A Strait is a naturally formed, narrow, typically navigable waterway that connects two larger bodies of water. It most commonly refers to a channel of water that lies between two land masses. It is used for international navigation through the territorial sea between one part of the high seas or an exclusive economic zone and another part of the high seas or an exclusive economic zone are subject to the legal regime of transit passage.

For countries with multiple and separate coastlines, EEZs were grouped based on country, latitude, habitation, and ocean basin. Figure 1. Nineteen 19 of the areas contain marine waters and all but one of them, Number 37, the Mediterranean Sea, contain High Seas areas. The Ocean Health Index analyzes areas 58, 88 and 48 with its Antarctic area and the other 15 areas as its High Seas area.
We celebrate World Oceans Day to remind everyone of the major role the oceans have in everyday life. They are the lungs of our planet, providing most of the oxygen we breathe. They are a major source of food and medicines and a critical part of the biosphere.

The oceans of the Earth are all connected. They are truly one "world ocean" which covers about 71 percent of the Earth's surface. The salt water which flows from one part of the ocean to another without hindrance makes up 97 percent of the planet's water supply. Geographers, for many years, divided the world ocean into four parts: the Atlantic, Pacific, Indian, and Arctic Oceans. In addition to these oceans, they also described many other smaller bodies of salt water including seas, bays, and estuaries. It wasn't until that a fifth ocean was officially named: the Southern Ocean, which includes the waters around Antarctica.
For many years only four oceans were officially recognized, and then in the spring of , the International Hydrographic Organization established the Southern Ocean by determining its limits. Those limits include all water below 60 degrees south, and some of it, like the Arctic Ocean, is frozen. The world ocean is the principal component of Earth's hydrosphere, it is integral to all known life, forms part of the carbon cycle, and influences climate and weather patterns. The world ocean is the habitat of , known species, but because much of it is unexplored, the number of species that exist is much larger, possibly over two million. The origin of Earth's oceans remains unknown; oceans are thought to have formed in the Hadean period and may have been the impetus for the emergence of life. Though generally described as several separate oceans, these waters comprise one global, interconnected body of salt water sometimes referred to as the World Ocean or global ocean.
