Bathymetry of Ischia Island and its offshore (Italy), scale 1:50.000

Here, we show the bathymetric map of Ischia Island and its offshore area (Naples Bay, Italy), an active volcanic complex in the NW sector of Naples Bay. The map presented here is based on full seafloor coverage, carried out by merging multibeam swath bathymetric data acquired from several projects using different equipment, single beam echo-sounder data and topographic data, with a final grid cell size of 20 × 20 metres. The obtained Digital Terrain Model allows a full view of the main morphological units, and may help future geomorphologic and geologic interpretations of the study area. Several previously unknown morphologic highs of the seafloor are mapped and named, in honour of the main researchers and/or events which characterized the recent history of Ischia Island.
