During the study, which is the first of its kind in the Middle East, members from Nasa (National Aeronautics and Space Administration) and the Arab Youth Venture Foundation (AYVF) will research the surface transitions and microbial life from the sandy dunes and desert pavement (gravel surfaces) in areas of Al Ain and Al Gharbia (the Western Region).
The team of scientists will research the surface transitions and microbial life from the sandy dunes and desert pavement (gravel surfaces) in areas of Al Ain and Al Gharbia in the Western Region.
While in UAE, the research team plans to study the surface transitions and microbial life from the sandy dunes and desert pavement
(gravel surfaces) in areas of Al Ain and Al Gharbia.
According to a report in Live Science, the patch of ground is an expanse of "desert pavement
" in Israel's Negev Desert, and is claimed by scientists as the oldest continuous surface on earth.
Embedded in the sun-darkened crust called desert pavement
, the lines are practically invisible until Ramirez begins to describe them.
As the battalions maneuvered across the arid terrain, their vehicles often broke through a delicate crust known as desert pavement. This type of veneer covers as much as half of the world's arid lands.
Damage can happen in a moment, out me processes that sculpt desert pavement typically act slowly, taking centuries to generate a surface resistant to wind erosion.
On weathering, the silcrete forms a desert pavement known as "billy gibbers."
This layer is known as a desert pavement and by other different names in different deserts.
On the E side of the Jornada, five sites were on the W-facing mid-piedmont slope of the San Andres mountain range approximately 50 km NE of Las Cruces, New Mexico, and one site was on the W-facing piedmont slope of the Organ Mountain Range 5 km E of Las Cruces; (7) a loamy-sand alluvial fan ridge that was plowed in 1972 and in 1973 (C-RIDGE-RP), and (8) an adjacent ephemeral stream that was plowed at the same time (C-WASH-RP); (9) a ridge (C-RIDGE) that was not plowed (approximately 0.5 km N of C-RIDGE-RP), and (10) the banks and islands of the adjacent ephemeral stream bed (C-WASH); (11) a site heavily eroded by overland water-flow (C-EROD), on the lower piedmont slope of the San Andres range, and (12) a desert pavement
site (C-PAVE) on the lower alluvial piedmont of the Organ Mountains.
They were created between 400 BC and AD 650 by the removal of reddish oxidised stones from the desert pavement
to reveal the lighter sand beneath.
In these terms, the irreversible transformation of arid ecosystems into anthropic deserts is well documented in many of the world's arid areas, and shown by the cities buried under sand dunes along the Old Silk Road in northwestern China, the steppe grasslands in northern Africa that have become desert pavements
, and the new dune fields in former croplands in the Sahel.
