The Red Sea is a seawater inlet of the Indian Ocean, lying between Africa and Asia. The connection to the ocean is in the south through the Bab el Mandeb strait and the Gulf of Aden. In the north, there is the Sinai Peninsula, the Gulf of Aqaba, and the Gulf of Suez (leading to the Suez Canal). The Red Sea is a Global 200 ecoregion. The sea is underlain by the Red Sea Rift which is part of the Great Rift Valley.

The Red Sea has a surface area of roughly 438,000 km² (169,100 mi²).^[1][2] It is about 2250 km (1398 mi) long and, at its widest point, 355 km (220.6 mi) wide. It has a maximum depth of 2211 m (7254 ft) in the central median trench, and an average depth of 490 m (1,608 ft). However, there are also extensive shallow shelves, noted for their marine life and corals. The sea is the habitat of over 1,000 invertebrate species, and 200 soft and hard corals. It is the world's northernmost tropical sea.

Extent[link]

The International Hydrographic Organization defines the limits of the Red Sea as follows:^[3]

On the North. The Southern limits of the Gulfs of Suez [A line running from Ràs Muhammed (27°43'N) to the South point of Shadwan Island (34°02'E) and thence Westward on a parallel (27°27'N) to the coast of Africa] and Aqaba [A line running from Ràs al Fasma Southwesterly to Requin Island (27°57′N 34°36′E / 27.95°N 34.6°E / 27.95; 34.6) through Tiran Island to the Southwest point thereof and thence Westward on a parallel (27°54'N) to the coast of the Sinaï Peninsula].

On the South. A line joining Husn Murad (12°40′N 43°30′E / 12.667°N 43.5°E / 12.667; 43.5) and Ras Siyan (12°29′N 43°20′E / 12.483°N 43.333°E / 12.483; 43.333).

Name[link]

Tihama on the Red Sea near Khaukha, Yemen

Red Sea is a direct translation of the Greek Erythra Thalassa (Ερυθρὰ Θάλασσα) and Latin Mare Rubrum (alternatively Sinus Arabicus, literally "Arabian Gulf"), Arabic Al-Baḥr Al-Aḥmar (البحر الأحمر) or Baḥr Al-Qalzam(بحر القلزم), Somali Badda Cas and Tigrinya Qeyyiḥ bāḥrī (ቀይሕ ባሕሪ). The name of the sea may signify the seasonal blooms of the red-coloured Trichodesmium erythraeum near the water's surface.^[4] A theory favored by some modern scholars^[who?] is that the name red is referring to the direction South, just as the Black Sea's name may refer to North. The basis of this theory is that some Asiatic languages used color words to refer to the cardinal directions.^[5] Herodotus on one occasion uses Red Sea and Southern Sea interchangeably.^[6]

Some ancient geographers called the Red Sea the Arabian Gulf^[7] or Gulf of Arabia.^[8][9]

The association of the Red Sea with the Biblical account of the Israelite Crossing the Red Sea is ancient, and was made explicit in the Septuagint translation of the Book of Exodus from Hebrew to Koine Greek in approximately the third century B.C. In that version, the Hebrew Yam Suph (ים סוף) is translated as Erythra Thalassa (Red Sea). (See also the more recent suggestion that the Yam Suph of the Exodus refers to a Sea of Reeds). The Red Sea is one of four seas named in English after common color terms — the others being the Black Sea, the White Sea and the Yellow Sea. The direct rendition of the Greek Erythra thalassa in Latin as Mare Erythraeum refers to the north-western part of the Indian Ocean, and also to a region on Mars.

History[link]

Ancient Egyptian expedition to the Land of Punt on the Red Sea coast.

The earliest known exploration of the Red Sea was conducted by Ancient Egyptians, as they attempted to establish commercial routes to Punt. One such expedition took place around 2500 BC, and another around 1500 BC ( by Hatshepsut ). Both involved long voyages down the Red Sea.^[10] The Biblical Book of Exodus tells the story of the Israelites' miraculous crossing of a body of water, which the Hebrew text calls Yam Suph. Yam Suph is traditionally identified as the Red Sea. The account is part of the Israelites' escape from slavery in Egypt. Yam Suph can also been translated as Sea of Reeds.

