  • An important task undertaken this year was to define sub-regional areas of the ICES greater North Sea eco-region. The sub-regional areas correspond to meaningful eco-logical units whose boundaries are defined by strong gradients in their physical oceanography, such as changes in depth, sediment transport, salinity, oxygen and currents. The four sub-regions of the ICES greater North Sea eco-region are; i. North-ern North Sea, ii. Southern North Sea, iii. Skagerrak and Kattegat, and iv. English Channel

  • The objective of this project was to generate seabed habitat maps for locations with full coverage acoustic datasets to as detailed a hierarchical level as possible within the Marine Habitat Classification for Britain and Ireland (version 04.05), also known as MNCR classification, (Connor et al. 2004). The acoustic data were at various stages of processing and interpretation, therefore the mapping of habitats and biotopes in some areas have required a greater amount of work to reach the same level compared to other areas. The constituent polygons within the habitat/biotope maps are labelled to an appropriate level of the Habitat Classification and translated to the corresponding EUNIS code. In order to generate seabed habitat maps for the areas the data associated with each area were required to undergo some preliminary preparation and processing in order to ensure suitability and compatibly with the mapping methodologies employed. The data were then processed using a top-down approach was adopted based on the methods developed by MESH and UKSeaMap and used by EUSeaMap, which utilised the updated seabed substrate information provided by BGS. Habitat maps for the area have been produced (the level of habitat detail which could be mapped was restricted to level 3 or 4 of the EUNIS classification and level 2 or 3 of the MNCR classification) with associated metadata and peripheral supplementary data to aid in future analysis and interpretation. A confidence assessment using the MESH confidence assessment method has been undertaken for each habitat map produced and certainty of classification maps accompany each habitat map also.
