  • Seabed habitat map (current EUNIS classification system and submission) performed by CREOCEAN, LIENSs, EPOC, GEOTRANSFERT, RE NATURE ENVIRONNEMENT & IODDE within the framework of CARTHAM ("cartographie des habitats marins") project coordinated by the French Biodiversity Agency (Agence française pour la biodiversité, AFB). This map concerns polygons for which at least one habitat IS NOT in the current EUNIS classification (2007-2011). Digital data sources: orthos (2000), prefectural decrees Ground truth data sources (2011-2012): direct human observations Map confidence rated by Ifremer : 89%

  • Mapping of the Natura 2000 site FR5300017 "Abers - Côte des légendes" was jointly performed in the framework of three different actions: (i) the Natura 2000 convention for Brittany, and (iii) CARTHAM Project. It is based on the interpretation of various types of data from a number of surveys carried out between 2005-2012 both in the intertidal and subtidal zones. Additionally the seabed « Carte G » from the French hydrographic survey (SHOM) was used in the interpretation process. In the tidal zone the identification was made by interpreting coastal ortho-photographs from BD Ortho (2005 et 2009) and digitising them on scale 1 : 2000ème with further qualification of the polygons based on ground truth data. A confidence score in the [0-100] scale has been assigned to each polygon (SUM_CONF field) The compilation comprises the following various data sources. Lamarche S., Bajjouk T., 2013.

  • 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)
