Abstract

We report the influence of soil dust on marine aerosols inferred from the analysis of aerosol samples collected on board research vessel ‘Gaveshani’ for a period of 11 days during May 1983 over the sea areas around the Indian subcontinent. The number distribution curve over the Arabian Sea was disturbed due to the presence of soil particles in the large size aerosols (r ⩾ 1 μm) as compared to that over the Bay of Bengal. The atmospheric concentration of non sea-salt calcium was positively correlated with the concentration of Fe. The Ca/Na ratios varied widely from the Arabian Sea to the Bay of Bengal with respect to ratio in sea-water. All the excess calcium in the marine aerosols is found to originate from the soil particles of the Arabian Desert and is transported towards the west coast of India
