Advancements in remote sensing technologies and marine robotics have revolutionized the surveying of underwater cultural heritage (UCH), surpassing the limitations of conventional means. In shallow water areas, Unmanned Surface Vessels (USVs) offer advantages over research vessels, such as extended autonomous operation, maneuverability, low power c...

Patras Gulf pockmark field (Western Greece) is a tectonically controlled field that has been activated at least twice by strong earthquakes (M5.4, 14 July 1993 and M6.4, 8 June 2008), and episodic gas seepages have been recorded in the past using geophysical means. A distributed temperature sensor (DTS) system was deployed inside a shallow pockmark...

Hellenic Petroleum S.A. has undertaken five Marine Seismic Surveys in the Greek territorial waters of the Ionian Sea between 2016 and 2023. Those were coupled with intensive marine noise monitoring programs, applied to 13 stations with a longitudinal span of about 300 km. Stations were mostly placed around Marine Protected Areas in coastal waters,...

Seagrasses are flowering plants, adapted to marine environments, that are highly diverse in the Mediterranean Sea and provide a variety of ecosystem services. It is commonly recognized that light availability sets the lower limit of seagrass bathymetric distribution, while the upper limit depends on the level of bottom disturbance by currents and w...

Our understanding of the distribution of coralligenous formations, throughout but mostly on the Eastern Mediterranean seafloor, is still poor and mostly relies on presence-only opportunistic trawling and fishermen reports. Previous efforts to gather this information created relevant geodatabases that led to a first draft predictive spatial distribu...

The marine environment is a dynamic and constantly changing place that supports an incredible diversity of life forms. In the ocean, corals and coralligene formations play an important role in providing habitats for a wide range of organisms. Habitat mapping is a method that has a significant growth recently and has become an essential tool in unde...
