Ant├│nio PT001007 2011-05-20T00:00:00 Map based on available information of marine charts and two surveys. Preliminary map preparation involved scanning, georeferencing and digitizing of pre-existing base map from the Portuguese Hydrographic Institute and harmonization with other published and non-published cartographic information. Samples of soft bottom shelf sediments from nearly 100 sites, collected in the scope of the ACOSHELF project, were analyzed for grain-size, total organic matter and macrofaunal comunities.

Ant├│nio 2011-05-20 ┬À a literature review of the existing information on the sedimentary distribution on the Portuguese continental shelf; ┬À scanning of pre-existing and published maps by the Portuguese Hydrographic Institute ÔÇô Instituto Hidrogr├ífico (IH), 1:150.000 scale, with the distribution of the surficial sediments on the Portuguese continental shelf; ┬À georreferencing the obtained raster images to the world WGS-84 geographic coordinate system; ┬À vectorization of the Portuguese mainland coastline and the bathymetric curves of 20m and 50m; ┬À projection of the sedimentological data (grain size) obtained in the oceanographiccampaigns associated with the project and subsequent classification within the system FOLK MESH-ATLANTIC, using the tool GRAPHERTM 7 (Golden Software, Inc.); ┬À representation and analysis of the sediment samples from the Portuguese continental shelf in the map produced in ArcGIS; ┬À harmonization of sedimentological data available in the literature reviewed, particularly in the maps published by IH, with the classification system adopted in FOLK MESH-ATLANTIC project. This phase required in some cases, georreferencing new maps of interest; ┬À vectorization and mapping the sedimentological maps published in the IHÔÇÖs ÔÇ£S├®rie PescaÔÇØ and "Carta dos Sedimentos Superficiais da Plataforma Continental Portuguesa"; ┬À construction of a synthetic base map of the sediment distribution on the Portuguese continental shelf. For this purpose it was necessary to consider the previous scientific papers published on the sedimentological data of interest to the project; ┬À cataloguing of vector data (metadata) in "GeoNetwork OpensourceÔÇØ platform using a template according to the ISO19139 standard; ┬À the biological data were analyzed in the SIMPER routine of the PRIMER v6 and using the Constancy and Fidelity indexes; ┬À the sedimentary and biological classes were converted to the EUNIS level 5 classes. false
