“…This view stems from a period of considerable research and controversy that culminated some 40 years ago. During this period a number of authors presented work indicating that many or all of these inorganic elements were significantly enriched in sea spray aerosol particles compared to seawater [Sugawara et al, 1949;Komabayasi, 1962]. However, a comprehensive review discussing these studies attributed observations of significant fractionation during sea spray aerosol particle production to poor experimental techniques and failure to exclude non-sea-spray aerosol particles, e.g., mineral dust, from measurements [Duce and Hoffman, 1976].…”

Sea spray aerosol particles are an integral part of the Earth's radiation budget. To date, the inorganic composition of nascent sea spray aerosol particles has widely been assumed to be equivalent to the inorganic composition of seawater. Here we challenge this assumption using a laboratory sea spray chamber containing both natural and artificial seawater, as well as with ambient aerosol samples collected over the central Arctic Ocean during summer. We observe significant enrichment of calcium in submicrometer (<1 μm in diameter) sea spray aerosol particles when particles are generated from both seawater sources in the laboratory as well as in the ambient aerosols samples. We also observe a tendency for increasing calcium enrichment with decreasing particle size. Our results suggest that calcium enrichment in sea spray aerosol particles may be environmentally significant with implications for our understanding of sea spray aerosol, its impact on Earth's climate, as well as the chemistry of the marine atmosphere.

“…In most of the rainwater samples the E value for calcium is considerably higher than unity. Sugawara et al [1949] and Koyama and Sugawara [1953] suggested that the bursting bubbles at the sea surface result in a strong fractionation of elements, but this hypothesis has not been experimentally sustained . Thus most of the calcium in rainwater should originate from nonmarine origins, such as soils, fertilizers, or industrial wastes.…”

Calcite as a source of excess calcium in rainwater

Snow and rain samples collected in Sendai, Japan, were analyzed for sodium, potassium, magnesium, calcium, and strontium. The chemical composition of the samples can be fairly explained by adding some calcium to diluted seawater. A low Sr/Ca ratio in most of the samples showed that the excess calcium over seawater contribution may be derived from calcite contained in soil dust transported by wind from North China.
