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 oceans. 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...)

Satellite image of the South China Sea

The South China 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 Strait), the Strait of Malacca via the Strait of Singapore, and the Java Sea via the Karimata and Bangka Strait. The Gulf of Thailand and the Gulf of Tonkin are also part of the South China Sea. The shallow waters south of the Riau Islands are also known as the Natuna Sea.

The 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.

USNS Southern Cross cargo operations at ice pier. McMurdo Station, Antarctica; 1983. The en:ice pier had been in use four seasons. Workers made the ice pier by repeatedly flooding an area with water which quickly turned to ice. However, by the time of 1983 cargo operations, the pier was rapidly deteriorating. Severe cracks appeared in the surface even as tidewaters further undercut the pier's edge causing large chunks of ice to break off.

Cyclone Catarina from the ISS on March 26 2004.JPG
Before the year 2004, only two tropical cyclones had ever been noted in the South Atlantic Basin, and no hurricane. However, a circulation center well off the coast of southern Brazil developed tropical cyclone characteristics and continued to intensify as it moved westward. The system developed an eye and apparently reached hurricane strength on Friday, March 26, before eventually making landfall late on Saturday, March 27, 2004.
The crew of the International Space Station was notified of the cyclone and acquired excellent photographs of the storm just as it made landfall on the southern Brazilian state of Santa Catarina (the storm has been unofficially dubbed “Cyclone Catarina”). Note the clockwise circulation of Southern Hemisphere cyclones, the well-defined banding features, and the eyewall of at least a Category 1 system. The coastline is visible under the clouds in the upper left corner of the image.

Polar bears near north pole.jpg
Three Polar bears approach the starboard bow of the Los Angeles-class fast attack submarine USS Honolulu (SSN 718) while surfaced 280 miles from the North Pole. Sighted by a lookout from the bridge (sail) of the submarine, the bears investigated the boat for almost 2 hours before leaving. Commanded by Cmdr. Charles Harris, USS Honolulu while conducting otherwise classified operations in the Arctic, collected scientific data and water samples for U.S. and Canadian Universities as part of an agreement with the Arctic Submarine Laboratory (ASL) and the National Science Foundation (NSF). USS Honolulu was the 24th Los Angeles-class submarine, and the first original design in her class to visit the North Pole region. Honolulu was assigned to Commander Submarine Pacific, Submarine Squadron Three, Pearl Harbor, Hawaii.

An adult and sub-adult Minke whale are dragged aboard the Nisshin Maru, a Japanese whaling vessel that is the world's only factory whaling ship. The wound that is visible on the calf's side was reportedly caused by an explosive-packed harpoon.
This image was taken by Australian customs agents in 2008, under a surveillance effort to collect evidence of indiscriminate harvesting, which is contrary to Japan's claim that they are collecting the whales for the purpose of scientific research. In 2010, Australia filed a lawsuit in the International Court of Justice hoping to halt Japanese whaling; this photograph will undoubtedly play a key role in that pending case.

1710 De La Feuille Map of Africa - Geographicus - Africa-lafeuille-1710.jpg
A very scarce, c. 1710, map of Africa by Daniel de la Feuille. Depicts the continent of Africa form an early 18th century perspective. The Niger River is mapped with surprising accuracy, especially considering its highly inaccurate mappings nearly 100 years later in the 19th century. The Mountains of the Moon, supposed source of the Nile, are located considerably south of where they appear in other maps of the period. Early Ptolemaic maps do note these mountains as well as two large lakes just to the north. Though the Mountains are present, both of these lakes are absent indicating an interesting evolution, away from the Ptolemaic conception, in African cartography. In southern Africa to large empires are named, Monoemugi and Monomotapa. This is the great southern African gold mining region and these names are likely taken from the names of prominent Congolese tribal rulers. Surrounding the map are the curious addition of twelve armorial crests. Crests include those of both Arab and African powers in the region including: Barbarie (Algier, Tunis, Tripoli, Barca ) Maroc , Egypt, Notolie, Malta, Congo, Nubia, Monomotape, and Nigreitie. Many of these kingdoms and their associated armorial crests are purely conjectural. Ethiopia for example is indicated as distinct from Abyssinia with two separate crests, both unrelated to any actual crests that the kingdom seems to have used. The allegorical title cartouche in the upper right quadrant features several Africans cooking over a fire while an Impala or Antelope looks on. This map was originally prepared for inclusion as chart no. 5 in the 1702 edition of De la Feuille's Atlas Portatif. This map is from the later, 1710 edition.

