second case study and EUSeaMap 2016 outputs of EMODnet Seabed Habitats phase 2. The UK 3-arc-second dataset was erased (in ArcGIS) from EUSeaMap 2016, to create a single full-coverage and flat dataset, before clipping to the UK continental shelf. |
