Genealogia del dato – Processo di produzione

Geophysical data were collected by the Institute for Coastal Marine Environment (IAMC, now ISMAR, Institute of Marine Sciences) of the National Research Council (CNR) of Naples (Italy) during two oceano graphic surveys, ‘Linosa 2016’ (17–29 August 2016) and ‘BioGeoLin 2017’ (8–20 September 2017), onboard the R/V Minerva UNO (Di Martino et al., 2017; Innangi & Tonielli, 2017). Multibeam bathymetric surveys were carried out around Linosa Island from about 15 to 1000 m of depth, obtaining the almost whole coverage of its submarine flanks down to the base of the volcanic edifice and in surrounding areas. The shallow-water survey was performed from 15 to about 180 m of depth using a Teledyne Reson SeaBat 7125 while the seabed down to 1000 m of depth was investigated using a Teledyne Reson SeaBat 7160. Bathymetric data were collected and processed using Teledyne PDS 4.1; the software received positioning information from an Oministar Differential Global Positioning System (DGPS) and attitude data from an Ixea Octans 3000 motion sensor. Sound velocity values at multibeam transducers were provided by a Valeport mini-SVS probe, while a sound velocity profiler was systematically used to get the velocity profile in the water column. Both measurements are required for a proper depth computation. During the surveys various filter settings were applied to the multibeam data and quality control displays were used to check the data quality; data logging progress was shown in real-time using a color-coded Digital Terrain Model (DTM). The PDS Editing combines in a single module 3D swath editing, multibeam calibration, DTM editing and SVP editor and it allows to clean swath data and to update DTM model in real-time. Data de-spiking was carried out manually without the application of automatic filters in order to preserve data accuracy and resolution. Bathymetric data, previously collected in very shallow-water in the framework of a mapping project, were also available (Coastal Consulting Exploration s.r.l., 2008). This latter dataset was acquired in 2008 using Reson SeaBat 8125 and was integrated with the new data in order to expand the bathymetric map towards the coast (less than 15 m of the depth). These data were acquired only within the Pelagie Marine Protected Area (Innangi et al., 2018; Tonielli, Di Martino, & Innangi, 2017). Therefore, in the southern sector, which is not included in the MPA, the bathymetric data are missing in the range from 20 m to the coast.
