Since 2023 the IEEE OES MetroSea conference became a true international conference moving out of Italy and going to Malta. Since 2023 it was also sponsored by the IEEE Oceanic Engineering Society (OES). The new edition of IEEE MetroSea was held at Grand Hotel Bernardin – Portorož, Slovenia, on October 14-16, 2024. Portoroz belongs to the municipality of Piran.
Several important patronages helped for the best success of the IEEE MetroSea24 conference. Academic patronages come from the University of Ljubljana, the University of Sannio, the University of Napoli Parthenope, the University of Genoa, the University of Rijeka, the University of Montenegro, the University of Messina, the Technical University of Sofia, and the Gdynia Maritime University. Other patronages came from the IEEE OES Italy Chapter, the Italian Navy, the Italian National Council of Research (CNR), the OGS, and ISPRA.
Finally, it is worth to be underlined that for the first time MetroSea was included in the list of Ocean Decade Activities of the program “UN Decade of Ocean Science for Sustainable Development.”
The general Chairs were Jože Guna (IEEE Slovenia Section), Pasquale Daponte (University of Sannio), Salvatore Gaglione (University of Napoli Parthenope) and Franc Dimc (University of Ljubljana).

Slovenia is a small but diverse state located in southern Central Europe. It shares borders with Italy to the west, Austria to the north, Hungary to the northeast, and Croatia to the south and southeast. The name “Slovenia” means “land of the Slavs,” and the official language, Slovenian, is spoken by 2.5 million people worldwide. Part of the South Slavic language group, Slovenian, connects to a larger linguistic family of around 30 million speakers, primarily in the Balkans. As of 2024, Slovenia’s population stands at approximately 2.1 million. From 1918 to 1991, Slovenia was part of the Kingdom of Serbs, Croats, and Slovenes, and later Yugoslavia, where it became the most economically advanced republic. Today, Ljubljana is the capital, with other major cities including Maribor, Kranj, Celje, and Koper, which houses Slovenia’s only seaport.
Geographically Slovenia is for its largest part mountainous and forested accounting for about 20,271 km², roughly one seventh of New York state. Hence, the climate is temperate continental but for the Slovene littoral and the Alps. The Slovene littoral or littoral is the westernmost part of Slovenia bordering Italy and facing the Mediterranean Sea and is characterized by a Mediterranean climate. The southern part of it belongs to the Istrian peninsula. In this area we find the urban centers of Koper, Izola, and Piran.
Piran is a town known for its medieval architecture, with narrow streets and compact houses founded well before the Roman empire incorporation in 178 BC year. The first documented description of Piran is found in text by a cleric of Ravenna, Italy, in the 7th century AC. Its name is likely to come from the ancient Greek work “πυρρός” meaning flame-coloured, yellowish-red because in the area there were some red natural stones.

From 1283 to 1797, the town became part of the Republic of Venice, where it was governed in a semi-autonomous way, with a council of local noblemen assisting the Venetian delegate. Walking in Piran you can enjoy the Venetian style and its beauty.
The conference venue was not far away from the historical center of Piran, see Fig. 2. A walk of roughly 20 minutes took one from the conference venue to the old Venetian style town of Piran.
The main square (Figs. 3 and 4) of Piran is named after Giuseppe Tartini (1692–1770), composer and violinist of the Baroque era born in Piran in the Republic of Venice. Tartini was the first known owner of a violin made by Antonio Stradivari.
The accepted conference papers were 114, with a number of international registered attendees summing to 131. All articles submitted to IEEE MetroSea 2024, that have been accepted in a peer-reviewed process, have been published on IEEE Xplore Digital Library. Although this year no dedicated IEEE Journal of Oceanic Engineering (JOE) Special Issue was organized, all presenters are invited to submit their full journal papers to IEEE JOE if adhering to the journal scopes.
The Conference included 23 oral sessions and 2 poster sessions. Further, the conference schedule incorporates 3 keynote talks, 3 tutorials and 1 technical visit. The keynotes were held by Milena Horvat (Jožef Stefan Institute, Department of Environmental Sciences, Slovenia), Roberto Sabia (European Space Agency) and John R. Potter (Norwegian University of Science and Technology, Norway). All three keynotes were particularly appreciated and outstanding.
In Fig. 5 a picture of Milena Horvat lecturing is shown.

