Eolian dust transport

The share of eolian dust transport in continental erosion is submerged in the greater range of uncertainties associated with the transport rates, as discussed in the preceding paragraphs. 

It must be stressed that although the trend observed in the coastal zone of the Ross Sea was not so marked and regular as the results of Saager et al., the effect of local phenomena can be assumed. In fact, glacier transport and the ice pack formation/dissolution cycle can play a fundamental role in the composition of surface coastal sea water. However, more detailed information about the local sources (eolian dust composition and deposition rate, glacier composition and dissolution rate, effect of pack ice dissolution and formation) are necessary to establish the origin of the surface water enrichment.

The finest particles composed of fine silt and clay are carried over much larger distances (Fig. 1.6). Using oxygen isotopes of aeolian quartz, it has been shown that significant quantities of dust with an average diameter of 1-10 microns are transported by jet streams from desert zones over the rest of the world. Eolian admixtures have been referred to explain the presence of Si02 in soils developed in non-quartz-containing volcanic rocks in Hawaii and Israel.
