Eolian transport

Witherow et al., 2006). Eolian transport of local soils and lake sediments is a documented dispersal mechanism for valley floor life as well as life immured in glacier ice and cryoconite holes (Christener et al., 2003 Nkem et al.,...

Eolian transport Delivery of fine particles (pollen, soot, dust) by winds, often from distantlocations. 

These dates confirm that the age of the diatoms in the ClROS-2 core is abont 3.0 Ma which is the time when the East Antarctic ice sheet may have melted allowing seawater to flood the Pensacola Basin on the East Antarctic craton. However, the eolian transport of diatoms advocated by Kellogg et al. (1997) means that the presence of marine diatoms in glacial deposits no longer requires the conclusion that the East Antarctic... 

A survey of available Th data for the ocean basins demonstrated that the highest concentrations are found nearer to the coasts, and it was concluded that while eolian inputs likely dominated the budget in the open ocean and could account for increases near the coast, fluvial inputs may be more important in coastal regions. This implies that some a mechanism causes recycling of Th that has been removed to estuarine sediments (Huh et al. 1989). A study of an ice-covered region of the western Arctic Ocean found that significant amounts of °Th and Th were advected into the basin (Edmonds et al. 1998). Therefore, it appears that while long-lived Th isotopes are rapidly removed into estuarine sediments, transport into the ocean basins may continue. 

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. 

Eolian Describes materials that have been transported by wind or landforms that are created by wind. 

In each case, changes in the elemental ratios are caused by relative changes in bulk sedimentation— dilution or condensation results from changes in the terrigenous clay flux relative to eolian or other inputs. Correct interpretation of proxies depends on distinguishing elemental sources and transport... 

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 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.

The primary gaseous carrier for transport of C from the low-level radioactive-waste disposal site (lat. 41 20 N, long. 89 47 W), near Sheffield, Bureau County, Illinois is C02 (1). Production of the gas is caused by aerobic microbial decomposition of organic waste buried in waste-disposal trenches. This results in steep gradients in P C02 in undisturbed glacial and eolian sediments adjacent to the site. To collect samples of unsaturated zone gases, nests of gas piezometers were installed along a cross section in boreholes located at distances of 12,29, and 46 m from the end wall... 

The distribution of kaolinite in marine sediments (Fig. 1.15) depends on the intensity of chemical weathering at the site of the rock s origin and the essential patterns of eolian and fluvial transport. Due to its concentration at equatorial and tropical latitudes, kaolinite is usually referred... 

The fluvial input of dissolved and suspended material to the ocean presents a boundary condition, which can reliably be estimated (cf. Fig. 1.2). Apart from eolian particle transport, which may be of great importance in areas adjacent to the great desert regions, this mode of transport represents the major pathway of element... 

Eolian a term applied to the erosive action of the wind and to deposits which are the result of the transporting action of the wind.
