Aden (/ˈɑːdɛn/ AH-den; Arabic: عدن ʻAdan) is a seaport city in South Yemen, located by the eastern approach to the Red Sea (the Gulf of Aden), some 170 kilometres east of Bab-el-Mandeb. Its population is approximately a million people. Aden's ancient, natural harbour lies in the crater of a dormant volcano which now forms a peninsula, joined to the mainland by a low isthmus. This harbour, Front Bay, was first used by the ancient Kingdom of Awsan between the 5th and 7th centuries BCE. The modern harbour is on the other side of the peninsula.
Aden consists of a number of distinct sub-centers: Crater, the original port city; Ma'alla, the modern port; Tawahi, known as "Steamer Point" in the colonial period; and the resorts of Gold Mohur. Khormaksar, located on the isthmus that connects Aden proper with the mainland, includes the city's diplomatic missions, the main offices of Aden University, and Aden International Airport (the former British Royal Air Force station RAF Khormaksar), Yemen's second biggest airport. On the mainland are the sub-centres of Sheikh Othman, a former oasis area; Al-Mansura, a town planned by the British; and Madinat ash-Sha'b (formerly Madinat al-Itihad), the site designated as the capital of the South Arabian Federation and now home to a large power/desalinization facility and additional faculties of Aden University.
The Gulf of Aden (Arabic: خليج عدن Ḫalīǧ ʻAdan, Somali: Gacanka Cadmeed) is a gulf located in the Arabian Sea between Yemen, on the south coast of the Arabian Peninsula, and Somalia in the Horn of Africa. In the northwest, it connects with the Red Sea through the Bab-el-Mandeb strait, which is about 20 miles wide.
The waterway is part of the important Suez canal shipping route between the Mediterranean Sea and the Arabian Sea in the Indian Ocean with 21,000 ships crossing the gulf annually. The gulf is known by the nickname "Pirate Alley" due to the large amount of pirate activity in the area.
The International Hydrographic Organization defines the limits of the Gulf of Aden as follows:
On the Northwest. The Southern limit of the Red Sea [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)].
On the East. The meridian of Cape Guardafui (Ras Asir, 51°16'E).
The temperature of the Gulf of Aden varies between 15 °C (59 °F) and 28 °C (82 °F), depending on the season and the appearance of monsoons. The salinity of the gulf at 10 metres (33 ft) depth varies from 35.3 ‰ along the eastern Somali coast to as high as 37.3 ‰ in the gulf's center, while the oxygen content in the Gulf of Aden at the same depth is typically between 4.0 and 5.0 mg/L.