In the 6th century BC, Darius the Great of Persia sent reconnaissance missions to the Red Sea, improving and extending navigation by locating many hazardous rocks and currents. A canal was built between the Nile and the northern end of the Red Sea at Suez. In the late 4th century BC, Alexander the Great sent Greek naval expeditions down the Red Sea to the Indian Ocean. Greek navigators continued to explore and compile data on the Red Sea. Agatharchides collected information about the sea in the 2nd century BC. The Periplus of the Erythraean Sea ("Periplus of the Red Sea"), a Greek periplus written by an unknown author around the 1st century AD, contain a detailed description of the Red Sea's ports and sea routes.^[11] The Periplus also describes how Hippalus first discovered the direct route from the Red Sea to India.

Settlements and commercial centers in the vicinity of the Red Sea involved in the spice trade, as described in the Periplus of the Erythraean Sea.

The Red Sea was favored for Roman trade with India starting with the reign of Augustus, when the Roman Empire gained control over the Mediterranean, Egypt, and the northern Red Sea. The route had been used by previous states but grew in the volume of traffic under the Romans. From Indian ports goods from China were introduced to the Roman world. Contact between Rome and China depended on the Red Sea, but the route was broken by the Aksumite Empire around the 3rd century AD.^[12]

During the Middle Ages, the Red Sea was an important part of the Spice trade route. In 1513, trying to secure that channel to Portugal, Afonso de Albuquerque laid siege to Aden.^[13] but was forced to retreat. They cruised the Red Sea inside the Bab al-Mandab, as the first European fleet to have sailed this waters.

In 1798, France ordered General Bonaparte to invade Egypt and take control of the Red Sea. Although he failed in his mission, the engineer Jean-Baptiste Lepère, who took part in it, revitalised the plan for a canal which had been envisaged during the reign of the Pharaohs. Several canals were built in ancient times from the Nile to the Red Sea along or near the line of the present Sweet Water Canal, but none lasted for long. The Suez Canal was opened in November 1869. At the time, the British, French, and Italians shared the trading posts. The posts were gradually dismantled following the First World War. After the Second World War, the Americans and Soviets exerted their influence whilst the volume of oil tanker traffic intensified. However, the Six Day War culminated in the closure of the Suez Canal from 1967 to 1975. Today, in spite of patrols by the major maritime fleets in the waters of the Red Sea, the Suez Canal has never recovered its supremacy over the Cape route, which is believed to be less vulnerable.

Oceanography[link]

Bathymetric map of the Red Sea

The Red Sea lies between arid land, desert and semi-desert. The main reasons for the better development of reef systems along the Red Sea is because of its greater depths and an efficient water circulation pattern, The Red Sea water mass exchanges its water with the Arabian Sea, Indian Ocean via the Gulf of Aden. These physical factors reduce the effect of high salinity caused by evaporation water in the north and relatively hot water in the south.

The climate of the Red Sea is the result of two distinct monsoon seasons; a northeasterly monsoon and a southwesterly monsoon. Monsoon winds occur because of the differential heating between the land surface and sea. Very high surface temperatures coupled with high salinities makes this one of the hottest and saltiest bodies of seawater in the world. The average surface water temperature of the Red Sea during the summer is about 26 °C (79 °F) in the north and 30 °C (86 °F) in the south, with only about 2 °C (3.6 °F) variation during the winter months. The overall average water temperature is 22 °C (72 °F). Today surface water temperatures remain relatively constant at 21–25 °C (70–77 °F). Temperature and visibility remain good to around 200 m (656 ft). The sea is known for its strong winds and unpredictable local currents.

The rainfall over the Red Sea and its coasts is extremely low, averaging 0.06 m (2.36 in) per year. The rain is mostly in the form of showers of short spells, often associated with thunderstorms and occasionally with dust storms. The scarcity of rainfall and no major source of fresh water to the Red Sea result in the excess evaporation as high as 205 cm (81 in) per year and high salinity with minimal seasonal variation. A recent underwater expedition to the Red Sea offshore from Sudan and Eritrea^[14] found surface water temperatures 28 °C in winter and up to 34 °C in the summer, but despite that extreme heat the coral was healthy with much fish life with very little sign of coral bleaching, and there were plans to use samples of these corals' apparently heat-adapted commensal algae to salvage bleached coral elsewhere.

