The outstanding combination and characteristics of the physical environment — loose sand, variable winds and fog gradients across the property — creates an ever-changing variety of micro-habitats and ecological niches that is globally unique on such a scale.

The property is of outstanding importance for the in-situ conservation of an unusual and exceptional array of endemic species uniquely adapted to life in a hyper-arid desert environment in which fog serves as the primary source of water. Integrity The boundaries of the property encompass all the elements of the Namib Sand Sea that exemplify its Outstanding Universal Values.

These elements are well conserved and included at a scale appropriate to maintaining ongoing dynamic processes. The large size of the area 30, km2 ensures that all the active and underlying fossilized dune formations and features, causative processes and ancillary habitats are included.

The extensive dune-scapes are unspoilt and continuously refreshed and maintained by wholly natural processes. Because of its vast size, difficulty of access and current management within the protected Namib-Naukluft Park 49, km2the Namib Sand Sea is well conserved and in an excellent, undamaged state.

Permanent visitor and management infrastructure is non-existent within the boundaries of the property and visitation is restricted to small, temporary point locations that have no measurable effect on the area. Aerial photo of Kuiseb RiverMay 14th Namib sand sea to the left.

This research focuses on one of the better studied of these terrace sequences, the Homeb Silts in the Kuiseb Canyon, Namibia Fig. The Kuiseb River 15, km2 runs along the northern boundary of the hyper-arid Namib Desert. Twenty-five meter thick sequences of sand, silt and clay are preserved in channel and tributary mouth embayments and now stand up to 45 m above the channel bed Fig. These remarkable deposits have a well preserved stratigraphy and their facies are typical of slackwater environments.

Several depositional models have been proposed, including lacustrine and fluvial. This is due to several factors. Winds coming from the Indian Ocean lose part of their humidity when passing the Drakensberg mountains, and are essentially dry when they reach the Namib Escarpment at the eastern end of the desert.

Winds coming from the Atlantic Ocean, on the other hand, are pressed down by hot air from the east; their humidity thus forms clouds and fog. Morning fogs coming from the ocean and pushing inwards into the desert are a regular phenomenon along the coast, and much of the life cycle of animals and plants in the Namib relies on these fogs as the main source of water.

The dry climate of the Namib reflects the almost complete lack of bodies of water on the surface. The Swakop and the Omaruru are the only rivers that occasionally drain into the ocean.

All along the coast, but mostly in the northernmost part of it, interaction between the water-laden air coming from the sea via southerly windssome of the strongest of any coastal desert, and the dry air of the desert causes immense fogs and strong currents.

It causes sailors to lose their way; this is testified by the remnants of a number of shipwrecks that can be found along the Skeleton Coastin northern Namib. Some of these wrecked ships can be found as much as 50 metres 55 yards inland, as the desert slowly moves westwards into the sea, reclaiming land over a period of many years.

Warm waters with depth and associated water flows from the northwest were first fully catalogued by Sea Fisheries researchers, Cape Town L V Shannon et al.

Rainfall records also show positive values variously across the Namib, Desert Research Station, Gobabeb for instance.

This event recurs approximately mid-decade,and are recent examples Animals and plants[ edit ] A number of unusual species of plants and animals are found in this desert, many of which are endemic and highly adapted to the specific climate of the area. One of the most well-known endemic plants of the Namib is the bizarre Welwitschia mirabilis; a shrub-like plant, it grows two long strap-shaped leaves continuously throughout its lifetime.

These leaves may be several meters long, gnarled and twisted from the desert winds. The taproot of the plant develops into a flat, concave disc in age.
