Algeria - May 23rd, 2011

Green, fertile coastal Algeria gives way to arid terrain as one moves to the lower half of this image. The large, brown area that stands out against the light orange-tan in this part of the image is the Great Sebkha, also known as the Sebkha of Oran.

It is a salt lake in a depression in Algeria distant 12 km from the Mediterranean Sea and 15 km from the city of Oran, with a size of approximately 44km by 12km (52800 Ha).

The depression starts at 110 meters altitude and finishes at -80 meters below sea level. It is closed and restricted to the north by the massif of Murdjadjo, whose maximum altitude is 589 meters, and to the south by the massif of Tessala, whose maximum altitude is 1061 meters.

Algeria - May 4th, 2011

Coastal Algeria appears green and fertile in comparison to the arid Sahara Desert to the south. Visible across the Mediterranean Sea, in the upper left corner, is a small area of Spain.

Upon opening the full image, the Great Sebkha or Sebkha of Oran can be seen by the coast near the left edge of the image. It is a salt lake in a depression in Algeria distant 12 km from the Mediterranean Sea and 15 km from the city of Oran, with a size of approximately 44km by 12km (52800 Ha).

Here, its color mostly blends in with the surrounding terrain, although its texture does not. A green streak of algae stretches from the center towards the eastern end.

A small section of Algeria’s Mediterranean coastline, near the border with Morocco, is visible in the upper left corner. Slightly inland, a large green lake whose shores are coated with tan sediments, is visible.

Called the Sebkha of Oran, it is a salt lake that covers most of the territory of the Boutlélis District in Algeria’s Oran Province.

Moving farther inland, away from the fertile green coast, another large lake can be observed. This lake, known as Chott Ech Chergui, is a large endorheic salt lake in the Saharan Atlas. It is one of the largest lakes in Algeria, with an area of about 2000 km². This area is designated a Ramsar wetland of international importance.

According to the Ramsar Organisation, it is the second largest chott in North Africa; an extensive closed depression containing permanent and seasonal saline, brackish, and freshwater lakes and pools, as well as hot springs.

The habitats here are diverse, including steppe areas that are always green, the land around the chott and the “sebkhas” which has no vegetation, and acquatic areas with lake and marsh vegetation.

Many threatened and vulnerable plant species are present. The area is also important for several species of migratory waterbirds, which use it as a site for nesting and wintering.

The area is used for agriculture and raising livestock by humans. However, human use also may also cause environmental problems, such as overgrazing, poaching, desertification, and deforestation for firewood.

A dense, bright green color surrounds an outflow of tan sediments that is moving to the west, down the coast of Algeria. The sediments billow out into the Mediterranean Sea just above the Gulf of Arzew.

Continuing west, past the gulf, and moving inland, a large lake can be seen. This is a salt lake called the Sebkha of Oran. It covers most of the territory of the Boutlélis District in Algeria’s Oran Province.

The entire lake appears bright green, and there are tan sediments on the southern and eastern shores.

Moving farther inland, another large lake, called Chott Ech Chergui, can be found. It is a large endorheic salt lake in the Saharan Atlas. With an area of about 2000 km², it is one of the largest lakes in Algeria.

Chott Ech Chergui is designated a Ramsar wetland of international importance. Here, a large part is covered by sediments, and the remainder appears bright green.