Salinity[link]

The Red Sea is one of the most saline bodies of water in the world, due to high evaporation. Salinity ranges from between ~36 ‰ in the southern part due to the effect of the Gulf of Aden water and reaches 41 ‰ in the northern part, due mainly to the Gulf of Suez water and the high evaporation. The average salinity is 40 ‰. (Average salinity for the world's seawater is ~35 ‰ on the Practical Salinity Scale, or PPS; that translates to 3.5 % actual dissolved salts.)

In terms of salinity, the Red Sea is greater than the world average, approximately 4 percent. This is due to several factors:

1. High rate of evaporation and very little precipitation.
2. Lack of significant rivers or streams draining into the sea.
3. Limited connection with the Indian Ocean, which has lower water salinity.

Tidal range[link]

In general tide ranges between 0.6 m (2.0 ft) in the north, near the mouth of the Gulf of Suez and 0.9 m (3.0 ft) in the south near the Gulf of Aden but it fluctuates between 0.20 m (0.66 ft) and 0.30 m (0.98 ft) away from the nodal point. The central Red Sea (Jeddah area) is therefore almost tideless, and as such the annual water level changes are more significant. Because of the small tidal range the water during high tide inundates the coastal sabkhas as a thin sheet of water up to a few hundred metres rather than inundating the sabkhas through a network of channels. However, south of Jeddah in the Shoiaba area the water from the lagoon may cover the adjoining sabkhas as far as 3 km (2 mi) whereas, north of Jeddah in the Al-kharrar area the sabkhas are covered by a thin sheet of water as far as 2 km (1.2 mi). The prevailing north and northeastern winds influence the movement of water in the coastal inlets to the adjacent sabkhas, especially during storms. Winter mean sea level is 0.5 m (1.6 ft) higher than in summer. Tidal velocities passing through constrictions caused by reefs, sand bars and low islands commonly exceed 1–2 m/s (3–6.5 ft/s). Coral reefs in the Red Sea are near Egypt, Saudi Arabia, Israel and Sudan.

Current[link]

In the Red Sea detailed current data is lacking, partially because they are weak and variable both spatially and temporally. Temporal and spatial currents variation is as low as 0.5 m (1.6 ft) and are governed all by wind. During the summer, NW winds drive surface water south for about four months at a velocity of 15–20 cm/s (6–8 in/s), whereas in winter the flow is reversed resulting in the inflow of water from the Gulf of Aden into the Red Sea. The net value of the latter predominates, resulting in an overall drift to the northern end of the Red Sea. Generally, the velocity of the tidal current is between 50–60 cm/s (20–23.6 in/s) with a maximum of 1 m/s (3.3 ft) at the mouth of the al-Kharrar Lagoon. However, the range of the north-northeast current along the Saudi coast is 8–29 cm/s (3–11.4 in/s).

Wind regime[link]

With the exception of the northern part of the Red Sea, which is dominated by persistent north-west winds, with speeds ranging between 7 km/h (4.3 mph) and 12 km/h (7.5 mph), the rest of the Red Sea and the Gulf of Aden are subjected to the influence of regular and seasonally reversible winds. The wind regime is characterized by both seasonal and regional variations in speed and direction with average speed generally increasing northward.

Wind is the driving force in the Red Sea for transporting the material either as suspension or as bedload. Wind induced currents play an important role in the Red Sea in initiating the process of resuspension of bottom sediments and transfer of materials from sites of dumping to sites of burial in quiescent environment of deposition. Wind generated current measurement is therefore important in order to determine the sediment dispersal pattern and its role in the erosion and accretion of the coastal rock exposure and the submerged coral beds.

