The length of the gulf, from its mouth at the Strait of Gubal (alternate name: Strait of Jubal) to its head at the city of Suez, is 195 miles (314 km), and it varies in width from 12 to 20 miles (19 to 32 km). The International Hydrographic Organization defines

156-599: A Greek periplus written by an unknown author around the 1st century, contains a detailed description of the Red Sea's ports and sea routes. The Periplus also describes how Hippalus first discovered the direct route from the Red Sea to India . 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

234-684: A geography where large deep-water sharks can roam in hundreds of meters of water, yet be within a hundred meters of swimming areas. The Red Sea Project is building highest quality accommodation and a wide range of facilities on the coast line in Saudi Arabia. This will allow people to visit the coastline of the Red Sea by the end of 2022 but will be fully finished by 2030. Tourism to the region has been threatened by occasional terrorist attacks, and by incidents related to food safety standards. Tiran Island Tiran ( Arabic : جزيرة ثيران Jezîret Tīrān , Jazīrat Tīrān ), and Yotvat Island ,

According to a 2016 statement by the Egyptian Cabinet Information and Decision Support Centre, the Egyptian Chief Delegate to the UN had denied any territorial claims on the islands in May 1967, after the then Egyptian President Gamal Abd al-Nasser closed the Straits of Tiran to Israeli shipping (which was considered as a casus belli by Israel to initiate

546-469: Is a Saudi Arabian island that was formerly administered by Egypt . Sovereignty of the two Red Sea islands, Tiran and Sanafir , was ceded officially to Saudi Arabia as part of a maritime border agreement between Egypt and Saudi Arabia. The agreement was subsequently approved by the Egyptian Parliament and finally ratified by President Abd el-Fattah el-Sisi on 24 June 2017. The island

624-849: Is a direct translation of the Ancient Greek Erythra Thalassa ( Ἐρυθρὰ Θάλασσα ). The sea itself was once referred to as the Erythraean Sea by Europeans. As well as Mare Rubrum in Latin (alternatively Sinus Arabicus , literally "Arabian Gulf"), the Romans called it Pontus Herculis (Sea of Hercules). Other designations include the Arabic : البحر الأحمر , romanized :  Al-Baḥr Al-Aḥmar (alternatively بحر القلزم Baḥr Al-Qulzum , literally "the Sea of Clysma "),

702-480: Is considered that it 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 . Lake Asal in Djibouti

780-447: Is eligible as an experimental site to study the evolution of the deep hot brines of the Red Sea. By observing the strontium isotope composition of the Red Sea brines, it is possible to deduce how these salt waters found at the bottom of the Red Sea could have evolved in a similar way to Lake Asal, which ideally represents their compositional extreme. The high salinity of the waters was not hospitable to living organisms. Sometime during

Since it is no longer a residential bishopric, Iotabe, in its Latin form called Iotapa in Palaestina, is today listed by the Roman Catholic Church as a titular see . The reference by Procopius to an autonomous Jewish community on the island of Iotabe until the 6th century figured in Israeli rhetoric during

1014-554: Is that some Asiatic languages used color words to refer to the cardinal directions . Herodotus on one occasion uses Red Sea and Southern Sea interchangeably. The name in Hebrew Yam Suph ( Hebrew : ים סוף , lit.   'Sea of Reeds') is of biblical origin.

The gulf sedimentary basin stratigraphic section consists of prerift Paleozoic to Oligocene clastic rocks and carbonates , and synrift and postrift Miocene to Holocene clastics and evaporites . Three large oil fields are in

1170-416: Is the driving force in the Red Sea to transport material as suspension or as bedload. Wind-induced currents play an important role in the Red Sea in resuspending bottom sediments and transferring 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

1248-473: The 2023-2024 Israel-Hamas war . One ship was hijacked and taken back to Yemen. The Red Sea is between arid land, desert and semi-desert . Reef systems are better developed along the Red Sea mainly 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 resulting change in biodiversity, without precedent in human memory, is currently accelerating, in particular for fishes according to surveys engaged by the Mediterranean Science Commission . The rich diversity of the Red Sea 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 island has been designated an Important Bird Area (IBA) by BirdLife International because it supports breeding white-eyed gulls . Tiran may be the island that Procopius called Iotabe (in Greek : Ἰωτάβη ), which was an important toll station for shipping in

1560-601: The Red Sea slave trade from Africa to the Middle East. During the Middle Ages , the Red Sea was an important part of the spice trade route. In 1183, Raynald of Châtillon launched a raid down the Red Sea to attack the Muslim pilgrim convoys to Mecca. The possibility that Raynald's fleet might sack the holy cities of Mecca and Medina caused fury throughout the Muslim world. However, it appears that Reynald's target

1638-810: 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 to piracy. Iranian -backed Yemini Houthis have attacked Western ships, including warships , during

In that version, the Yam Suph ( Hebrew : ים סוף , lit.   'Sea of Reeds') is translated as Erythra Thalassa (Red Sea). 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

