Broad-scale habitat mapping

MESH Atlantic

The Atlantic area - MESH Atlantic project layer is a predictive map for the MESH Atlantic project area based on combining full-coverage physical data layers.

 

The aim of this work was to use ‘habitat envelopes’ to predict/model the distribution of broad-scale EUNIS marine habitat types. Through the development of the EUNIS marine habitat classification, key physical and environmental variables have been identified which are known to drive the distribution of biological communities, and thus EUNIS habitat types in our seas. Each habitat type within EUNIS is defined by its unique combination of environment variables (referred to as the habitat envelope) together with its associated biological community.

 

The technique of predicting EUNIS habitats was first developed by the MESH project in 2008; read more on the MESH website. Since then EUSeaMap extended the coverage, techniques and data quality (see below). Most recently, the MESH Atlantic project used similar methods to produce this layer. Note: for areas of overlap with EUSeaMap (mainly Ireland), the MESH Atlantic data is most recent. Download the broad-scale mapping report from the MESH Atlantic website.

Seabed images

MESH signatures catalogue

The MESH signatures catalogue map layer shows points through which the user can link to the online catalogue of seabed signatures developed by MESH and maintained by Ifremer for the MESH Atlantic project, by selecting a point with the Info (right-click) tool. A seabed signature is an image or suite of images with characteristics that are typical of a particular seabed feature. 

 

Marine landscapes

Belgium marine landscapes

The Belgium marine landscapes map layer is a predictive map based on combining physical data layers and follows the same methodology as the UKSeaMap project (see UK marine landscapes, below), but with different data layers. To create the Belgian marine landscape layer a classification tree was developed, based on the following categorised data sets: seabed substrata, seabed slope and bed-stress. Please note that the marine landscape types shown in this map have NOT been validated.

Netherlands marine landscapes

The Netherlands marine landscapes map layer is a predictive map based on combining physical data layers and follows the same methodology as the UKSeaMap project (see UK marine landscapes, below), but with different data layers. This study used four unclassified datasets from which six abiotic parameters were extracted: bathymetry, bathymetric position index, median grain size of the sand fraction (63 – 2000 μm), mud content, gravel content, and bottom shear stress.  These parameters were subsequently combined into three classified maps, and by combining these three classified maps the marine landscape map was the result.

Netherlands Wadden Sea marine landscapes

The Netherlands Wadden Sea marine landscapes map layer is a predictive map based on combining physical data layers and follows the same methodology as the UKSeaMap project (see UK marine landscapes, below), but with different data layers. The classification combines bathymetry and sediment and biotopes (e.g. saltmarshes) and is based on EUNIS level 4.

Northern France marine landscapes

The Northern France landscapes map layer is a predictive map based on combining physical data layers and follows the same methodology as the UKSeaMap project (see UK marine landscapes, below). To create the French marine landscape layer a classification tree was developed based on the following categorised data sets: seabed substrata, photic depth, wave base, bathymetry and tide-generated bed-stress. The resolution of the data varies with distance from the coast, with fine scale data close to the coast and coarse scale data in open water. Please note that the marine landscape types shown in this map have NOT been validated.

UK marine landscapes

The UK marine landscapes map layer is a predictive map based on combining physical data layers and was created as part of the UKSeaMap (2006) project. The aim of the UKSeaMap project was to use available geological, physical and hydrographical data, combined where possible with ecological information, to produce simple broadscale and ecologically relevant maps of the dominant seabed features for the whole sea under UK jurisdiction. To create the UK marine landscapes layer a classification tree was developed, based on the following categorised data sets: seabed substrata, photic depth, wave base, bathymetry, bottom temperature and tide-generated bed-stress. The data were biologically validated with seabed sample data and confidence assessment carried out.

Boundaries

MAIA project Marine Protected Areas

The MAIA project Marine Protected Areas layer shows the Marine Protected Area (MPA) boundaries collated by the Interreg IV B-funded project MAIA (Marine Protected Areas in the Atlantic Arc). The project focuses on the Atlantic waters of the four partner countries: France, Portugal, Spain and the UK. For more information about the MAIA project, go to the MAIA project website.

 

This layer is dynamically obtained via Web Map Services from the MAIA webGIS and is a good example of interoperability between web portals and linking between European-funded projects in the Atlantic area.

MESH project area (2004-2008)

The MESH project area (2004-2008) map layer simply shows the extent of the MESH Project area. This does not include the current MESH Atlantic Project area.

OSPAR North-East Atlantic Regions

The OSPAR North Atlantic Regions map layer shows the regional waters of the North-East Atlantic as described by the OSPAR commission. The waters covered by OSPAR are split into 5 regions with their own characteristics.

 

Further information may be found on the OSPAR website and the data can be downloaded through the OSPAR data download page
