...Kana Nagashima; Hirotsugu Nishido; Masahiro Kayama; Yasunori Kurosaki; Syuhei Ohgo; Hitoshi Hasegawa Abstract Although dust from the Asian drylands significantly affects global climate, the provenance of dust transported over a long distance is often uncertain. In this study, we developed a new...

... variations in the terrigenous dust input in this pelagic, deep-marine environment. We speculate that the dust is mainly eolian in origin and that the availability and transport of dust are influenced by variations in the vegetation cover on the Maastrichtian-Paleocene African or Asian zone, which were...

... of the particulate matter in the degradation of architectural ceramics. For this reason the attic dust and settled dust from the roofs of the studied buildings were collected. In the attic dust, besides the natural particles of geological origin, three types of artificial particles typically with spherical shape...

... After the high-radiation environment and the low gravity field on Mars, dust is arguably the next biggest environmental hazard facing a manned mission to Mars. The seriousness of this threat is still being studied with robotic missions. At its most benign, Martian dust the work undertaken were...

.... These were located in the Sahelian zone of Niger with an average annual rainfall of 560 mm. The vertical upward fluxes of particles <20 mu m exported from the study area were estimated from the horizontal sediment fluxes measured using BSNE sand catchers. This mass of exported dust was compared...

Elevated values in microparticle number and mass, especially during the Younger Dryas, are related to Northern Hemisphere aridity and the subsequent increase in dust available for long-range transport to Greenland. This scenario occurs with the colder climatic conditions that result from a more...
