“…Continuous multi-year data of deposition flux have been reported for dusts transported from desert areas such as central and eastern Asia (Inoue and Naruse, 1987;Yabuki et al, 2005;Hsu et al, 2009;Sun et al, 2003;Ta et al, 2004;Zhang et al, 1993), North America (Reheis, 2006), and the Middle East and Sahara (Ganor et al, 2003;Offer and Goossens, 2004;Pye, 1992;Nihlén et al, 1995;Loye-Pilot and Martin, 1996).

Abstract. Recent ground networks and satellite remotesensing observations have provided useful data related to spatial and vertical distributions of mineral dust particles in the atmosphere. However, measurements of temporal variations and spatial distributions of mineral dust deposition fluxes are limited in terms of their duration, location, and processes of deposition. To ascertain temporal variations and spatial distributions of mineral dust deposition using wet and dry processes, weekly deposition samples were obtained at Sapporo, Toyama, Nagoya, Tottori, Fukuoka, and Cape Hedo (Okinawa) in Japan during October 2008-December 2010 using automatic wet and dry separating samplers. Mineral dust weights in water-insoluble residue were estimated from Fe contents measured using an X-ray fluorescence analyser. Wet and dry deposition fluxes of mineral dusts were both high in spring and low in summer, showing similar seasonal variations to frequency of aeolian dust events (Kosa) in Japan. For wet deposition, highest and lowest annual dust fluxes were found at Toyama (9.6 g m −2 yr −1 ) and at Cape Hedo (1.7 g m −2 yr −1 ) as average values in 2009 and 2010. Higher wet deposition fluxes were observed at Toyama and Tottori, where frequent precipitation (> 60 % days per month) was observed during dusty seasons. For dry deposition among Toyama, Tottori, Fukuoka, and Cape Hedo, the highest and lowest annual dust fluxes were found respectively at Fukuoka (5.2 g m −2 yr −1 ) and at Cape Hedo (2.0 g m −2 yr −1 ) as average values in 2009 and 2010. The average ratio of wet and dry deposition fluxes was the highest at Toyama (3.3) and the lowest at Hedo (0.82), showing a larger contribution of the dry process at western sites, probably because of the distance from desert source regions and because of the effectiveness of the wet process in the dusty season.Size distributions of refractory dust particles were obtained using four-stage filtration: > 20, > 10, > 5, and > 1 µm diameter. Weight fractions of the sum of > 20 µ m and 10-20 µm (giant fraction) were higher than 50 % for most of the event samples. Irrespective of the deposition type, the giant dust fractions generally decreased with increasing distance from the source area, suggesting the selective depletion of larger giant particles during atmospheric transport. Based on temporal variations of PM c (2.5 < D < 10 µm), ground-based lidar, backward air trajectories, and vertical profiles of potential temperatures, transport processes of dust particles are discussed for events with high-deposition and low-deposition flux with high PM c . Low dry dust depositions with high PM c concentrations were observed under stronger (5 K km −1

“…"Typical" loess is characterized by higher detSiO 2 /Al 2 O 3 , MgO/Al 2 O 3 , Na 2 O/Al 2 O 3 , and K 2 O/Al 2 O 3 than "weathered" loess, and composition of Kosa is explained as the mixture of "typical" loess and "weathered" loess, which suggests that Kosa is supplied not only by arid Chinese inland area but also by peripheral soil. Leinen et al (1994) showed that mineral (n = 21) are Kosa collected in Japan (Inoue and Naruse, 1987;Kanamori et al, 1991), and "typical" loess (n =14) and "weathered" loess (n = 10) category are after Gong et al (1987) and Inoue and Naruse (1987). The data included in arcderived detritus category (n = 195) are neritic mudstones of the Japan Sea side (Irino, 1992MS;Sakamoto, unpublished data Sakamoto, pers.…”

