Created by JNCC, UKSeaMap 2018 gives a broad-scale overview of the coverage of different physical seabed habitats in the UK. It is classified according to three schemes:
- Marine Habitat Classification for Britain and Ireland v15.03
- EUNIS marine habitat classification system, with additional deep-sea zones
- MSFD benthic broad habitat types
Data product summary
UKSeaMap 2018 is a composite of two broad-scale habitat maps, arranged in the following priority order to produce a single layer:
- A roughly 100 m* resolution broad-scale habitat map, which covers the majority of the UK shelf area
- EUSeaMap 2016, a coarser resolution** broad-scale habitat map, which covers all European seas
Both of these datasets have been created using identical methods; the only differences are in the resolution of the seabed substrate input data and the source and resolution of the depth data. UKSeaMap 2018 is therefore able to use the more detailed data available for UK waters to create a product based on the best-available evidence.
* 3 arc second = 93 m (latitudinally) by 44-53 m (longitudinally)
** 7.5 arc second = 232 m (latitudinally) by 109-155 m (longitudinally)
Relationship to other projects
Since 2016, UKSeaMap has been a value-added product based on EUSeaMap, an output of the EU-funded EMODnet Seabed Habitats initiative, which JNCC has taken a leading role in since its inception in 2009.
A new version of EUSeaMap was published in 2019; we are now working on an update to UKSeaMap to account for this.
