UKSeaMap 2016 - a broad-scale seabed habitat map for the UK

 

Overview

UKSeaMap 2016 is a broad-scale habitat map for UK waters. UKSeaMap version 2016 has been archived. The latest version of UKSeaMap (2018) is available from the UKSeaMap 2018 page.

In UKSeaMap 2018 the substrate input data layer has been updated with new evidence on presence of outcropping rock at the seabed.

 

UKSeaMap 2016 has been generated by JNCC and is a by-product of the 2013-2016 activities of the EMODnet Seabed Habitats 2013-2016 consortium. It is a composite of two broad-scale habitat maps, arranged in the following priority order:

1.      A roughly 100 m* resolution broad-scale habitat map, which covers the majority of the UK shelf area

2.      EUSeaMap 2016, a coarser resolution** broad-scale habitat map, which covers all European seas (view/download on the EMODnet Seabed Habitats interactive map).

Both of these datasets have been created using identical methods; the only difference is in the resolution of the seabed substrate input data and the source and resolution of the depth data.

* 3 arc second = 93 m latitudinally by between 44 m (north) and 53 m (south) longitudinally

** 7.5 arc second = 232 m latitudinally by between 109 m (north) and 155 m (south) longitudinally

 

UKSeaMap2016

Classification system:

 

Input data layers:

  • Seabed substrate type
  • Depth to the seabed
  • Amount of light reaching the seabed
  • Wave disturbance at the seabed
  • Kinetic energy at the seabed caused by tidal currents and waves
 

Outputs:

  • Predictive seabed habitat map  
  • Confidence layers
 

Methods

 
A brief note on the justification for, and method used to construct UKSeaMap 2018 from the EMODnet Seabed Habitats outputs with be uploaded here in early 2019.
 
A full, detailed description of the method used to create the EMODnet Seabed Habitats broad-scale habitat maps can be found in the EUSeaMap technical report on the EMODnet Seabed Habitats website.

Relationship to past projects

UKSeaMap 2018 superseded previous UK-wide broad-scale seabed habitat maps, including UKSeaMap 2016, EUSeaMap 2012, UKSeaMap 2010, MESH 2008 and UKSeaMap 2006. It has built on the work of these projects and uses the most recent available data and methods.
