Bathymetry data (GeoTIFF grid format) of the Northern Adriatic Tegnùe di Chioggia site collected in 2014-2015 for the DeFishGear project
In the framework of the IPA Adriatic DeFishGear project (Derelict Fishing Gear Management System in the Adriatic region,, a two-year campaign for monitoring the typologies, abundance and distribution of marine litter in the Natura 2000 site "Tegnùe di Chioggia" ( was performed. The site is characterized by the presence of localized coralligenous buildups, widespread along the northwestern Adriatic Sea inner shelf between 10 and 40 m depths. These rocky buildups rise up to 3–4 m above the sandy-mud seafloor and have a patchy distribution. A variety of benthic calcareous constituents contribute to their growth, including bryozoans, molluscs, serpulid polychaetes, scleractinians and calcareous algae, the latter acting as the main bio-constructors. According to the European Habitats Directive (92/43/EEC), the marine rocky outcrop classification is included in the Annex I habitat types as "1170-Reefs" and "1180-Submarine structures made by leaking gases". The data on marine debris was collected with a Remotely Operating Vehicle (ROV) during two expeditions performed in May–June 2014 and July 2015 onboard the R/V Astrea of the Italian National Institute for Environmental Protection and Research (ISPRA) (Melli et al. 2017). The study area was mapped using a Kongsberg EM 2040 Multibeam (Kongsberg, Norway) to localize the rocky outcrops and to distinguish between soft and hard substrates. Here we present the maps of the main outcrops monitored in the site "Tegnùe di Chioggia" as well as other scattered outcrops in the area nearby. The processed data files were gridded at 0.5m resolution. The files are in GeoTIFF grid format.
Device Info
The data have been processed/modified to a level beyond that of basic quality control (e.g. final processed sonar data, photo-mosaics).
