IEEE OES Members from the Engineering Faculty of Olavarría Participate in Underwater Acoustics Training

Two researchers from the Engineering Faculty of Olavarría (Universidad Nacional del Centro de la Provincia de Buenos Aires—UNCPBA) participated with colleagues, in training on equipment used for underwater acoustics. Part of the training was aboard an Argentine oceanographic vessel that participated in the search for the missing ARA San Juan. The submarine has been missing in the South Atlantic since November 15, 2017 and is still missing with all 44 crew members.

Sebastián Villar and Bruno Menna, IEEE OES members and researchers at the INTELYMEC Group (Technological Research in Electricity and Mechatronics), traveled to Buenos Aires and Mar del Plata to take part in the training. The intensive training course required joining the crew of the BIP (Buque de Investigación Pesquera—Fishing Research Vessel) Victor Angelescu for five days. The BIP Angelescu belongs to the INIDEP (Instituto Nacional de Investigación y Desarrollo Pesquero—National Institute for Fishery Research and Development). This oceanographic vessel is the most modern vessel that Argentina possesses and employs the most advanced technology for fishing and environmental research available. The state of the art sonars on the ship was a primary reason that is was chosen for the ARA San Juan mission. While anchored in the port of Buenos Aires, the BIP Angelescu received the oceanographers, marine biologists, physicists, engineers and personnel from the Argentinean Navy, who will employ the underwater acoustics instrumentation. Training was guided by Lars Anderssen (Head of Development of Acoustic Technologies) and Tonny Algroy (Manager), from the Norwegian company SIMRAD, who developed and manufactured the instrumention.

Both researchers were trained on the installation of the equipment, unique features, the broadband system (EK80), and the multibeam echo sounder (ME70). Equipment capabilities permit, among other things, permit the study of the water column, various acoustic research experiments and bio-acoustic analyses. Training during this course provides the necessary fundamentals for setting up the equipment and adapting it for employing it for varied research scenarios.

Mar Del Plata

Complementary training in Mar del Plata at the INIDEP facilities was also included. While there, the engineers focused on the processing of acoustic data, in a course presented by Rolf Korneliussen, a physicist with a doctorate specializing in underwater acoustics. Dr. Korneliussen leads the working group at Fisheries acoustics/Acoustics ecology, and is a global pioneer in acoustics research while at the Institute of Marine Research (IMR) of Bergen, Norway. With the data obtained in one of the missions on board the BIP Victor Angelescu, the scientists carried out processing and configuration exercises with state-of-the-art software. The experience gained during this training serves to strengthen and expand the work in underwater acoustics carried out by INTELYMEC at the laboratories of the Engineering Faculty, UNCPBA.
