Koren, Ilan, Kaufman, Yoram J, Washington, Richard, Todd, Martin C, Rudich, Yinon, Martins, J Vanderlei and Rosenfeld, Daniel (2006) The Bodélé depression-a single spot in the Sahara that provides most of the mineral dust to the Amazon forest. Environmental Research Letters, 1 (1). pp. 1-5. ISSN 17489326Full text not available from this repository.
About 40 million tons of dust are transported annually from the Sahara to the Amazon basin. Saharan dust has been proposed to be the main mineral source that fertilizes the Amazon basin, generating a dependence of the health and productivity of the rain forest on dust supply from the Sahara. Here we show that about half of the annual dust supply to the Amazon basin is emitted from a single source: the Bodélé depression located northeast of Lake Chad, approximately 0.5% of the size of the Amazon or 0.2% of the Sahara. Placed in a narrow path between two mountain chains that direct and accelerate the surface winds over the depression, the Bodélé emits dust on 40% of the winter days, averaging more than 0.7 million tons of dust per day