Edmond Halley, 1656-1742, Astronomer Royal RMG BHC2734.tiff
Edmond Halley, 1656-1742, Astronomer Royal

(Updated, March 2014) A half-length portrait to the left, showing Halley in a brown velvet coat, white neck-cloth and periwig. Best known for the comet bearing his name, which returned as he predicted in 1758, Edmond Halley worked on a wide range of scientific problems before becoming Astronomer Royal in 1720, at the age of 64.

Halley began a degree at Queen's College, Oxford, but he left without graduating, having obtained a letter from the king, and financial backing from his father (a wealthy businessman), to sail with the East India Company to St Helena. It was on St Helena that he compiled his 341-star catalogue of the southern skies. He also made observations of the transit of Mercury and suggested how these observations might be used with others to calculate the distance of Mercury and the Sun from the Earth. From 1684 Halley persuaded Newton to publish his most important work, the 'Principia' (1687). He was made a captain in the Royal Navy in 1698 and set off in command of the ship 'Paramore' to investigate (unsuccessfully) using the angular difference between true and magnetic north to calculate longitude. He used the 'Paramore' once more in 1701 to perform investigations into tides in the English Channel, before becoming Professor of Geometry at Oxford in 1703. In 1715 Halley produced a pamphlet showing his predictions for the path of the forthcoming solar eclipse, creating public interest in the event. He used reports made form these numerous observers to refine his calculations and thus produced a more accurate map for the path of the 1724 eclipse which also passed across the UK. In 1720, after Flamsteed's death in 1719, he succeeded him as Astronomer Royal and re-equipped the Royal Observatory at Greenwich with a grant from the Board of Ordnance (since Flamsteed's widow had removed all the equipment and furniture there, regarding it as her late husband's property). Now that there was a good star catalogue, Halley saw his main task as improving the accuracy of the lunar tables. These measurements were, however, lacking in accuracy and, though they were eventually published, their limitations soon became obvious.

Halley is buried in St Margaret's churchyard, Lee, London, SE12. When it became necessary to replace his original (Latin-inscribed) tombstone there, it was restored and remounted in the wall of the east pavilion of Flamsteed House at the Observatory, where it can still be seen. This portrait has been reduced in size, but it is very likely that the mezzotint (see PAF3352) which G. White published in 1721, after Halley became Astronomer Royal, is based on it. The painting itself may be rather earlier and would originally have measured 30 x 25 inches (760 x 635 mm). It was purchased by the Museum from the Sabin Galleries, London, in 1968.

Iceberg A22A, South Atlantic Ocean.jpg
This astronaut photograph illustrates the remains of a giant iceberg—designated A22A— that broke off Antarctica in 2002. The iceberg was photographed at a location of 49.9 degrees south latitude, 23.8 degrees west longitude, which is about a third of the distance from South America towards Cape Town, South Africa. A22A is one of the largest icebergs to drift as far north as 50 degrees south latitude, bringing it beneath the daylight path of the International Space Station (ISS). Crew members aboard the ISS were able to locate the ice mass and photograph it, despite the great masses of clouds that often accompany winter storms in the Southern Ocean. The crew’s viewing angle was oblique (not looking straight down) from a point to the west of the berg, and the time of day was early afternoon, as shown by the orientation of the cloud shadows. Dimensions of A22A in early June were 49.9 by 23.4 kilometres, giving it an area of 622 square kilometres, or seven times the area of Manhattan Island.