Geology[link]

Dust storm over the Red Sea

The Red Sea was formed by Arabia splitting from Africa due to movement of the Red Sea Rift. This split started in the Eocene and accelerated during the Oligocene. The sea is still widening and it is considered that the sea will become an ocean in time (as proposed in the model of John Tuzo Wilson). In 1949, a deep water survey reported anomalously hot brines in the central portion of the Red Sea. Later work in the 1960s confirmed the presence of hot, 60 °C (140 °F), saline brines and associated metalliferous muds. The hot solutions were emanating from an active subseafloor rift. The highly saline character of the waters was not hospitable to living organisms.^[15]

Sometimes during the Tertiary period the Bab el Mandeb closed and the Red Sea evaporated to an empty hot dry salt-floored sink. Effects causing this would be:

• A "race" between the Red Sea widening and Perim Island erupting filling the Bab el Mandeb with lava.
• The lowering of world sea level during the Ice Ages due to much water being locked up in the ice caps.

A number of volcanic islands rise from the center of the sea. Most are dormant, but in 2007 Jabal al-Tair island, in the Bab el Mandeb strait, erupted violently. An eruption among the nearby Zubair islands followed in 2011.^[16]

Mineral resources[link]

Red Sea coast in Taba, Egypt

In terms of mineral resources the major constituents of the Red Sea sediments are as follows:

• Biogenic constituents:

Nanofossils, foraminifera, pteropods, siliceous fossils

• Volcanogenic constituents:

Tuffites, volcanic ash, montmorillonite, cristobalite, zeolites

• Terrigenous constituents:

Quartz, feldspars, rock fragments, mica, heavy minerals, clay minerals

• Authigenic minerals:

Sulfide minerals, aragonite, Mg-calcite, protodolomite, dolomite, quartz, chalcedony.

• Evaporite minerals:

Magnesite, gypsum, anhydrite, halite, polyhalite

• Brine precipitate:

Fe-montmorillonite, goethite, hematite, siderite, rhodochrosite, pyrite, sphalerite, anhydrite.

Living resources[link]

The Red Sea is a rich and diverse ecosystem. More than 1200 species of fish^[17] have been recorded in the Red Sea, and around 10% of these are found nowhere else.^[18] This also includes 42 species of deepwater fish.^[17]

Red Sea coral and marine fish

The rich diversity is in part due to the 2,000 km (1,240 mi) of coral reef extending along its coastline; these fringing reefs are 5000–7000 years old and are largely formed of stony acropora and porites corals. The reefs form platforms and sometimes lagoons along the coast and occasional other features such as cylinders (such as the Blue Hole (Red Sea) at Dahab). These coastal reefs are also visited by pelagic species of red sea fish, including some of the 44 species of shark.

The Red Sea also contains many offshore reefs including several true atolls. Many of the unusual offshore reef formations defy classic (i.e., Darwinian) coral reef classification schemes, and are generally attributed to the high levels of tectonic activity that characterize the area.

The special biodiversity of the area is recognized by the Egyptian government, who set up the Ras Mohammed National Park in 1983. The rules and regulations governing this area protect local marine life, which has become a major draw for diving enthusiasts.

Divers and snorkellers should be aware that although most Red Sea species are innocuous, a few are hazardous to humans: see Red Sea species hazardous to humans.^[19]

Other marine habitats include sea grass beds, salt pans, mangroves and salt marshes.

Desalination plants[link]

There is extensive demand of desalinated water to meet the requirement of the population and the industries along the Red Sea.

There are at least 18 desalination plants along the Red Sea coast of Saudi Arabia which discharge warm brine and treatment chemicals (chlorine and anti-scalants) that may cause bleaching and mortality of corals and diseases to the fish stocks. Although this is only a localized phenomenon, it may intensify with time and have a profound impact on the fishing industry.^[20]

The water from the Red Sea is also utilized by oil refineries and cement factories for cooling purposes. Used water drained back into the coastal zones may cause harm to the nearshore environment of the Red Sea.

Security[link]

The Red Sea is part of the sea roads between Europe, the Persian Gulf and East Asia, and as such has heavy shipping traffic. Piracy in Somalia occurs principally near the area of the Gulf of Aden south of the sea. Government-related bodies with responsibility to police the Red Sea area include the Port Said Port Authority, Suez Canal Authority and Red Sea Ports Authority of Egypt, Jordan Maritime Authority, Israel Port Authority, Saudi Ports Authority and Sea Ports Corporation of Sudan.

