[249] The sea is a recurring theme in the Haiku poems of the Japanese Edo period poet Matsuo Bashō (松尾 芭蕉) (1644–1694). [4](p7) Another 2.15% of Earth's water is frozen, found in the sea ice covering the Arctic Ocean, the ice cap covering Antarctica and its adjacent seas, and various glaciers and surface deposits around the world. By the beginning of the twentieth century, crossing the Atlantic took about five days and shipping companies competed to own the largest and fastest vessels. Marginal seas of the Arctic Ocean include: Barents Sea, Beaufort Sea, Chukchi Sea, Kara Sea and Laptev Sea. The battery-operated Mir submersibles have a three-man crew and can descend to 20,000 feet (6,000 m). [20] The subfield dealing with the sea's motion, its forces, and the forces acting upon it is known as physical oceanography. This means that the most productive areas, rich in plankton and therefore also in fish, are mainly coastal. By May 2013, 152 maritime nations had ratified MARPOL. [180] At least 145 species of seaweed – red, green, and brown algae – are eaten worldwide, and some have long been farmed in Japan and other Asian countries; there is great potential for additional algaculture. There’s no wind above waters. Here it is gradually warmed, becomes less dense, rises towards the surface and loops back on itself. [214], Desalination is the technique of removing salts from seawater to leave fresh water suitable for drinking or irrigation. Mediterranean seas of the Indian Ocean include: Persian Gulf and the Red Sea. Average sea level has risen between 10 cm and 25 cm in the past 100 years. There is less sea life on the floor of deeper seas but marine life also flourishes around seamounts that rise from the depths, where fish and other animals congregate to spawn and feed. They have viewing ports, 5,000-watt lights, video equipment and manipulator arms for collecting samples, placing probes or pushing the vehicle across the sea bed when the thrusters would stir up excessive sediment. The sea nettle is a group of jellyfish in the genus Chrysaora.The jellyfish gets its common name from its sting, which resembles that from a nettle or bee.
The sea, the world ocean, or simply the ocean is the connected body of salty water that covers over 70% of Earth's surface (361,132,000 square kilometres [139,434,000 sq mi]), with a total volume of roughly 1,332,000,000 cubic kilometres [320,000,000 cu mi]. Before the arrival of containerization in the 1950s, these goods were loaded, transported and unloaded piecemeal. The sea is important in human culture, with major appearances in literature at least since Homer's Odyssey, in marine art, in cinema, in theatre and in classic music, The sea is the interconnected system of all the Earth's oceanic waters, including the Atlantic, Pacific, Indian, Southern and Arctic Oceans. 44. It has been estimated that half of the world's oxygen is produced by phytoplankton. As they grate together, the continental plates are deformed and buckle causing mountain building and seismic activity. There is no sharp distinction between seas and oceans, though generally seas are smaller, and are often partly (as marginal seas) or wholly (as inland seas) bordered by land. [19] Furthermore, in 1921, the International Hydrographic Organization was set up, and it constitutes the authority on hydrographic surveying and nautical charting. [241][242] The Japanese artist Katsushika Hokusai created colour prints of the moods of the sea, including The Great Wave off Kanagawa. At the same time, sand and pebbles have an erosive effect as they are thrown against the rocks. It is surprising to note that the Black Sea’s total biodiversity makes up about one-third of that of the Mediterranean Sea. Something that was initially limited to a few individuals has now created biomass of one billion metric tons. [204], Seafloor massive sulphide deposits are potential sources of silver, gold, copper, lead and zinc and trace metals since their discovery in the 1960s. There is a continuous circulation of water in the oceans. Even though the range of the sea lion species extends from the cold subarctic to the warm tropical waters of the world’s oceans, there is one ocean where you won’t find any of them. The blue whale, Balaenoptera musculus, is the largest known animal ever to have lived on sea or land. google_ad_height = 600; Here it is subject to attrition as currents flowing parallel to the coast scour out channels and transport sand and pebbles away from their place of origin. The area of the Sargasso sea is approximately 8 times larger than the area of France. The Aral Sea in Kazakhstan and Uzbekistan, and Pyramid Lake in the western United States are further examples of large, inland saline water-bodies without drainage. [77], Oceans contain the greatest quantity of actively cycled carbon in the world and are second only to the lithosphere in the amount of carbon they store. The movement proceeds in jerks which cause earthquakes, heat is produced and magma is forced up creating underwater mountains, some of which may form chains of volcanic islands near to deep trenches.
[133] An atmospheric diving suit can be worn for deep sea operations, with a new world record being set in 2006 when a US Navy diver descended to 2,000 feet (610 m) in one of these articulated, pressurized suits. In more turbulent seas, frazil crystals join together into flat discs known as pancakes. Nonetheless, research published in Nature in April 2018 found that the aggressive effort of the Indonesian Minister of Maritime Affairs and Fisheries of Indonesia Susi Pudjiastuti to curtail illegal fishing has "reduced total fishing effort by at least 25%, (...) [potentially] generate a 14% increase in catch and a 12% increase in profit. [162], Nowadays, large quantities of goods are transported by sea, especially across the Atlantic and around the Pacific Rim. This cold water is often rich in nutrients and creates blooms of phytoplankton and a great increase in the productivity of the sea.

Mesh enclosures for finfish can be suspended in the open seas, cages can be used in more sheltered waters or ponds can be refreshed with water at each high tide. This began as the study of the shape of the ocean's currents[18] but has since expanded into a large and multidisciplinary field:[19] it examines the properties of seawater; studies waves, tides, and currents; charts coastlines and maps the seabeds; and studies marine life. Ballast water often contains species -- such as the zebra mussel and comb jellyfish -- that can colonize their new environment to the detriment of native species and local economies. Desalination is normally only undertaken where fresh water from other sources is in short supply or energy is plentiful, as in the excess heat generated by power stations. The two main processing methods, vacuum distillation and reverse osmosis, use large quantities of energy. The wave is pushed across the surface of the sea by the wind, but this represents a transfer of energy and not a horizontal movement of water. There is a noticeable change in temperature as well. Shrimps can be reared in shallow ponds connected to the open sea. [140], Control of the sea is important to the security of a maritime nation, and the naval blockade of a port can be used to cut off food and supplies in time of war. Climate change threatens to destroy the majority of the world’s coral reefs, as well as wreak havoc on the fragile economies of Small Island Developing States. Much of the destruction may be caused by the flood water draining back into the sea after the tsunami has struck, dragging debris and people with it. Some estimates put the amount available at between one and 5 million cubic kilometres (0.24 to 1.2 million cubic miles). [161] From the 16th to the 19th centuries, about 13 million people were shipped across the Atlantic to be sold as slaves in the Americas. [121] Around 500 BC, the Carthaginian navigator Hanno left a detailed periplus of an Atlantic journey that reached at least Senegal and possibly Mount Cameroon. The water moving away from the equator is warm, and that flowing in the reverse direction has lost most of its heat. Such events have created dead zones in the Baltic Sea and the Gulf of Mexico.
