Dead Sea in the context of "Halobacterium"

The Messinian salinity crisis (also referred to as the Messinian event, and in its latest stage as the Lago Mare event) was an event in which the Mediterranean Sea went into a cycle of partial or nearly complete desiccation (drying-up) throughout the latter part of the Messinian age of the Miocene epoch, from 5.96 to 5.33 Ma (million years ago). It ended with the Zanclean flood, when the Atlantic reclaimed the basin.

Sediment samples from below the deep seafloor of the Mediterranean Sea, which include evaporite minerals, soils, and fossil plants, show that the precursor of the Strait of Gibraltar closed about 5.96 million years ago, sealing the Mediterranean off from the Atlantic. This resulted in a period of partial desiccation of the Mediterranean Sea, the first of several such periods during the late Miocene. After the strait closed for the last time around 5.6 Ma, the region's generally dry climate at the time dried the Mediterranean basin out nearly completely within a thousand years. This massive desiccation left a deep dry basin, reaching 3 to 5 km (1.9 to 3.1 mi) deep below normal sea level, with a few hypersaline pockets similar to today's Dead Sea. Then, around 5.5 Ma, wetter climatic conditions resulted in the basin receiving more fresh water from rivers, progressively filling and diluting the hypersaline lakes into larger pockets of brackish water (much like today's Caspian Sea). The Messinian salinity crisis ended with the Strait of Gibraltar finally reopening 5.33 Ma, when the Atlantic rapidly filled up the Mediterranean basin in what is known as the Zanclean flood.

Israel, officially the State of Israel, is a country in the Southern Levant region of West Asia. It borders Lebanon to the north, Syria to the northeast, Jordan to the east and Egypt to the southwest. Israel occupies the Palestinian territories of the West Bank in the east and the Gaza Strip in the southwest, as well as the Syrian Golan Heights in the northeast. Israel's western coast lies on the Mediterranean Sea, the southern tip reaches the Red Sea, and the east includes the Earth's lowest point near the Dead Sea. Jerusalem is the government seat and proclaimed capital, while Tel Aviv is Israel's largest urban area and economic centre.

The Land of Israel is synonymous with Palestine or the Holy Land. In antiquity it was home to the Canaanites and later the kingdoms of Israel and Judah. Its location at a continental crossroads brought demographic shifts under various empires. Nineteenth-century European antisemitism fuelled the Zionist movement for a Jewish homeland. Britain endorsed this goal in the 1917 Balfour Declaration and ruled Mandatory Palestine from 1920. Jewish immigration and British policies intensified Arab-Jewish tensions, and the 1947 United Nations (UN) Partition Plan led to a civil war.

Jordan, officially the Hashemite Kingdom of Jordan, is a country in the Southern Levant region of West Asia. Jordan is bordered by Syria to the north, Iraq to the east, Saudi Arabia to the south, and both Israel and Palestine (West Bank) to the west. The Jordan River, flowing into the Dead Sea, is located along the country's western border within the Jordan Rift Valley. Jordan has a small coastline along the Red Sea in its southwest, separated by the Gulf of Aqaba from Egypt. Amman is the country's capital and largest city, as well as the most populous city in the Levant.

Inhabited by humans since the Paleolithic period, three kingdoms developed in Transjordan during the Iron Age: Ammon, Moab and Edom. In the third century BC, the Arab Nabataeans established their kingdom centered in Petra. The Greco-Roman period saw the establishment of several cities in Transjordan that comprised the Decapolis. After the end of Byzantine rule, the region became part of the Islamic caliphates of the Rashidun, Umayyad, Abbasid, and the Ottoman. Following the 1916 Great Arab Revolt during World War I, former Ottoman Syria was partitioned, leading to the establishment of the Emirate of Transjordan in 1921, which became a British protectorate. In 1946, Jordan gained independence and became officially known as the Hashemite Kingdom of Jordan. Jordan captured and annexed the West Bank during the 1948 Palestine war until it was occupied by Israel in 1967. Jordan renounced its claim to the territory to the Palestinians in 1988 and signed a peace treaty with Israel in 1994.

Jerusalem is a city in the Southern Levant, on a plateau in the Judaean Mountains between the Mediterranean and the Dead Sea. It is one of the oldest cities in the world, and is considered holy to the three major Abrahamic religions—Judaism, Christianity and Islam. Both Israel and Palestine claim Jerusalem as their capital city; Israel maintains its primary governmental institutions there, while Palestine ultimately foresees it as its seat of power. Neither claim is widely recognised internationally.

