Introduction

The ocean (also the sea or the world ocean) is the body of salt water that covers approximately 70.8% of the Earth and contains 97% of Earth's water. An ocean can also refer to any of the large bodies of water into which the world ocean is conventionally divided. Separate names are used to identify five different areas of the ocean: Pacific (the largest), Atlantic, Indian, Southern, 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...)

A sea is a large body of salty water. There are particular seas and the sea. The sea commonly refers to the ocean, the wider body of seawater. Particular seas are either marginal seas, second-order sections of the oceanic sea (e.g. the Mediterranean Sea), or certain large, entirely landlocked, saltwater lakes (e.g. the Caspian Sea).

Oceanography (from Ancient Greek ὠκεανός (ōkeanós) 'ocean', and γραφή (graphḗ) 'writing'), also known as oceanology and ocean science, is the scientific study of the oceans. It is an 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 South China Sea, or South East Asian Sea, is a marginal sea of the Western Pacific Ocean. It is bounded in the north by the shores of South China (hence the name), in the west by the Indochinese Peninsula, in the east by the islands of Taiwan and northwestern Philippines (mainly Luzon, Mindoro and Palawan), and in the south by Borneo, eastern Sumatra and the Bangka Belitung Islands, encompassing an area of around 3,500,000 km² (1,400,000 sq mi). It communicates with the East China Sea via the Taiwan Strait, the Philippine Sea via the Luzon Strait, the Sulu Sea via the straits around Palawan (e.g. the Mindoro and Balabac Straits), the Strait of Malacca via the Singapore Strait, and the Java Sea via the Karimata and Bangka Straits. The Gulf of Thailand and the Gulf of Tonkin are also part of South China Sea. The shallow waters south of the Riau Islands are also known as the Natuna Sea.

South China Sea is a region of tremendous economic and geostrategic importance. One-third of the world's maritime shipping passes through it, carrying over US$3 trillion in trade each year. Huge oil and natural gas reserves are believed to lie beneath its seabed. It also contains lucrative fisheries, which are crucial for the food security of millions in Southeast Asia.

1 April 2023 –: Professor Alan Jamieson of the University of Western Australia's Minderoo-UWA Deep Sea Research Centre announces that his team has captured footage of a snailfish species, Pseudoliparis belyaevi, swimming at 8,336 metres (27,349 ft) in the Izu–Ogasawara Trench off Japan's southern coast. This is the lowest depth recorded for any fish, and closest to the estimated maximum depth possible for fish to survive. (BBC News)