Tourism[link]

This unreferenced section requires citations to ensure verifiability.

The sea is known for its spectacular recreational diving sites, such as Ras Mohammed, SS Thistlegorm (shipwreck), Elphinstone, The Brothers, Dolphin Reef and Rocky Island in Egypt and less known sites in Sudan such as Sanganeb, Abington, Angarosh and Shaab Rumi.

The Red Sea became a sought-after diving destination after the expeditions of Hans Hass in the 1950s, and later by Jacques-Yves Cousteau. Popular tourist resorts include El Gouna, Hurghada, Safaga, Marsa Alam, on the western shore of the Red Sea, and Sharm-El-Sheikh, Dahab, and Taba on the Egyptian side of Sinaï, as well as Aqaba in Jordan and Eilat in Israel in an area known as the Red Sea Riviera.

The popular tourist beach of Sharm el-Sheikh was closed to all swimming in December 2010 due to several serious shark attacks, including one fatality. As of December 2010, scientists are investigating the attacks and have identified, but not verified, several possible causes including over-fishing which causes large sharks to hunt closer to shore, tourist boat operators who chum offshore for shark-photo opportunities, and reports of ships throwing dead livestock overboard. The sea's narrow width, significant depth, and sharp drop-offs, all combine to form a geography where large deep-water sharks can roam in hundreds of meters of water, yet be within a hundred meters of swimming areas.

Bordering countries[link]

The Red Sea may be geographically divided into three sections: the Red Sea proper, and in the north, the Gulf of Aqaba and the Gulf of Suez. The six countries bordering the Red Sea proper are:

• Eastern shore:
  •  Saudi Arabia
  •  Yemen
• Western shore:
  •  Egypt
  •  Sudan
  •  Eritrea
  •  Djibouti

The Gulf of Suez is entirely bordered by Egypt. The Gulf of Aqaba borders Egypt, Israel, Jordan and Saudi Arabia.

In addition to the standard geographical definition of the six countries bordering the Red Sea cited above, areas such as Somalia and Ethiopia are sometimes also described as Red Sea territories. This is primarily due to their proximity to and geological similarities with the nations facing the Red Sea and/or political ties with said areas.^[21][22]

Jacques-Yves Cousteau (French pronunciation: [ʒak iv kusto]; commonly known in English as Jacques Cousteau; 11 June 1910 – 25 June 1997)^[1] was a French naval officer, explorer, conservationist, filmmaker, innovator, scientist, photographer, author and researcher who studied the sea and all forms of life in water. He co-developed the Aqua-Lung, pioneered marine conservation and was a member of the Académie française. He was also known as "le Commandant Cousteau" or "Captain Cousteau".

Biography[link]

Early years[link]

Cousteau was born on 11 June 1910, in Saint-André-de-Cubzac, Gironde, France to Daniel and Élisabeth Cousteau. He had one brother, Pierre-Antoine. Cousteau completed his preparatory studies at the prestigious Collège Stanislas in Paris. In 1930, he entered the École Navale and graduated as a gunnery officer. After an automobile accident cut short his career in naval aviation, Cousteau indulged his interest in the sea.

In Toulon, where he was serving on the Condorcet, Cousteau carried out his first underwater experiments, thanks to his friend Philippe Tailliez who in 1936 lent him some Fernez underwater goggles, predecessors of modern swimming goggles.^[2] Cousteau also belonged to the information service of the French Navy, and was sent on missions to Shanghai and Japan (1935–1938) and in the USSR (1939).^{[citation needed]}

On 12 July 1937 he married Simone Melchior, with whom he had two sons, Jean-Michel (born 1938) and Philippe (1940–1979). His sons took part in the adventures of the Calypso. In 1991, one year after his wife Simone's death from cancer, he married Francine Triplet. They already had a daughter Diane Cousteau (born 1980) and a son Pierre-Yves Cousteau (born 1982), born during Cousteau's marriage to his first wife.

