The General Bathymetric Chart of the Oceans (GEBCO) is a publicly available bathymetric chart of the world's oceans. The project was conceived with the aim of preparing a global series of charts showing the general shape of the seafloor. Over the years it has become a reference map of the bathymetry of the world's oceans for scientists and others.

Areas beyond the 200 nautical miles limit of Exclusive Economic Zone (EEZs) of coastal states comprise 61% of the world's oceans. [13] Until the 1950s, areas beyond national jurisdiction were inaccessible for fishing activities, but advancements in the development of fishing technology (e.g., sonars, GPS, freezers) have enabled fishers to exploit the high seas.

More than 1100 species of fish [ 33 ] have been recorded in the Red Sea, and around 10% of these are found nowhere else. [ 34 ]
Between 1993 and 2018, the mean sea level has risen across most of the world ocean (blue colors). [71] Coastal ecosystems are facing further changes because of rising sea levels. Some ecosystems can move inland with the high-water mark, but others are prevented from migrating due to natural or artificial barriers.