“…The present Kosa flux to Japan is estimated to be 0.7 to 4.3 g/cm 2 /ky based on atmospheric dust concentration on Japanese Islands assuming that the diameter of Kosa particle is ~6 µm and its deposition velocity is 8 cm/sec (Suzuki and Tsunogai, 1987). Inoue and Naruse (1987) also estimated the Kosa flux as 0.5 to 1.0 g/cm 2 /ky based on the concentration of dust within precipitation in northeastern and southwestern Japan. These estimations are about ten times larger than the flux to the central North Pacific between 30°a nd 40°N (0.1 to 0.2 g/cm 2 /ky) calculated as the mass accumulation rates of total detrital mineral component for core top samples (Hovan et al, 1991;Rea, 1994;Rea et al, 1998), and are comparable to the average total mass accumulation rate of 4.1 g/cm 2 /ky during Quaternary at site 797 (Shipboard Scientific Party, 1990).…”

“…In order to examine the origin of the four detrital subcomponent factors, the chemical compositions embedded in the factors are compared with those of possible source materials such as aeolian dust collected around Japan (Kosa) (Inoue and Naruse, 1987;Kanamori et al, 1991), "typical" loess, "weathered" loess (Gong et al, 1987;Inoue and Naruse, 1987), Miocene to Pliocene neritic mudstone collected from the Northeast Japan which represents fine-grained detritus derived from Japan Arc (Irino, 1992MS, Sakamoto, unpublished data), and various Quaternary tephra deposits in and around Japan (Machida and Arai, 1992).

In order to reconstruct past variations in the aeolian dust (Kosa) contribution to the Japan Sea, and to establish a direct link between terrestrial and marine climatic records, we have applied statistical procedures to distinguish and quantify detrital subcomponents within the detrital fraction of the late Quaternary hemipelagic sediments in the Japan Sea. Q-mode factor analysis with varimax and oblique rotation of the factors followed by multiple-regression analysis between mineral composition and factor loadings was conducted using six "detrital" elements. Four detrital subcomponents were defined, which are attributed to Kosa derived from "typical" loess, Kosa from "weathered" loess, and fine and coarse arc-derived detritus, respectively, based on comparisons with the chemical and mineral compositions of probable source materials. Using these detrital subcomponents, the variation in Kosa fraction was reconstructed for the last 200 ky. The results reveal millennial-scale as well as glacial-interglacial scale variations in Kosa contribution. Especially, millennial-scale variability of Kosa contribution suggests the presence of high frequency variation in summer monsoon precipitation in the central to east Asia during the last 200 ky.

“…Older tephra deposits are generally more acidified and have been exposed to eolian deposition of exogenous materials containing 2:1 layer silicates or their precursors, such as loess from China (Bautista-Tulin and Inoue, 1997;Inoue and Naruse, 1987;Mizota and Inoeu, 1988;Mizota et al, 1990;Saigusa and Matsuyama, 1998). Mixing of alluvial or residual deposits with volcanic materials may also result in formation of non-allophanic Andosols.…”

Andosols (or Andisols) possess several distinctive properties that are rarely found in other groups of soils. These properties are largely due to the dominance of short-range-ordered minerals (allophane, imogolite and ferrihydrite) and/or metal-humus complexes (Al/Fe-humus complexes) in their colloidal fraction. While several papers have extensively reviewed the nature and properties of short-range-ordered minerals, there is no comprehensive review of the genesis, characteristics and management implications of Al-humus complexes, the dominant form of active Al in non-allophanic Andosols. In this review, we survey the chemical characteristics of Al-humus complexes and discuss the pedogenic environment favoring their formation in non-allophanic Andosols. The role of Al-humus complexes in carbon cycling and soil organic carbon accumulation is emphasized as an important mechanism controlling organic dynamics in Andosols. While non-allophanic Andosols share many common properties with allophanic Andosols, they display several distinct characteristics associated with Al-humus complexes, such as strong acidity and high exchangeable Al content that impair agricultural productivity due to Al phytotoxicity. Thus, we focus on the role of Al-humus complexes in regulating aqueous Al 3+ solubility and release/retention kinetics, Al phytotoxicity, phosphorus dynamics, and suppression of soil-borne diseases. Knowledge of these soil properties as related to Al-humus complexes is necessary to develop effective soil management practices to assure sustainable agricultural productivity in non-allophanic Andosols. Finally, future research needs are identified concerning the role of Al-humus complexes in regulating soil biogeochemical processes.
