“…Because Na1 is known to form primary particles from evaporating seawater droplets, the close correlation of organic components with Na1 suggests their direct association and probable primary formation. Positive correlations of Na with fatty acids within aerosol particles were found by Pelzer et al (24) and Mochida et al (15) for pristine regions. In addition, Crahan et al (10) found a correlation between carbohydrates and Na concentration for particles of marine origin in the Northeastern Pacific.…”

“…The most striking feature of the ICEALOT organic functional group composition with respect to measurements in other regions (22)(23)(24) is the abundance of organic hydroxyl functional group mass during the ICEALOTcampaign, accounting for 47% of OM1 on average (see Table S1). This feature is more pronounced in the North Atlantic and Arctic air masses that had some of the lowest OM1 and PM1 concentrations but the highest fractions of organic hydroxyl groups compared to other coastal or open ocean campaigns, as shown in the pie charts in Fig.…”

Oceans cover over two-thirds of the Earth's surface, and the particles emitted to the atmosphere by waves breaking on sea surfaces provide an important contribution to the planetary albedo. During the International Chemistry Experiment in the Arctic LOwer Troposphere (ICEALOT) cruise on the R/V Knorr in March and April of 2008, organic mass accounted for 15-47% of the submicron particle mass in the air masses sampled over the North Atlantic and Arctic Oceans. A majority of this organic component (0.1 − 0.4 μ m −3 ) consisted of organic hydroxyl (including polyol and other alcohol) groups characteristic of saccharides, similar to biogenic carbohydrates found in seawater. The large fraction of organic hydroxyl groups measured during ICEALOT in submicron atmospheric aerosol exceeded those measured in most previous campaigns but were similar to particles in marine air masses in the open ocean (Southeast Pacific Ocean) and coastal sites at northern Alaska (Barrow) and northeastern North America (Appledore Island and Chebogue Point). The ocean-derived organic hydroxyl mass concentration during ICEALOT correlated strongly to submicron Na concentration and wind speed. The observed submicron particle ratios of marine organic mass to Na were enriched by factors of ∼10 2 -∼10 3 over reported sea surface organic to Na ratios, suggesting that the surface-controlled process of film bursting is influenced by the dissolved organic components present in the sea surface microlayer. Both marine organic components and Na increased with increasing number mean diameter of the accumulation mode, suggesting a possible link between organic components in the ocean surface and aerosol-cloud interactions.atmospheric aerosol | marine carbohydrates | organic aerosols | sea salt particles

“…Aerosols were collected on a pre-extracted Gelman type A/E glass fiber filter from a tower (20 m) erected on the beach or cliff of each island (Peltzer et al, 1984). The air sampler was automatically operated only when the wind came from the ocean to prevent contam- ination from local sources.…”

In remote marine aerosol samples collected from the North Pacific ocean, Enewetak Atoll, American Samoa, and New Zealand, series of mid-chain ketocarboxylic acids in the range of C 6-C1s were detected. All the positional isomers, except for the 2-oxo and 3-oxo species, were detected for major ketoaeid families (e.g. C 9 , C H and C13 ). Higher ketoacid concentrations (up to 19 ng/m 3 ) were obtained in the northern North Pacific aerosol samples, which generally showed an odd carbon-numbered predominance with 5-oxoundecanoic acid being the major species. By contrast, lower concentrations were obtained in the lower-latitude or subtropical aerosol samples, where even carbon-numbered ketoacids were relatively abundant.The distribution patterns of the odd carbon-numbered ketoacids could not be explained by the primary emissions from source materials including terrestrial higher plants, soil particles, and ocean surfaces. We consider that the isomeric ketoearboxylic acids are produced in the atmosphere by the photochemical oxidation of semi-volatile monocarboxylic acids, which are counterparts of the oxidative degradation of unsaturated fatty acids emitted from seawater surfaces. Atmospheric production of the ketoacids is seemingly enhanced in the northern North Pacific, probably due to an enhanced primary productivity.
