Huge Dust Storm Blows Off Coast of Turkey

Dust off Northern Coast of Turkey - October 13th, 2009

A plume of dust originating in southern Turkey archs northwards, across the country and over the Black Sea, into Georgia and southern Russia. The plume fans out as it moves to the north, covering much of the eastern end of the sea.

In the full image, dust hovers over Syria as well. Although it remains clear of Lake Assad, it seems to follow the path of the Euphrates river, past its confluence with the Khabur River, towards Iraq.

Of particular interest in this image, which spans from the Kurdish Mountains in eastern Turkey (above) to the Khabur River basin in northern Syria (below), is the Karaca Volcano, whose peak appears brown encircled by light green at the center left.

Karaca is a broad, 1957-meter-high basaltic shield volcano in southeastern Turkey about 100 km north of the Syrian border. The volcano lies on the Arabian foreland about 150 km southwest of the boundary with the Anatolian Plate and has been active since the Pliocene along a north-to-south trending set of fissures and craters. Some lava flows, particularly those on the east flank, may perhaps be only a few thousand years old.

South of the volcano is an agricultural district, Ceylanpınar, on the border with Syria. To the southeast, more agriculture can be seen in the Khabur Valley across the Syrian border. These fields are irrigated thanks to work from the Khabur River Project, begun in the 1960s, which involved the construction of a series of dams and canals.

The Khabur Valley, which now has about four million acres (16,000 km²) of farmland, is Syria’s main wheat-cultivation area. The northeastern part is also the center for Syria’s oil production.

Detail of the confluence of the Euphrates and Khabur Rivers

The Euphrates is the western of the two great rivers that define Mesopotamia (the other being the Tigris) which flows from Anatolia. The river is approximately 2,781 kilometers (1,730 mi) long.

In the main image on the left, we can see a part of the Euphrates River that runs down from Turkey and across Syria. The Turkish-Syrian border is visible in the upper portion of the image as a change in terrain and color. On the left we have Lake Assad (Buhayrat al Asad) in Syria, and in the top left corner, the Ataturk Dam in Turkey. Slightly right of the center is the confluence of the Euphrates and Khabur Rivers, near the town of Busayrah. Along the river we see green patches hugging the banks; these is mostly from agriculture.

The Euphrates River is formed by the union of two branches: the Kara Su and the Murat Nehri. Their courses run fairly parallel in a westerly direction until they unite near the city of Keban, at an elevation of about 610 m (2,000 ft) above sea level. From this point on, the combined streams form the Euphrates proper.

The upper reaches of the Euphrates flow through steep canyons and gorges, southeast across Syria, and through Iraq. The Khabur (see close-up) and the Balikh River join the Euphrates in eastern Syria. The Euphrates finally emerges on the Syrian plain at a point north of the site of ancient Carchemish (modern Jerablus). Both rivers have their origins in Turkey.

Downstream, through its whole length, the Euphrates has no other notable tributaries. North of Basra, in southern Iraq, the river merges with the Tigris to form the Shatt al-Arab, this in turn empties into the Persian Gulf.

The river used to divide into many channels at Basra, forming an extensive marshland, but the marshes were largely drained by the Saddam Hussein government in the 1990s as a means of driving out the rebellious Marsh Arabs. Since the 2003 invasion of Iraq, the drainage policy has been reversed, but it remains to be seen whether the marshes will recover.

The Euphrates is only navigable by very shallow-draft boats, which can reach as far as the Iraqi city of Hit, located 1,930 kilometers (1,200 mi) upstream and only 60 meters (200 ft) above sea level. Above Hit, however, shoals and rapids make the river commercially unnavigable. Its annual inundation, caused by snow melt in the mountains of northeastern Turkey, has been partly checked by new dams and reservoirs in the upper reaches. An 885-kilometer (550 mi) canal links the Euphrates to the Tigris to serve as a route for river barges.