Early 1940s: Innovation of modern underwater diving[link]

The years of World War II were decisive for the history of diving. After the armistice of 1940, the family of Simone and Jacques-Yves Cousteau took refuge in Megève, where he became a friend of the Ichac family who also lived there. Jacques-Yves Cousteau and Marcel Ichac shared the same desire to reveal to the general public unknown and inaccessible places — for Cousteau the underwater world and for Ichac the high mountains. The two neighbors took the first ex-aequo prize of the Congress of Documentary Film in 1943, for the first French underwater film: Par dix-huit mètres de fond (18 meters deep), made without breathing apparatus the previous year in the Embiez islands (Var) with Philippe Tailliez and Frédéric Dumas, using a depth-pressure-proof camera case developed by mechanical engineer Léon Vèche (engineer of Arts and Métiers and the Naval College).

In 1943, they made the film Épaves (Shipwrecks), in which they used two of the very first Aqua-Lung prototypes. These prototypes were made in Boulogne-Billancourt by the Air Liquide company, following instructions from Cousteau and Émile Gagnan.^[3][4] When making Épaves, Cousteau could not find the necessary blank reels of movie film, but had to buy hundreds of small still camera film reels the same width, intended for a make of child's camera, and cemented them together to make long reels.^[5][6]

Having kept bonds with the English speakers (he spent part of his childhood in the United States and usually spoke English) and with French soldiers in North Africa (under Admiral Lemonnier), Jacques-Yves Cousteau (whose villa "Baobab" at Sanary (Var) was opposite Admiral Darlan's villa "Reine"), helped the French Navy to join again with the Allies; he assembled a commando operation against the Italian espionage services in France, and received several military decorations for his deeds. At that time, he kept his distance from his brother Pierre-Antoine Cousteau, a "pen anti-semite" who wrote the collaborationist newspaper Je suis partout (I am everywhere) and who received the death sentence in 1946. However this was later commuted to a life sentence, and Pierre-Antoine was released in 1954.

During the 1940s, Cousteau is credited with improving the aqua-lung design which gave birth to the open-circuit scuba technology used today. According to his first book, The Silent World: A Story of Undersea Discovery and Adventure (1953), Cousteau started diving with Fernez goggles in 1936, and in 1939 used the self contained underwater breathing apparatus invented in 1926 by Commander Yves le Prieur.^[7] Cousteau was not satisfied with the length of time he could spend underwater with the Le Prieur apparatus so he improved it to extend underwater duration by adding a demand regulator, invented in 1942 by Émile Gagnan.^[8] In 1943 Cousteau tried out the first prototype aqua-lung which finally made extended underwater exploration possible.

[edit] Late 1940s: GERS and Élie Monnier

In 1946, Cousteau and Tailliez showed the film "Épaves" to Admiral Lemonnier, and the admiral gave them the responsibility of setting up the Groupement de Recherches Sous-marines (GRS) (Underwater Research Group) of the French Navy in Toulon. A little later it became the GERS (Groupe d'Études et de Recherches Sous-Marines, = Underwater Studies and Research Group), then the COMISMER ("COMmandement des Interventions Sous la MER", = "Undersea Interventions Command"), and finally more recently the CEPHISMER. In 1947, Chief Petty Officer Maurice Fargues became the first diver to die using an aqualung while attempting a new depth record with the GERS near Toulon.^[9]

In 1948, between missions of mine clearance, underwater exploration and technological and physiological tests, Cousteau undertook a first campaign in the Mediterranean on board the sloop Élie Monnier,^[10] with Philippe Tailliez, Frédéric Dumas, Jean Alinat and the scenario writer Marcel Ichac. The small team also undertook the exploration of the Roman wreck of Mahdia (Tunisia). It was the first underwater archaeology operation using autonomous diving, opening the way for scientific underwater archaeology. Cousteau and Marcel Ichac brought back from there the Carnets diving film (presented and preceded with the Cannes Film Festival 1951).

