Ziel der Reise / Objectives of Cruise:
' The main scope was to execute an interdisciplinary investigation to estimate abundance and distribution of pelagic organisms on the Sicily's southern platform, from Marsala to beyond Capo Passero for an area covering a total of approximately 2700 nm2. \n' In the second part of the campaign an acoustic survey around the Maltese Islands was carried out with the international cooperation of MEDSUDMED and coordinated by the FAO.\n\n=> more information

| CNRIAM | Mazzola Salvatore | 29 | trawls | B28 Acoustic reflection on marine organisms |
Acoustic surveys of stocks of small pelagic using the scientific multi-frequency echosounder Kongsberg Simrad EK500, with hull transducers and frequencies of 38, 120 and 200 kHz. The scientific echosounder was calibrated for the 3 frequencies using acousitic transmissions in the area of the sea that extends from Marsala to Siracusa. The calibration took place in the port of Siracusa, using the method of the sampling sphere of TS. During the echogram acquisition, the data was recorded on the har | no |
| CNRIAM | Mazzola Salvatore | 99 | transects | G06 Sampling by submersible |
Biological sampling of small pelagic organisms with pelagi ?monovolante? net equipped with Kongsberg Simrad ITI acoustic system for the control of geometry of the net during sampling. The net systems used were Flying type "Monobarca" of a total length of 78 meters and a width of 22 meters, vertical and horizontal openings of width respectively 7 meters and 13 meters for an area of the aperture of 90 meters squared approximately, the front net opening was 182x800 millimeters and lateral net op | no |
