Introduction
Earth's ocean |

Main five oceans division: Further subdivision: Marginal seas |
The ocean is the body of salt water that covers approx. 70.8% of Earth. In English, the term ocean also refers to any of the large bodies of water into which the world ocean is conventionally divided. The following names describe five different areas of the ocean: Pacific, Atlantic, Indian, Antarctic/Southern, and Arctic. The ocean contains 97% of Earth's water and is the primary component of Earth's hydrosphere, thus the ocean is essential to life on Earth. The ocean influences climate and weather patterns, the carbon cycle, and the water cycle by acting as a huge heat reservoir. (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, nearly landlocked bodies of water. (Full article...)
Oceanography (from Ancient Greek ὠκεανός (ōkeanós) 'ocean', and γραφή (graphḗ) 'writing'), also known as oceanology, sea science, ocean science, and marine 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 seabed geology; 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, 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...)

Japanese whaling, in terms of active hunting of whales, is estimated by the Japan Whaling Association to have begun around the 12th century. However, Japanese whaling on an industrial scale began around the 1890s when Japan started to participate in the modern whaling industry, at that time an industry in which many countries participated.
During the 20th century, Japan was heavily involved in commercial whaling. This continued until the International Whaling Commission (IWC) moratorium on commercial whaling went into effect in 1986. Japan continued to hunt whales using the scientific research provision in the agreement and Japanese whaling was conducted by the Institute of Cetacean Research. This was allowed under IWC rules, although most IWC members opposed it. However, in March 2014, the UN's International Court of Justice ruled that the Japanese whaling program called "JARPA II," in the Southern Ocean including inside the Australian Whale Sanctuary, was not in accordance with the International Convention for the Regulation of Whaling, and was not for scientific purposes, as it had claimed. They ordered Japan to cease operations. In response to the ruling, Japan formulated a new Antarctic research whaling program, "NEWREP-A", to replace JARPAII. Under this program, 333 Antarctic minke whales were hunted each year from FY2015 to FY2018. Japan withdrew from the IWC and resumed commercial whaling on 1 July 2019, claiming that the IWC's original goal of sustainable whaling had been lost. As a result, Japanese whaling will now only take place in Japan's territorial waters and exclusive economic zones. (Full article...)Interesting facts -

- Photos of the rogue wave encountered by the MS Stolt Surf contributed to the growing evidence of their presence in the deep ocean.
- Frances has tied Arlene (at eight times) as the most-used name for tropical cyclones in the Atlantic Ocean.
