Habitat Map for Murlough Special Area of Conservation and Offshore, Northern Ireland
A biotope analysis of Dundrum bay was conducted in 2015 as part of efforts to understand the distribution and extent of benthic habitats and associated marine life within the Murlough special area of conservation incorporating new and historical groundtruthing information alongside modern acoustic data.
The map was originally presented in the Marine Habitat Classification for Britain & Ireland (http://jncc.defra.gov.uk/MarineHabitatClassification). This has been translated to the EUNIS habitat classification system for integration with other European datasets.

Lineage
Statement | The HABMAP project used a multi-parameter predictive modelling tool to develop seabed biotope maps for the Southern Irish Sea. Existing biological and physical datasets across the whole study area were collated within a Geographical Information System (GIS) and used to construct a rule-based biotope prediction model. Data were collated for the following physical parameters: bathymetry, sediment type, temperature, wave stress, tide stress, salinity and light attenuation. (NB Bedform data was not included in the extension project modelling work as it was found to be unreliable during the original project). These data were combined in GIS to produce a single map with many cells, each with a value for each of the physical parameters. Data was also collated for seabed biotopes and these points were overlain onto the physical data layer, allowing the relationships between each biotope and the physical environment to be determined. Preference ranges of each physical parameter were then identified for each biotope, leading to the development of predictive rules that could identify other cells with the same physical data ranges. This meant that maps could be produced showing the recorded and predicted distributions for each biotope. A final map was produced which listed all recorded and predicted biotopes in each cell, in order of confidence. The data used to create the model output is knows as Input data parameter maps. These have restricted access. The British Geological Society (BGS) derived seabed sediment map; Temperature data was provided by the Met Office; Bathymetry layer derived from Seazone hydrospatial dataset. Tidal and wave dataset were supplied by ABPmer (for DEFRA data layers project). There is a need to check the conditions of use before dissemination. |
