Il dataset descrive la distribuzione degli habitat marini d'interesse comunitario (sensu Direttiva 92/43/CEE) all'interno delle Zone Speciali di Conservazione (ZSC) lungo le coste del Lazio La pubblicazione di riferimento è Ardizzone G., Belluscio A e Criscoli A., 2018. Atlante degli habitat dei fondali marini del Lazio. Sapienza Università Editrice.

L'atlante fornisce una base conoscitiva naturalistica dei fondali marino-costieri, dei loro principali popolamenti, fra i quali le praterie di Posidonia oceanica ed il Coralligeno. Il rilevamento dei dati cartografati tramite interpretazione di repertorio aerofotogrammetrico, di mappatura acustica con tecnica side scan sonar e di morfobatimetrica di dettaglio con tecnica multibeam, è integrato da materiale bibliografico scientifico di settore e dalle banche dati di Regione e Arpal. Il riferimento cartografico a terra è la CTR 1:10000. Il livello è un aggiornamento della mappatura allegata alla pubblicazione Atlante degli Habitat Marini della Liguria (Diviacco/Coppo-2006), così come approvato con D.G.R.n.141 del 28/02/2020.

First seabed map of the shallow-water areas of Lampione, the islet of the Pelagie Islands Marine Protected Area (Sicily Channel, Italy). The seafloor was mapped from the coast to a depth of about 75 m, using high-resolution multibeam systems (both for bathymetry and backscatter) along with ground-truth data in the form of grab samples and ROV videoobservations. By integrating these original data, a first seabed classification was produced through the use of the Remote Sensing Object Based Image Analysis, a semi-automatic segmentation approach. The resulting 1: 5.000 scale map includes sediment types and habitat distribution contributing to the knowledge of the peculiar marine ecosystem observed at Lampione. In particular, the map provides the first indication of the wide occurrence of rhodolith/maërl habitats at Lampione, which are among the most important ecosystems in the Mediterranean Sea.

Seabed mapping in the Pelagie Islands marine protected area (Sicily Channel, southern Mediterranean) using Remote Sensing Object Based Image Analysis (RSOBIA)

A seabed map around Lampedusa, the largest island of the Pelagie Islands Marine Protected Area (Italy, western Mediterranean). The seafloor was mapped using bathymetry and backscatter multibeam systems along with an underwater camera for direct observations and ground truthing, from the coastal area to about 50 m depth. The map was produced to monitor the present-day distribution of the Posidonia oceanica meadows around the Island. P. oceanica is the most important endemic seagrass species of the Mediterranean Sea and it can form meadows or beds extending from the surface to 40–45 m depth. These meadows provide habitat for a large community, thus increasing biodiversity of the coastal zone, stabilizing sediments and reducing coastline erosion. The seagrass meadows are susceptible to regression as response to specific impact, thus their presence and abundance can be considered an indicator of the overall environmental quality of the coastal zone. The European Union’s Habitat Directive (92/43/CEE) includes P. oceanica beds among priority habitats and, according to the Water Framework Directive (2000/60/EC), each EU Member State defined the method to evaluate the health status of the seagrass; more recently, within the Marine Strategy Framework Directive (MFSD) (2008/56/EC), P. oceanica has been selected as an indicator of the Good Environmental Status for marine areas. Consequently, the Pelagie Islands Marine Protected Area launched a project to assess the conservation status and map the distribution of P. oceanica meadows. The resulting 1:15,000 scale map includes information about the Mediterranean seagrass and the distribution of five acoustic facies reflecting hard lithologies and soft substrates. The Lampedusa seabed map provides new information which contributes to the development of a detailed benthic habitat map and a more comprehensive maritime spatial planning of this Marine Protected Area.

The shapefile contains the marine substrates of the Campania Region (inside 24 NM) produced in the framework of the FEAMP-ISSPA Project by CNR-ISMAR starting from the CARG cartography and the EUSeaMap from EMONnet.

Benthic habitat map of the Campania Region produced in the framework of the FEAMP-ISSPA Project by CNR-ISMAR

The shapefile contains the priority habitats of the Campania Region (inside 24 NM) produced in the framework of the FEAMP-ISSPA Project by CNR-ISMAR. It is the results of a bibliographic review coupled with new data (FEAMP-ISSPA) and recovered geophysics data collected by CNR-ISMAR through the years. The shapefile includes coralligenous, maerl, Posidonia oceanica, Cymodocea nodosa, photophilic algae, bioconstructions, and cold-water corals.
