Introduction

Surface view of the Atlantic Ocean

The ocean (also the sea or the world ocean) is the body of salt water that covers approximately 70.8% of the surface of Earth and contains 97% of Earth's water. Another definition is "any of the large bodies of water into which the great ocean is divided". Separate names are used to identify five different areas of the ocean: Pacific (the largest) Atlantic, Indian, Southern (Antarctic), and Arctic (the smallest). Seawater covers approximately 361,000,000 km2 (139,000,000 sq mi) of the planet. The ocean is the principal component of Earth's hydrosphere, and therefore integral to life on Earth. Acting as a huge heat reservoir, the ocean influences climate and weather patterns, the carbon cycle, and the water cycle. (Full article...)

Waves in Pacifica, California

The sea, connected as the world ocean or simply the ocean, is the body of salty water that covers approximately 71 percent of the Earth's surface. The word sea is also used to denote second-order sections of the sea, such as the Mediterranean Sea, as well as certain large, entirely landlocked, saltwater lakes, such as the Caspian Sea.

Oceanography (from the Ancient Greek ὠκεανός "ocean" and γράφω "write"), also known as oceanology, is the scientific study of the ocean. It is an important Earth science, which covers a wide range of topics, including ecosystem dynamics; ocean currents, waves, and geophysical fluid dynamics; plate tectonics and the geology of the sea floor; and fluxes of various chemical substances and physical properties within the ocean and across its boundaries. These diverse topics reflect multiple disciplines that oceanographers utilize to glean further knowledge of the world ocean, including astronomy, biology, chemistry, climatology, geography, geology, hydrology, meteorology and physics. Paleoceanography studies the history of the oceans in the geologic past. An oceanographer is a person who studies many matters concerned with oceans including marine geology, physics, chemistry and biology. (Full article...)

The clipper route, followed by ships sailing between England and Australia or New Zealand

The clipper route was the traditional route derived from the Brouwer Route and sailed by clipper ships between Europe and the Far East, Australia and New Zealand. The route ran from west to east through the Southern Ocean, in order to make use of the strong westerly winds of the Roaring Forties. Many ships and sailors were lost in the heavy conditions along the route, particularly at Cape Horn, which the clippers had to round on their return to Europe.

The clipper route fell into commercial disuse with the introduction of marine steam engines, and the opening of the Suez and Panama Canals. However, it remains the fastest sailing route around the world, and as such has been the route for several prominent yacht races, such as the Velux 5 Oceans Race and the Vendée Globe.
