Single particle analysis of suspended matter in the Makasar Strait and Flores Sea with particular reference to tin-bearing particles

Variability of Indonesian Throughflow and Borneo Runoff During the Last 14 kyr

“…Core SO217‐18517 was retrieved with a Split‐Piston Corer during the SO217 Makassar‐Java (MAJA) Cruise aboard R/V Sonne in July–August 2011 (Kuhnt et al, ). The coring position was located at 1°32.198′S, 117°33.756′E in 698 m water depth, offshore the southeast distributary of the Mahakam River Delta, which discharges large amounts of terrigenous sediment into the Makassar Strait (Dekov et al, ; Eisma et al, ; Saller et al, ; Storms et al, ). The coring site was chosen on a topographic high to reduce the likelihood of turbidite deposition (Kuhnt et al, ).…”

“…Winnowing of fine‐grained particles occurs seasonally and during periods of enhanced ITF such as during strong La Niña events. Significantly higher flow speeds in the upper thermocline (up to 0.6 m/s annual average and seasonal maxima of 0.9 m/s (Gordon et al, ) additionally promote lateral advection of clay particles from more northerly sources into the central and southern part of the Makassar Strait (Dekov et al, ; Eisma et al, ). Thus, the terrigenous particles accumulating at Site SO217‐18517 may also include suspended material from northern Borneo rivers with catchment areas in different climatic and geologic regions (Aldrian & Susanto, ; Hall & Nichols, ).…”

“…High concentrations of suspended sediment, in the range >2 mg/dm 3 , occur off the Mahakam River mouth (Dekov et al, ; Eisma et al, ). The high terrigenous input from the Mahakam River plume maintains a relatively low carbonate content in sediments around the Mahakam River outflow in contrast to other locations in the Makassar Strait and Flores Sea, which are not affected by the high terrigenous flux from eastern Borneo (Dekov et al, ).…”

Identification of origin of single aerosol particles using polycapillary X-ray lens

“…It can provide more detailed and reliable information of aerosol particles than bulk analysis. The main methods of the analysis of single aerosol particles are electron probe X-ray microanalysis (EPXMA), laser mass microanalysis (LAMMA), micro synchrotron X-ray fluorescence (Micro-SXRF) and micro proton-induced X-ray emission (Micro-PIXE) [1][2][3][4][5]. The MDLs of the EPXMA and LAMMA are higher than those of the Micro-SXRF and Micro-PIXE.…”

Source apportionment of aerosol particles using polycapillary slightly focusing X-ray lens

“…It can provide more detailed and reliable information about aerosol particles, which would be impossible to obtain from bulk analysis. The main single aerosol particle analysis methods are electron probe X-ray microanalysis (EPXMA), laser mass microanalysis (LAMMA), microsynchrotron X-ray fluorescence (Micro-SXRF) and microproton-induced X-ray emission (Micro-PIXE) [1][2][3][4][5]. The detection limit of EPXMA and LAMMA is higher than that of Micro-SXRF and Micro-PIXE.…”