Figs. 6 and 7 show images taken during the keynote speech by Roberto Sabia entitled “ESA Ocean Remote Sensing Activities and Perspectives.”
In Fig. 8 it is shown John R. Potter having his keynote on “What next for ocean sensing and monitoring?”
In Fig. 9 the Distributed Acoustic Sensing concept for underwater monitoring is shown by John R. Potter. It is a distributed system able to “listen” whales, ships and earthquakes. It is based on optical fibers that are already present on the seabed.
The conference was vibrant, enjoyable and scientific valid with participation of people from Academias, Research Centers, Operational centers and Governmental bodies.
In Figs. 10-13 some oral and poster presentation moments are shown.
Many young people attended the conference. Authors and participants came from 20 countries including Slovenia, Italy, Croatia, Norway, Belgium, Netherlands, Albania, Romania, Spain, Portugal, Poland, Great Britain, Denmark, Greece, USA, Mexico, Democratic Republic of Congo, United Arab Emirates, Saudi Arabia and Hong Kong. Parallel oral sessions and poster sessions were organized out of the Plenary Sessions.

As usual, a set of emerging and well-established technical methodologies and applications were presented during the sessions, spanning a variety of topics that attracted the participants and promoted new networking chances.
Three Tutorials were included in the program, too, see Figs. 14-15. The training on marine drones was offered by CODEVINTEC.
The participants also visited the Piran Marine Biological Station, which looks after the Vida oceanographic buoy and regularly cooperates with the OGS in Trieste.
All social events were excellent and organized with great care and professionality. The gala dinner was held on 15 October at Restaurant Arkade – Hotel Histrion.
During the closing ceremony the awards were announced. The best paper award was given to the paper “Integrating topographic and underwater measurements for comprehensive coastal area inspection: an interdisciplinary approach” by Ali Alakbar Karaki, Ilaria Ferrando, Bianca Federici, Domenico Sguerso, Matteo Guideri, Roberto Nardini and Nunziante Langellotto of University of Genoa, Italy, and Ministry of Defence, Italy. In Fig. 16 the recipient Ali Alakbar Karaki is shown.

The second-best paper was achieved by Giulia Buttazzoni, University of Trieste, with coauthors Elena Marongiu, Fulvio Babich, Alessandro Fanti, Francesca Vatta and Massimiliano Comisso for their paper on “Phase-Only Antenna Array Synthesis with Beam/null Steering Capabilities for Propagation Impairment Mitigation in Coastal Environment.” The third best paper award was given to Jure Srše and Marko Perkovič, University of Ljubljana, Slovenia, for their paper on “Field Studies on Sediment Resuspension Induced by Shipping: Vessel Kinematic Measurements and Water Sampling in the Port of Koper.”
During the closing ceremony Fausto Ferreira, University of Zagreb, addressed the participants as representative of IEEE Oceanic Engineering Society, see Fig. 17.
IEEE MetroSea 2025 will be hosted in Genoa, Italy, (Fig. 18) 08-10 October, 2025. The IEEE Oceanic Engineering community is warmly invited to enjoy the Conference.

Professor Mal Heron is Adjunct Professor in the Marine Geophysical Laboratory at James Cook University in Townsville, Australia, and is CEO of Portmap Remote Ocean Sensing Pty Ltd. His PhD work in Auckland, New Zealand, was on radio-wave probing of the ionosphere, and that is reflected in his early ionospheric papers. He changed research fields to the scattering of HF radio waves from the ocean surface during the 1980s. Through the 1990s his research has broadened into oceanographic phenomena which can be studied by remote sensing, including HF radar and salinity mapping from airborne microwave radiometers . Throughout, there have been one-off papers where he has been involved in solving a problem in a cognate area like medical physics, and paleobiogeography. Occasionally, he has diverted into side-tracks like a burst of papers on the effect of bushfires on radio communications. His present project of the Australian Coastal Ocean Radar Network (ACORN) is about the development of new processing methods and applications of HF radar data to address oceanography problems. He is currently promoting the use of high resolution VHF ocean radars, based on the PortMap high resolution radar.
