The sand seas of the Namib and their distribution [Die sandsee van die Namib en hul verbreiding]

Barnard W.S. (1988)

The three sand seas of the Namib Desert, Namibia, occupy 56 600 km2 or 29.4% of the desert's total area of 192 400 km2. Similarities among the three sand seas include zones of barchanoid dunes along the coast in the central and northern sand seas (18.9% of the total sand covered area) and linear dunes in the interior of the southern and central sand seas (45.4% of the total covered area), both features fitting well with the unimodal and bimodal wind regimes of the two respective zones. The southern sand sea includes a coastal zone of deflation-controlled sand forms which is associated with the exceptionally high-energy unimodal winds of the Bogenfels-Luderitz area. The dunes along the eastern border of the central sand sea suggest a long history which goes back the Eocene. -from English summary
