The efficiency of 5 aeolian sand samplers was tested via wind tunnel experiments and field measurements : the Big Spring Number Eight (BSNE) sampler, the Modified Wilson and Cooke (MWAC) sampler, the Suspended Sediment Trap (SUSTRA), the Pollet

The AA. examine the aeolian dynamics of sand and dust during a wind erosion event on loamy sandy soil in Northern Germany. The large percentage of dust (up to 32%) in the topsoil and the high frequency of wind erosion events make the region suitable
for studying the behaviour of both components simultaneously. The aim is to check whether differences exist in the patterns of erosion, transportation, deposition and accumulation (deposition minus erosion) during a single wind erosion event.

The effect of rock fragment cover on the deposition of airborne dust was examined in a wind tunnel. Four parameters were studied: pebble size, pebble flattening, cover density and wind speed. The effect of these parameters on the deposition of dust

The dynamics of fine aeolian dust emitted from agricultural land was investigated over 15 months near Grönheim, Lower Saxony. This study was unsertaken in the framework of WEELS (Wind Erosion on European Light Soils), an international EU project
focusing on wind erosion in northern Europe. Dust activity in Grönheim is high in spring and autumn, and low to very low during the rest of the year. There is a strong relationship between the periods of tillage and the intensity of dust activity.
