## Features[edit]

They was designed to carry out hydro-oceanographic surveys at high sea and in harbours and shallow waters, in order to guarantee the production and updating of nautical charts.
Main activities:
[3]

* sounding
* minimum depth
* topography of shorelines and port facilities
* seabed features
* collection of nautical and geographical data for the updating of nautical documentation
* detection of sunken vessels or dangerous underwater obstacles

The collected data are then processed by means of dedicated software programs and then used to produce:

* paper and electronic nautical charts for the safety of navigation
* Additional Military Layers
* nautical, scientific and technical documentation for mariners
* oceanographic databases for scientific purposes

## Characteristics[edit]

It is fitted with:

* multi-beam echo sounder Simrad EM300 (30 kHz)[4]
* single-beam echo sounder Simrad EA500 (12, 120 e 200 kHz)
* single-beam echo sounder Atlas Deso 25 (33, 100 e 210 kHz)
* Side Scan Sonar towed Simrad MS992
* differential and RTK satellite positioning systems
* Sippican XBT MK21 bathythermograph system
* CTD profiler with rosette system Ocean Seven 316 used for water sampling at different depths
* Van Veen buckets
* Sindel weather station

The ship is equipped one survey motor-boat for coastal and shallow water surveys fitted with:

* single beam Simrad EA400 (38 e 200 kHz)
* multi-beam echo sounders Simrad EM3000 (300 kHz)
