Collation of habitat polygon records contributing to the Geodatabase of Marine features adjacent to Scotland (GeMS). Records are attributed as to their qualification as protected features of protected areas within the Scottish MPA network. Where appropriate typical record details will include: status as Scottish Priority Marine Features or Annex I Habitat, MNCR biotope, EUNIS habitat, date, date range, year, status, accuracy, determiner and details of where the records are sourced from and intellectual property ownership. Polygon area values in the HECTARES field are calculated using ETRS89-LAEA (EPSG:3035) using the standard centre of projection at 10° E, 52° N.

Layers relate to: the components of Priority Marine Features (PMF), MPA Search features (Black guillemot or Large-scale features of functional significance used to underpin the selection of Nature Conservation Marine Protected Areas (NC MPA)). Our knowledge about the marine environment, and about which locations should be recommended as MPAs, comes from a range of sources: from targeted surveys led by SNH, JNCC and Marine Scotland focussed on marine habitats and species relevant to Priority marine Features (PMF), survey work conducted by industry, volunteers recording information while enjoying the marine environment for recreation. Information varies from recent to much older. There are a number of different types of data which have been collected using a range of different methods. Data has been placed into a standardised structure to support its use. Depending on who collected them, and for which purpose, some data were in a format we could use immediately while other data needed to be processed before they were able to be used in the Scottish MPA project. The information has been collated in a computer database called GeMS (Geodatabase for Marine Habitats and Species adjacent to Scotland) and has underpinned much of the Scottish Marine Protected Areas process. These layers update and build upon mapping presented in Baxter et al., 2011. Scotland's Marine Atlas: Information for the national marine plan. Marine Scotland, Edinburgh. pp.191

Confidence in the PAR at seabed values, produced by EMODnet Seabed Habitats for the 2016 EUSeaMap broad-scale predictive habitat maps. Values are on a range from 1 (Low confidence) to 3 (High confidence). Confidence in Photosynthetically Active Radiation (PAR) at the seabed are driven by the confidence in the underlying data used to determine the descriptor (PAR at the surface, light attenuation coefficient KD(PAR) and depth to the seabed.) and the confidence in the threshold/margin between classes (areas closer to a boundary between two classes will have lower confidence).

Confidence in the depth to seabed, produced by EMODnet Seabed Habitats for the 2016 EUSeaMap broad-scale predictive habitat maps. Values are on a range from 1 (Low confidence) to 3 (High confidence). The EMODnet Bathymetry project was the source of the depth to the seabed dataset (a digital elevation model (DEM). The project also produced a ‘quality indicator’ based on data relative age, relative sampling effort and number of soundings. The quality indicator scores were categorised into "high", "moderate" and "low" confidence. Detailed information on the confidence assessment is in Populus J. et al 2017. EUSeaMap, a European broad-scale seabed habitat map. Ifremer. http://doi.org/10.13155/49975

Confidence in kinetic energy due to current values, produced by EMODnet Seabed Habitats for the 2016 EUSeaMap broad-scale predictive habitat maps. Values are on a range from 1 (Low confidence) to 3 (High confidence). The confidence assessment considered factors such as: • Quality of training data and methods used to construct the model. • Temporal resolution. • Spatial resolution Detailed information on the confidence assessment in Populus J. et al 2017.

Confidence in the 2016 EUSeaMap salinity regime class in the Baltic Sea and Kattegat strait in the North Sea/Baltic Sea, produced by EMODnet Seabed Habitats for the 2016 EUSeaMap broad-scale predictive habitat maps. Values are on a range from 1 (Low confidence) to 3 (High confidence). Confidence in salinity regime are driven by the confidence in the salinity data used to determine the descriptor, and the confidence in the threshold/margin between classes (areas closer to a boundary between two classes will have lower confidence).

Output of the 2016 EUSeaMap broad-scale predictive model, produced by EMODnet Seabed Habitats. The extent of the mapped area includes the Mediterranean Sea, Black Sea, Baltic Sea, and areas of the North Eastern Atlantic extending from the Canary Islands in the south to Norway in the North. The map was produced using a "top-down" modelling approach using classified habitat descriptors to determine a final output habitat. Habitat descriptors differ per region but include: Biological zone Energy class Oxygen regime Salinity regime Seabed Substrate Riverine input Habitat descriptors (excepting Substrate) are calculated using underlying physical data and thresholds derived from statistical analyses or expert judgement on known conditions. The model is produced in Arc Model Builder (10.1). The model was created using raster input layers with a cell size of 0.002dd (roughly 250 meters). The model includes the sublittoral zone only; due to the high variability of the littoral zone, a lack of detailed substrate data and the resolution of the model, it is difficult to predict littoral habitats at this scale. The map follows the EUNIS 2007-11 classification system where it is appropriate. For details on methodology see: Populus J. And Vasquez M. (Eds), 2017.

The dataset shows larger expanses of bare peat across Scotland from Sentinel 2 imagery taken in summer 2018. Resolution of 10m x 10m Sentinel 2 pixels. Produced by GIG Earth Observation team for the Peatland Action project to be used at a regional scale to identify those parts of Scotland with the most exposed peat.
