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. Classification systems: EUNIS habitat classification system, with additional deep sea zones MSFD predominant habitats The Marine Habitat Classification for Britain and Ireland 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 The map follows the EUNIS 2007-11 classification system where it is appropriate.
Mapping of the Vatika Bay seafloor has been conducted in two different periods: in June 2010 and May 2015.The shallow, northern part of the Bay has been mapped in 2010 during the research project "PAVLOPETRI" by means of swath bathymetry (RESON SeaBat 7125 200/400 kHz), side scan sonar (Geoacoustics 100/400 kHz) and pinger (3.5 kHz) subbottom profiler. The deeper seafloor of the Bay has been surveyed in 2015 by means of side scan sonar and chirp subbottom profiling for the purposes of the research project "Environmental Study of Vatika Bay", funded by the Prefecture of Peloponnese. The research vessel "ALKYON" has been used in both cruises. The description of the nature of the seafloor and the habitat mapping has been based mostly on the interpretation of the acoustic-geophysical data and Sentinel-2 satellite imagery, as well as secondarily on the limited sampling performed in the area.
Delineation of the ICES Ecoregions was originally described in ICES Advice ACFM/ACE report(2004). In the present updated version, the delineation has been updated to account for additional policy objectives and reconciling of legislation (eg the MSFD and the EU water and habitats directives) The differences are based on the four principles: 1. Within the EU accept the MSFD regional and sub-regional definitions. 2. Separate Icelandic Seas from those around Greenland. 3. Use Large Marine Ecosystem units to define the Arctic Ocean. 4. Use the accepted Norwegian regional management plans definitions of the Norwegian and Barents Seas.
