Islands but a significantly lower concentration between the Galapagos and Tahiti. In the clean marine atmosphere, several concentration ratios were significantly different from those in bulk seawater; 'departures from seawater composition were significantly larger in the Pacific' than in the Atlantic--attributed to 'differences in sea-to-air fractionation processes.'

Res., 88(C9): 5321-5342. Lower-atmosphere aerosol particles collected during SEAREX were analyzed for trace element concentrations; Asian dust storms, crustal weathering and the marine realm were the dominant element sources. Based on the controlling sources of input, the 29 elements examined fell into 4 groups. Grad. Sch. of Oceanogr., Univ. of Rhode Island, Kingston, RI 02881, USA. (ihz) 83:6671 Lee, In-Young, 1983.

Transport of mineral aerosol from Asia over the North Pacific Ocean. J. geophys. Res., 88(C9):
5343-5352. SEAREX Asian Dust Network measurements showed a seasonal transport pattern at most sites, with high concentrations from February to June and low concentrations from July to January. A latitudinal gradient in the mean annual atmospheric dust concentration peaked in the mid-latitudes. It is estimated that 6-12 × 106 tons of Asian dust are transported annually by the westerlies from arid regions in Asia to the central North Pacific; larger quantities are probably deposited over the western North Pacific. This mineral aerosol is a significant source of North Pacific sedimentary material. Grad. Sch. of Oceanogr., Univ. of Rhode Island, Kingston, R.I. 02881, USA.

Mar. Chem., 13(1):57-72. An analysis of 111 filter-collected atmospheric particulate samples shows that Pb distribution in both hemispheres is controlled by mixing of a background component(s) with crustal material. Northern Hemisphere samples have a 'reasonably well-defined' Pb concentration minimum of 0.6 ng/m 3 of air. Average Pb concentrations range from ~0.98 ng/m 3 in the South Atlantic westerlies to ~ 15 ng/m 3 in the North Atlantic westerlies. Deposited over the North Atlantic are ~<24% of the total 'natural' Pb injected into the global atmosphere and ~<3.5% of the anthropogenic Pb injected into the Northern Hemisphere.