Cousteau and the Élie Monnier then took part in the rescue of Professor Jacques Piccard's bathyscaphe, the FNRS-2, during the 1949 expedition to Dakar. Thanks to this rescue, the French Navy was able to reuse the sphere of the bathyscaphe to construct the FNRS-3.

The adventures of this period are told in the two books The Silent World (1953, by Cousteau and Dumas) and Plongées sans câble (1954, by Philippe Tailliez).

1950–1970s[link]

In 1949, Cousteau left the French Navy.

In 1950, he founded the French Oceanographic Campaigns (FOC), and leased a ship called Calypso from Thomas Loel Guinness for a symbolic one franc a year. Cousteau refitted the Calypso as a mobile laboratory for field research and as his principal vessel for diving and filming. He also carried out underwater archaeological excavations in the Mediterranean, in particular at Grand-Congloué (1952).

With the publication of his first book in 1953, The Silent World, he correctly predicted the existence of the echolocation abilities of porpoises. He reported that his research vessel, the Élie Monier, was heading to the Straits of Gibraltar and noticed a group of porpoises following them. Cousteau changed course a few degrees off the optimal course to the center of the strait, and the porpoises followed for a few minutes, then diverged toward mid-channel again. It was evident that they knew where the optimal course lay, even if the humans did not. Cousteau concluded that the cetaceans had something like sonar, which was a relatively new feature on submarines.

Cousteau won the Palme d'Or at the Cannes Film Festival in 1956 for The Silent World co-produced with Louis Malle. With the assistance of Jean Mollard, he made a "diving saucer" SP-350, an experimental underwater vehicle which could reach a depth of 350 meters. The successful experiment was quickly repeated in 1965 with two vehicles which reached 500 meters.

In 1957, he was elected as director of the Oceanographical Museum of Monaco. He directed Précontinent, about the experiments of diving in saturation (long-duration immersion, houses under the sea), and was admitted to the United States National Academy of Sciences.

In October 1960, a large amount of radioactive waste was going to be discarded in the Mediterranean Sea by the Commissariat à l'énergie atomique (CEA). The CEA argued that the dumps were experimental in nature, and that French oceanographers such as Vsevelod Romanovsky had recommended it. Romanovsky and other French scientists, including Louis Fage and Jacques Cousteau, repudiated the claim, saying that Romanovsky had in mind a much smaller amount. The CEA claimed that there was little circulation (and hence little need for concern) at the dump site between Nice and Corsica, but French public opinion sided with the oceanographers rather than with the CEA atomic energy scientists. The CEA chief, Francis Perrin, decided to postpone the dump.^[11] Cousteau organized a publicity campaign which in less than two weeks gained wide popular support. The train carrying the waste was stopped by women and children sitting on the railway tracks, and it was sent back to its origin.

A meeting with American television companies (ABC, Métromédia, NBC) created the series The Underwater Odyssey of Commander Cousteau, with the character of the commander in the red bonnet inherited from standard diving dress) intended to give the films a "personalized adventure" style.

In 1970, he wrote the book The Shark: Splendid Savage of the Sea with Philippe, his son. In this book, Costeau described the oceanic whitetip shark as "the most dangerous of all sharks".

In 1973, along with his two sons and Frederick Hyman, he created the Cousteau Society for the Protection of Ocean Life, Frederick Hyman being its first President; it now has more than 300,000 members.

Three years after the volcano's last eruption, on 19 December 1973, the Cousteau team was filming on Deception Island, Antarctica when Michel Laval, Calypso's second in command, was struck and killed by a propeller of the helicopter that was ferrying between Calypso and the island.

In 1976, Cousteau uncovered the wreck of HMHS Britannic. He also found the wreck of La Therese in Crete island

In 1977, together with Peter Scott, he received the UN International Environment prize.

On 28 June 1979, while the Calypso was on an expedition to Portugal, his second son, Philippe, his preferred and designated successor and with whom he had co-produced all his films since 1969, died in a PBY Catalina flying boat crash in the Tagus river near Lisbon. Cousteau was deeply affected. He called his then eldest son, the architect Jean-Michel Cousteau, to his side. This collaboration lasted 14 years.

