Swath bathymetry of the Gulf of Porto Ercole, Tuscany, Italy

These bathymetric data were produced using the interferometric side-scan sonar onboard the Haliotis Research Vessel, Operated by Genavir, for the French Oceanographic Fleet, in October 2022, during the oceanographic campaign HISOPE (l'Haliotis pour l’Imagerie Sismique d’Orbetello et Pyrgi Etrusques).

The investigated area is located in front of the tombolo di Feniglia, in the Gulf of Porto Ercole. The goal of the campaign was to image the sedimentary architecture of the Tombolo di Feniglia

Acquisition took place from October 1st to October 6th 2022.

Data were acquired by eng. Quentin Layahe, Genavir, onboard the Haliotis, piloted by Serge Garcia, and post-processed using the software Globe, developed by the IFREMER, by Dr.Gilles Brocard (Archéorient, University of Lyon 2, France) and Alessandro Conforti, research engineer at the CNR (Italian national center for research) at Orosi, Sardinia.

Statement

Interferometric side-scan sonar of the Haliotis

A side-scan sonar builds detailed acoustic images of the seafloor.

The interferometric side-scan sonar comprises a bathymetric function. To make a side-scan sonar interferometric, the height of an echo on the bottom has to be linked to the angle of arrival by accurately measuring the phase difference of the arrival times on the various arrays stacked on either side. By using the true bearing and the slant range (obtained by other means), the position of the sounding points can be established in three dimensions.

The main advantage of an interferometric side-scan sonar over a multibeam sounder is its greater swath width in shallow water. Bathymetric measurements are, however, less accurate than those produced by a multibeam echo sounder and suffer from excessive noise at the end of the range.

The Haliotis is equipped with a Geoswath interferometric sonar fixed rigidly to the hull. The device functions at a frequency of 250 kHz.

Data were post-processed using  "Globe (GLobal Oceanographic Bathymetry Explorer) Software." (2019) developed by Cyrille Poncelet, Gael Billant, and Marie-Paule Corre
