Robert Sténuit
Robert Pierre André Sténuit (16 July 1933 – 9 December 2024) was a Belgian journalist, writer, and underwater archeologist. In 1962, he spent 24 hours on the floor of the Mediterranean Sea in the submersible "Link Cylinder" developed by Edwin Link, thus becoming the world's first aquanaut. Life and career Sténuit was born in Brussels on 16 July 1933. He began caving at the age of seventeen. He discovered diving in 1953 when he began scuba diving in flooded caves in Belgium. He subsequently became interested in speleology and went on to spend many years exploring the Caves of Han-sur-Lesse. Sténuit had a passion for history. At the age of 20, after reading ''600 Milliards Sous les Mers'' bHarry Reiseberg a work of fiction about shipwrecks and treasure diving, Sténuit left the Free University of Brussels, where he was studying political and diplomatic science in preparation for a career as a lawyer. In 1954, Sténuit began looking for the treasures of the Spanish fl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Underwater
An underwater environment is a environment of, and immersed in, liquid water in a natural or artificial feature (called a Water, body of water), such as an ocean, sea, lake, pond, reservoir, river, canal, or aquifer. Some characteristics of the underwater environment are universal, but many depend on the local situation. Liquid water has been present on Earth for most of the History of Earth, history of the planet. The underwater environment is thought to be the place of the origin of life on Earth, and it remains the ecological region most critical to the support of life and the natural habitat of the majority of living organisms. Several branches of science are dedicated to the study of this environment or specific parts or aspects of it. A number of human activities are conducted in the more accessible parts of the underwater environment. These include research, underwater diving for work or recreation, and underwater warfare with submarines. It is hostile to humans in many ...

Helium
Helium (from ) is a chemical element; it has chemical symbol, symbol He and atomic number 2. It is a colorless, odorless, non-toxic, inert gas, inert, monatomic gas and the first in the noble gas group in the periodic table. Its boiling point is the lowest among all the Chemical element, elements, and it does not have a melting point at standard pressures. It is the second-lightest and second-most Abundance of the chemical elements, abundant element in the observable universe, after hydrogen. It is present at about 24% of the total elemental mass, which is more than 12 times the mass of all the heavier elements combined. Its abundance is similar to this in both the Sun and Jupiter, because of the very high nuclear binding energy (per nucleon) of helium-4 with respect to the next three elements after helium. This helium-4 binding energy also accounts for why it is a product of both nuclear fusion and radioactive decay. The most common isotope of helium in the universe is helium-4, ...

The bay ('' rade'') of Villefranche is one of the deepest natural harbours of any port in the Mediterranean Sea and provides safe anchorage for large ships from easterly winds. Reaching depths of between the Cape of Nice and Cap Ferrat, it extends to the south to form a abyss known as the undersea Canyon of Villefranche about off the coastline.

Underwater Habitat
Underwater habitats are underwater structures in which people can live for extended periods and carry out most of the Circadian rhythm, basic human functions of a 24-hour day, such as working, resting, eating, attending to personal hygiene, and sleeping. In this context, 'habitat' is generally used in a narrow sense to mean the interior and immediate exterior of the structure and its fixtures, but not its surrounding ocean, marine environment. Most early underwater habitats lacked regenerative systems for air, water, food, electricity, and other resources. However, some underwater habitats allow for these resources to be delivered using pipes, or generated within the habitat, rather than manually delivered. An underwater habitat has to meet the needs of human physiology and provide suitable Natural environment, environmental conditions, and the one which is most critical is breathing gas of suitable quality. Others concern the physical environment (pressure, temperature, light, h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Treasure
Treasure (from from Greek ''thēsauros'', "treasure store") is a concentration of wealth — often originating from ancient history — that is considered lost and/or forgotten until rediscovered. Some jurisdictions legally define what constitutes treasure, such as in the British Treasure Act 1996. The phrase "blood and treasure" has been used to refer to the human and monetary costs associated with massive endeavours such as war that expend both. Searching for hidden treasure is a common theme in legend; treasure hunters do exist, and can seek lost wealth for a living. Burial Buried treasure is an important part of the popular mythos surrounding pirates. According to popular conception, pirates often buried their stolen fortunes in remote places, intending to return for them later (often with the use of treasure maps). There are three well-known stories that helped popularize the myth of buried pirate treasure: " Wolfert Webber" (1824) by Washington Irving, " The Gold- ...

Battle Of Vigo Bay
The Battle of Vigo Bay, also known as the Battle of Rande (; ), was a naval engagement fought on 23 October 1702 during the opening years of the War of the Spanish Succession. The engagement followed an Anglo-Dutch attempt to capture the Spanish port of Cádiz in September in an effort to secure a naval base in the Iberian Peninsula. From this station the Allies had hoped to conduct operations in the western Mediterranean Sea, particularly against the French at Toulon. The amphibious assault, however, had proved a disaster, but as Admiral George Rooke retreated home in early October, he received news that the Spanish treasure fleet from America, laden with silver and merchandise, had entered Vigo Bay in northern Spain. Philips van Almonde convinced Rooke to attack the treasure ships, despite the lateness of the year and the fact that the vessels were protected by French ships-of-the-line. The French and Spanish fleet sought safety behind a boom with twin batteries. However, All ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spanish Treasure Fleet
The Spanish treasure fleet, or West Indies Fleet (, also called silver fleet or plate fleet; from the meaning "silver"), was a convoy system of sea routes organized by the Spanish Empire from 1566 to 1790, which linked Spain with its Spanish Empire, territories in the Americas across the Atlantic. The convoys were general purpose cargo fleets used for transporting a wide variety of items, including agricultural goods, lumber, various metal resources such as silver and gold, Gemstone, gems, pearls, spices, sugar, tobacco, silk, and other exotic goods from the overseas territories of the Spanish Empire to the Peninsular Spain, Spanish mainland. Spanish goods such as oil, wine, textiles, books and tools were transported in the opposite direction. The West Indies fleet was the first permanent transatlantic trade route in history. Similarly, the related Manila galleons, Manila galleon trade was the first permanent trade route across the Pacific. The Spanish West and East Indies fleets ...