Throughout its long history, Jerusalem has been destroyed at least twice, besieged 23 times, captured and recaptured 44 times, and attacked 52 times. The part of Jerusalem called the City of David shows first signs of settlement in the 4th millennium BCE, in the shape of encampments of nomadic shepherds. During the Canaanite period (14th century BCE) Jerusalem was named as Urusalim on ancient Egyptian tablets, probably meaning "City of Shalem" after a Canaanite deity. During the Israelite period, significant construction activity in Jerusalem began in the 10th century BCE (Iron Age II), and by the 9th century BCE the city had developed into the religious and administrative centre of the Kingdom of Judah. In 1538 the city walls were rebuilt for a last time around Jerusalem under Suleiman the Magnificent of the Ottoman Empire. Today those walls define the Old City, which since the 19th century has been divided into four quarters—the Armenian, Christian, Jewish and Muslim quarters. The Old City became a World Heritage Site in 1981, and is on the List of World Heritage in Danger. Since 1860 Jerusalem has grown far beyond the Old City's boundaries. In 2023 Jerusalem had a population of 1,028,366. In 2022 60% were Jews and almost 40% were Palestinians. In 2020 the population was 951,100, of which Jews comprised 570,100 (59.9%), Muslims 353,800 (37.2%), Christians 16,300 (1.7%) and 10,800 unclassified (1.1%).

An evaporite (/ɪˈvæpəˌraɪt/) is a water-soluble sedimentary mineral deposit that results from concentration and crystallization by evaporation from an aqueous solution. There are two types of evaporite deposits: marine, which can also be described as ocean deposits, and non-marine, which are found in standing bodies of water such as lakes. Evaporites are considered sedimentary rocks and are formed by chemical sediments.

A meander is one of a series of regular sinuous curves in the channel of a river or other watercourse. It is produced as a watercourse erodes the sediments of an outer, concave bank (cut bank or river cliff) and deposits sediments on an inner, convex bank which is typically a point bar. The result of this coupled erosion and sedimentation is the formation of a sinuous course as the channel migrates back and forth across the axis of a floodplain.

The zone within which a meandering stream periodically shifts its channel is known as a meander belt. It typically ranges from 15 to 18 times the width of the channel. Over time, meanders migrate downstream, sometimes in such a short time as to create civil engineering challenges for local municipalities attempting to maintain stable roads and bridges.

The Southern Levant is a geographical region that corresponds approximately to present-day Israel, Palestine, and Jordan; some definitions also include southern Lebanon, southern Syria and the Sinai Peninsula. As a strictly geographical description, it is sometimes used by archaeologists and historians to avoid the religious and political connotations of other names for this area.

Like much of Southwestern Asia, the Southern Levant is an arid region consisting mostly of desert and dry steppe, with a thin strip of wetter, temperate climate along the Mediterranean coast. Geographically it is dominated by the Jordan Valley, a section of the Great Rift Valley bisecting the region from north to south, and containing the Sea of Galilee, the Jordan River and the Dead Sea—the lowest point on the Earth's land surface.

The West Bank is on the western bank of the Jordan River and is the larger of the two Palestinian territories (the other being the Gaza Strip) that make up the State of Palestine. A landlocked territory near the coast of the Mediterranean Sea in West Asia's Levant region, it is bordered by Jordan and the Dead Sea to the east and by Israel (via the Green Line) to the south, west, and north. Since 1967, the territory has been under Israeli occupation, which has been regarded as illegal under the law of the international community.

The territory first emerged in the wake of the 1948 Arab–Israeli War as a region occupied and subsequently annexed by Jordan. Jordan ruled the territory until the 1967 Six-Day War, when it was occupied by Israel. Since then, Israel has administered the West Bank (except for East Jerusalem, which was effectively annexed in 1980) as the Judea and Samaria Area. Jordan continued to claim the territory as its own until 1988. The mid-1990s Oslo Accords split the West Bank into three regional levels of Palestinian sovereignty, via the Palestinian National Authority (PNA): Area A (PNA), Area B (PNA and Israel), and Area C (Israel, comprising 60% of the West Bank). The PNA exercises total or partial civil administration over 165 Palestinian enclaves across the three areas.

The Jordan River or River Jordan (Arabic: نَهْر الْأُرْدُنّ, Nahr al-ʾUrdunn; Hebrew: נְהַר הַיַּרְדֵּן, Nəhar hayYardēn), also known as Nahr Al-Sharieat (Arabic: نهر الشريعة), is a 251-kilometre-long (156 mi) endorheic river in the Levant that flows roughly north to south through the Sea of Galilee and drains to the Dead Sea. The river passes by or through Jordan, Syria, Israel, and the Palestinian territories.

Jordan and the Israeli-occupied Golan Heights border the river to the east, while Israel and the Israeli-occupied West Bank lie to its west. Both Jordan and the West Bank derive their names in relation to the river. The river holds major significance in Judaism and Christianity. According to the Bible, the Israelites crossed it into the Promised Land and Jesus of Nazareth was baptized by John the Baptist in it.