1980–1990s[link]

In 1980, Cousteau traveled to Canada to make two films on the Saint Lawrence River and the Great Lakes, Cries from the Deep and St. Lawrence: Stairway to the Sea.^[12]

In 1985, he received the Presidential Medal of Freedom from Ronald Reagan.

On 24 November 1988, he was elected to the French Academy, chair 17, succeeding Jean Delay. His official reception under the Cupola took place on 22 June 1989, the response to his speech of reception being given by Bertrand Poirot-Delpech. After his death, he was replaced under the Cupola by Érik Orsenna on 28 May 1998.

In June 1990, the composer Jean Michel Jarre paid homage to the commander by entitling his new album Waiting for Cousteau. He also composed the music for Cousteau's documentary "Palawan, the last refuge".

On 2 December 1990, his wife Simone Cousteau died of cancer.

In June 1991, in Paris, Jacques-Yves Cousteau remarried, to Francine Triplet, with whom he had (before this marriage) two children, Diane and Pierre-Yves. Francine Cousteau currently continues her husband's work as the head of the Cousteau Foundation and Cousteau Society. From that point, the relations between Jacques-Yves and his elder son worsened.

In November 1991, Cousteau gave an interview to the UNESCO courier, in which he stated that he was in favour of human population control and population decrease. The full article text can be found online.^[13]

In 1992, he was invited to Rio de Janeiro, Brazil, for the United Nations' International Conference on Environment and Development, and then he became a regular consultant for the UN and the World Bank.

In 1996, he sued his son who wished to open a holiday centre named "Cousteau" in the Fiji Islands.

On 11 January 1996, Calypso was rammed and sunk in Singapore Harbour by a barge. The Calypso was refloated and towed home to France.

Death[link]

Jacques-Yves Cousteau died on 25 June 1997 in Paris, aged 87. Despite persistent rumors, encouraged by some Islamic publications and websites, Cousteau did not convert to Islam, and when he died he was buried in a Roman Catholic Christian funeral.^[14] He was buried in the family vault at Saint-André-de-Cubzac in France. An homage was paid to him by the city by the inauguration of a "rue du Commandant Cousteau", a street which runs out to his native house, where a commemorative plaque was affixed.

Honours[link]

During his lifetime, Jacques-Yves Cousteau received these distinctions:

• Commander of the Legion of Honour
• Grand Cross of the National Order of Merit
• Cross of War 1939–1945
• Officer of the Order of Maritime Merit
• Commander of the Order of Arts and Letters
• Honorary Companion of the Order of Australia (26 January 1990)^[15]
• National Geographic Society's Special Gold Medal in 1961^[16]

Legacy[link]

Cousteau's legacy includes more than 120 television documentaries, more than 50 books, and an environmental protection foundation with 300,000 members.^[17]

Cousteau liked to call himself an "oceanographic technician." He was, in reality, a sophisticated showman, teacher, and lover of nature. His work permitted many people to explore the resources of the oceans.

His work also created a new kind of scientific communication, criticised at the time by some academics. The so-called "divulgationism", a simple way of sharing scientific concepts, was soon employed in other disciplines and became one of the most important characteristics of modern television broadcasting.

Cousteau died on 25 June 1997. The Cousteau Society and its French counterpart, l'Équipe Cousteau, both of which Jacques-Yves Cousteau founded, are still active today. The Society is currently attempting to turn the original Calypso into a museum and it is raising funds to build a successor vessel, the Calypso II.

In his last years, after marrying again, Cousteau became involved in a legal battle with his son Jean-Michel over Jean-Michel licensing the Cousteau name for a South Pacific resort, resulting in Jean-Michel Cousteau being ordered by the court not to encourage confusion between his for-profit business and his father's non-profit endeavours.

In 2007, the International Watch Company introduced the IWC Aquatimer Chronograph "Cousteau Divers" Special Edition. The timepiece incorporated a sliver of wood from the interior of Cousteau's Calypso research vessel. Having developed the diver's watch, IWC offered support to The Cousteau Society. The proceeds from the timepieces' sales were partially donated to the non-profit organization involved into conservation of marine life and preservation of tropical coral reefs.^[18]
