Summary

The Red Sea is a crucial seawater inlet of the Indian Ocean, geographically positioned between Africa and Asia. It serves as a vital maritime link, connecting to the broader ocean through the Bab-el-Mandeb Strait and the Gulf of Aden to the south, and extending northward to the Sinai Peninsula, the Gulf of Aqaba, and the Gulf of Suez, which leads to the Suez Canal. Geologically, it is a part of the Great Rift Valley, underlain by the Red Sea Rift. Spanning approximately 438,000 square kilometers, it is about 2,250 kilometers long with a maximum width of 355 kilometers and an average depth of 490 meters, reaching its deepest point at 3,040 meters in the Suakin Trough. Renowned for its extensive shallow shelves, the Red Sea is a biodiversity hotspot, hosting over 1,000 invertebrate species and 200 types of coral, making it the world's northernmost tropical sea and a designated Global 200 ecoregion. Its high salinity, averaging 40‰, is due to high evaporation and low freshwater input. Historically, it has been a significant trade route, used for Egyptian maritime commerce as early as 2000 BC. More recently, the Red Sea gained political prominence in the 'Signalgate' incident, where a secret group chat discussing military action against Houthi rebels in the region was accidentally exposed.

Red Sea

The Red Sea is a sea inlet of the Indian Ocean, lying between Africa and Asia. Its connection to the ocean is in the south, through the Bab-el-Mandeb Strait and the Gulf of Aden. To its north lie the Sinai Peninsula, the Gulf of Aqaba, and the Gulf of Suez—leading to the Suez Canal. It 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 (169,000 sq mi), is about 2,250 km (1,400 mi) long, and 355 km (221 mi) wide at its widest point. It has an average depth of 490 m (1,610 ft), and in the central Suakin Trough, it reaches its maximum depth of 3,040 m (9,970 ft). Approximately 40% of the Red Sea is quite shallow at less than 100 m (330 ft) deep and about 25% is less than 50 m (160 ft) deep. The extensive shallow shelves are noted for their marine life and corals. More than 1,000 invertebrate species and 200 types of soft and hard coral live in the sea. The Red Sea is the world's northernmost tropical sea and has been designated a Global 200 ecoregion.

    The Red Sea is one of the first large bodies of water mentioned in recorded history. The waterway was used for Egyptian maritime commerce about 2000 bc. Some shallow canals were dug between the Nile River and the Red Sea in ancient times but were later abandoned. For centuries cargo was carried over land by camel caravans from the Gulf of Aqaba to the Mediterranean Sea. It was not until 1869 that the Suez Canal was cut across the isthmus, greatly facilitating trade and transportation on the Red [...] The Red Sea is bordered by Egypt, Sudan, and Eritrea on the west and Saudi Arabia and Yemen on the east. The Red Sea occupies an area of about 174,000 square miles (450,000 square kilometers). From a maximum width of 190 miles (306 kilometers), it narrows to 20 miles (32 kilometers) at its southern end.

[...] The Red Sea extends from Suez, Egypt, southward for about 1,200 miles (1,930 kilometers) to the strait of Bab el-Mandeb.

The Gulf of Suez is to the northwest, and the Gulf of Aqaba to the northeast. Between these two gulfs lies the Sinai Peninsula.

    The Red Sea contains some of the world’s hottest and saltiest seawater. With its connection to the Mediterranean Sea via the Suez Canal, it is one of the most heavily traveled waterways in the world, carrying maritime traffic between Europe and Asia. Its name is derived from the colour changes observed in its waters. Normally, the Red Sea is an intense blue-green; occasionally, however, it is populated by extensive blooms of the algae Trichodesmium erythraeum, which, upon dying off, turn the [...] The Red Sea is considered a relatively new sea, whose development probably resembles that of the Atlantic Ocean in its early stages. The Red Sea’s trough apparently formed in at least two complex phases of land motion. The movement of Africa away from Arabia began about 55 million years ago. The Gulf of Suez opened up about 30 million years ago, and the northern part of the Red Sea about 20 million years ago. The second phase began about 3 to 4 million years ago, creating the trough in the Gulf [...] The Red Sea occupies part of a large rift valley in the continental crust of Africa and Arabia. This break in the crust is part of a complex rift system that includes the East African Rift System, which extends southward through Ethiopia, Kenya, and Tanzania for almost 2,200 miles and northward for more than 280 miles from the Gulf of Aqaba to form the great Wadi Aqaba–Dead Sea–Jordan Rift; the system also extends eastward for 600 miles from the southern end of the Red Sea to form the Gulf of