1794-539: The Six-Day War ): "Egypt did not seek at any time to claim that the sovereignty of the two islands has been transferred to it. Rather Egypt sought only to take over defending the two islands." Shortly thereafter Tiran Island was captured by Israeli Defence Forces troops during the Six-Day War. In January 1968, the US government stood behind a failed attempt to induce Israeli withdrawal from that island as an opening move to

1872-480: The Six-Day War . Tiran Island is of strategic significance in the area, as it forms the narrowest section of the Straits of Tiran, which is an important sea passage to the major ports of Aqaba in Jordan and Eilat in Israel . Israel briefly took over Tiran Island during the Suez Crisis and again from 1967 to 1982 following the Six-Day War. The island is inhabited only by military personnel from Egypt and

1950-788: 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 have been: A number of volcanic islands rise from the center of the sea. Most are dormant. However, in 2007, Jabal al-Tair island in the Bab el Mandeb strait erupted violently. Two new islands were formed in 2011 and 2013 in the Zubair Archipelago , a small chain of islands owned by Yemen. The first island, Sholan Island, emerged in an eruption in December 2011,

2028-692: 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 . 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

2106-968: The global economy , with cargo vessels traveling between the Indian Ocean and the Mediterranean Sea every year, thus shortening the path between Asia and Europe almost by half (as compared to traveling around Africa via the Atlantic Ocean). 12% of global trade passes through the Red Sea. This includes 30% of global container traffic. The sea is known for its recreational diving sites, such as Ras Mohammed , SS Thistlegorm (shipwreck), Elphinstone Reef , The Brothers , Daedalus Reef , St. John's Reef , Rocky Island in Egypt and less known sites in Sudan such as Sanganeb , Abington , Angarosh and Shaab Rumi .

5304-437: 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 flooding

5382-404: The southern limit of the gulf as "A line running from Ras 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". The Gems Field was discovered in 1869, but did not produce until 1910. The Hurghada Field produced in 1913. By 1998, over 1900 wells had been drilled and 120 fields identified. The major oil source rock

5460-402: The southern part and 41 ‰ in the northern part around the Gulf of Suez , with an average of 40 ‰. (Average salinity for the world's seawater is ~35 ‰ on the Practical Salinity Scale, or PSU; that translates to 3.5% of actual dissolved salts). 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

5538-418: The structure of the basin. Normal faults are common as the Red Sea occupies an active diverging margin. These targets are commonly found below the Salt deposits of the Middle Miocene . Modern development is focused on the following fields. The Durwara 2 Field was discovered in 1963, while the Suakin 1 Field and the Bashayer 1A Field were discovered in 1976, on the Egyptian side of the Red Sea. The Barqan Field

5616-441: The territory of Egypt since they have been under Egypt's administration since 1906. In March 1949, Israeli forces took control of the area around the coastal village of Umm al-Rashrash , later renamed Eilat , as part of Operation Uvda . The uninhabited islands of Tiran and Sanafir gained strategic importance since they controlled all shipping to Eilat, Israel's only access to the Red Sea. In May 1948, Egypt blocked passage through

5694-442: The unique properties of these coral and their commensal algae to see if they can be used to salvage bleached coral elsewhere. The Red Sea is one of the saltiest bodies of water in the world, owing to high evaporation and low precipitation; no significant rivers or streams drain into the sea, and its southern connection to the Gulf of Aden , an arm of the Indian Ocean, is narrow. Its salinity ranges from between ~36  ‰ in

5772-481: 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). Temperature and visibility remain good to around 200 m (660 ft). The sea is known for its strong winds and unpredictable local currents. The rainfall over

5850-514: Was closed to all swimming in December 2010 due to several serious shark attacks , including a 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 narrowness, significant depth, and sharp drop-offs, all combine to form

5928-481: Was constructed in the 19th century and continues to be one of the world's most important waterways. The construction of the canal during Darius's reign is evidenced by ancient records, including inscriptions. Darius commemorated the completion of the canal by creating stelae (stone monuments) with inscriptions in several languages, describing the construction and its benefits. The canal not only facilitated trade but also solidified Darius's control over Egypt and enhanced

6006-736: Was discovered in 1969, and the Midyan Field in 1992, both within the Midyan Basin on the Saudi Arabian side of the Red Sea. The 20-m thick Middle Miocene Maqna Formation is an oil source rock in the basin. Oil seeps occur near the Farasan Islands , the Dahlak Archipelago , along the coast of Eritrea, and in the southeastern Red Sea along the coasts of Saudi Arabia and Yemen. In terms of mineral resources

6084-399: Was the lightly armed Muslim pilgrim convoys, rather than the well guarded cities of Mecca and Medina, and the belief in the Muslim world that Reynald was seeking to sack the holy cities, due to the proximity of those cities to the areas that Raynald raided. In 1513, trying to secure that channel to Portugal, Afonso de Albuquerque laid siege to Aden but was forced to retreat. They cruised
