Undersea barriers are structures or natural formations that impede or redirect the movement of marine organisms, sediments, or water flow in ocean environments. They can include artificial installations like underwater fences, artificial reefs, and barriers used in marine construction, as well as natural features like ridges or trenches. These barriers can impact marine ecosystems by influencing habitat connectivity, affecting species migration, and altering sediment transport processes. Their design and purpose often aim to protect certain areas, enhance marine habitats, or manage human activities such as fishing and shipping.
Undersea canyons can vary in depth, with some reaching depths of over 3,000 feet or more. The depth of an undersea canyon depends on various factors such as the geology of the area, tectonic activity, and ocean currents.

The islands of southern Europe, such as Sicily, Sardinia, and the Balearic Islands, are primarily formed by a combination of undersea mountains and volcanic activity. These landforms are geologically diverse, with some areas experiencing volcanic eruptions that have contributed to their formation over millions of years.
