Many scattered accounts have appeared concerning the dust which has fallen in considerable quantities on vessels on the African side of the Atlantic Ocean. It has appeared to me desirable to collect these accounts, more especially since Professor Ehrenberg's remarkable discovery that the dust consists in considerable part of Infusoria and Phytolitharia. I have found fifteen distinct statements of dust having fallen; and several of these refer to a period of more than one day, and some to a… Expand
Airborne dust collected at Barbados
Abstract Wind-borne dust collections have been made on the island of Barbados; and the day by day amounts have been recorded for several months, commencing August 1965. From mineralogical andExpand
Influence of Saharan dust on the rain acidity and atmospheric input to the Mediterranean
It has long been recognized that Saharan dust may be transported a long way from its sources, particularly over the ocean1, and especially over the tropical North Atlantic, as far as theExpand
Airborne dust and its significance to soils
Abstract Movement of mineral dust by the atmosphere has been underway for ages, but efforts to assess its magnitude and significance have come largely in the last century. Attempts to identify andExpand
Mineral-Aerosol Transport to the North Atlantic and North Pacific: The Impact of African and Asian Sources
In many respects, mineral dust is one of the oldest and longest studied examples of long-range transport. The earliest accounts of this phenomenon, many of which appeared in the general press, areExpand
Atmospheric transport of soil dust from Africa to South America
The arid and desert regions of North Africa are a prolific source of atmospheric dust. This dust is, for example, responsible for the ‘red snows’ reported in the Alps and Pyrenees1 and for dust fallsExpand
The nature and early history of airborne dust from North Africa; in particular the Lake Chad basin [rapid communication]
Abstract Africa is the great source of airborne dust, and a very large proportion of it blows out of the Lake Chad basin. There are various types of dust, an initial simple division might be intoExpand
Rates of sedimentation on the Cape Verde Rise
Abstract The hypothesis that the Cape Verde Rise, situated on the lee-side of the Canaries current and being an area of low current velocities, would be a sediment trap, was tested by determiningExpand
On the variability of African dust transport across the Atlantic
[1] We investigate the interannual variability of Saharan dust transport over the Atlantic by using the TOMS/Nimbus-7 and TOMS/Earth Probe daily aerosol data. We focus on the winter season, and onExpand
Airborne dust transport to the eastern Pacific Ocean off southern California: Evidence from San Clemente Island
[1] Islands are natural dust traps, and San Clemente Island, California, is a good example. Soils on marine terraces cut into Miocene andesite on this island are clay-rich Vertisols or Alfisols withExpand
Saharan aerosols over the tropical North Atlantic — Mineralogy
Abstract Quantitative aerosol samples were collected on filters during three major Saharan dust outbreaks as they passed across the tropical North Atlantic Ocean during the summer of 1974. TheExpand
