  • 90th percentile Kinetic energy due to waves at the seabed in the Azores - Created by the MARETEC team at Instituto Superior Técnico (IST) (Technical University of Lisbon, Portugal) using WAVEWATCH III model. For the purpose of MeshAtlantic Project, values were integrated over 3 years. Values are averages of annual percentiles 90th. The spatial resolution of the dataset is 0.0027 decimal degrees (250m), but it has been resampled from an original dataset, the spatial resolution of which is 0.05 decimal degrees (4.5km)

  • A geostatistical analysis of the data is reported leading to the selection of a linear model of corregionalization for the composition of the sediment, based on the additive log-ratio transformation of data on mud, sand and gravel content. This model is then used for spatial prediction on a 250-m grid. At each grid node a prediction distribution is obtained, conditional on neighbouring data and the selected model. By sampling from this distribution, and backtransforming onto the original compositional simplex of the data, we obtain a conditional expectation for the proportions of sand, gravel and mud at each location, a 95% confidence interval for the value at each node, and the probability that each of the four sediment texture classes that underlie the EUNIS habitat classification is found at the node.

  • This dataset contains the habitats map from the SCI (Site of Community Importance) “Sistema de Cañones Submarinos Occidentales del Golfo de León”. The marine area “South-West Gulf of Lions canyons system” is located in the northeastern part of the Iberian Peninsula. The coastline belongs to the Catalan province of Girona, featuring a large number of rocky outcrops with many coves, small beaches, vertical cliffs and islets. Cape Creus is the most notorious element of the landscape, which corresponds to the easternmost part of the Pyrenees Mountains. This small peninsula is characterized by its wildness, and despite its low relief it penetrates into the Mediterranean Sea for more than 10 kilometers.This study was supported by the INDEMARES-LIFE+ Project, EC contract INDEMARES-LIFE+ (07/NAT/E/000732): Inventory and Designation of the Natura 2000 network in marine areas of the Spanish State (www.indemares.es/en). This work was coordinated by the Biodiversity Foundation (www.fundacion-biodiversidad.es). Habitats are classified according to EUNIS nomenclature and the List of Marine Habitats in Spain (LPRE, that it’s classified hierarchically and was completed and published in March 2013). Habitats classification are been simplified owing to the requirements of the EMODnet (European Marine Observation and Data Network) portal for Seabed Habitats.

  • Global habitat suitability of deep-water Antipatharia

  • This shapefile contains the digitised polygon boundaries of biotopes recorded within the rocky shore regions of the Teesmouth and Cleveland Coast SPA. The resource has been created under the requirements of the Natural England Marine Monitoring Framework. This work aimed to conduct phase 1 biotope surveys along already established transects; a rapid phase 1 biotope survey of the surrounding area; and collect survey data on the species composition of different biotopes, distribution and abundance of target prey species (birdfood) and determine the size distribution of 3 selected prey species. This shapefile represents the digitised field maps produced under the phase 1 biotope surveys.

  • A composite Habitats Directive Annex I feature extent map of Submarine structures made by leaking gases for the Scanner Pockmarks SAC was created by British Geological Survey for JNCC to provide the most up-to-date knowledge of Methane-Derived Authigenic Carbonate (MDAC) coverage within the site. Existing polygon data from the 2012 JNCC/CEFAS survey (CEND19x/12 ) was combined with information extracted from previous surveys. Backscatter data and side scan sonar data was used to characterise the nature of the seafloor, in particular the presence of methane-derived authigenic carbonate (MDAC), to build a composite understanding of “High” and “Potential” Annex I feature within the site.

  • Broadscale habitat (EUNIS level 3) for Runswick Bay recommended Marine Conservation Zone (rMCZ) BSH

  • This dataset contains the main habitats maps from the SCI (Site of Community Importance) “Banco de Galicia”. The Galician Bank is a deep underwater mountain located at the northwest of the Iberian Peninsula, 180 km from the Galician coast (in the north-east Atlantic Ocean). Its summit is located at a depth of between 650 and 1,500 metres. Its steep slopes descend from the summit to the abyssal plains located 4,000 meters below sea level. This study was supported by the INDEMARES-LIFE+ Project, EC contract INDEMARES-LIFE+ (07/NAT/E/000732): Inventory and Designation of the Natura 2000 network in marine areas of the Spanish State (www.indemares.es/en). This work was coordinated by the Spanish Institute of Oceanography (IEO, www.ieo.es) and the Biodiversity Foundation (www.fundacion-biodiversidad.es). The interpretation has been made possible thanks to direct and indirect samplings and geophysical data from campaigns "ECOMARG09", "INDEMARES_BANGAL0810", "INDEMARES_BANGAL0711" and "RADPROF0912". Habitats are classified according to EUNIS nomenclature and the List of Marine Habitats in Spain (LPRE, that it’s classified hierarchically and was completed and published in March 2013).

  • An updated Broadscale habitat (BSH)map was created based on a WGS84 datum. The new BSH map for the site was produced by analysing and interpreting acousticdata(both existing data aquired as part of the Civil Hydrography Programme (CHP)and data newly acquired during a targeted survey), and ground truth data collected by twodedicated surveysof this site(EA survey- SNGN 03/13 and Cefas survey - CEND01/13Y). Four main BSHs were identified, “A4.1Highenergy circalittoral rock”,“A4.2 Moderate energy circalittoral rock”, "A5.1 Subtidal coarse sediment"and “A5.2 Subtidal sand”.The circalittoral rock BSH are mapped as a complex, as it was not possible to delineate the energy regime based on available GIS data layers.

  • A composite Habitats Directive Annex I feature extent map of Submarine structures made by leaking gases for the Braemar Pockmarks SAC was created by British Geological Survey for JNCC to provide the most up-to-date knowledge of Methane-Derived Authigenic Carbonate (MDAC) coverage within the site. Existing polygon data from the 2012 JNCC/CEFAS survey (CEND19x/12 ) was combined groundtruthing information (PB and BGS datasets), to build a composite understanding of “High” and “Potential” Annex I feature within the site.
