It has long been conjectured that spray ejected from the high-wind ocean surface enhances air/sea enthalpy fluxes, but a lack of observational data, particularly at wind speeds exceeding 20 m s−1, has prevented either confirmation or refutation of this hypothesis. The current study has two aims: first, to provide an estimate of surface enthalpy fluxes obtained from dropsonde data and second, to...

The main goal of the proposed research is to study theoretically the role of the breaking wind waves and the sea spray, generated by them, under strongly forced situations in the airflow dynamics in particular in energy, momentum, heat and moisture transfers through the sea surface. Through this to increase the knowledge of the air-sea interaction and to apply this knowledge for developing impr...

Introduction Conclusions References

Sea spray aerosol (SSA) particles provide the connection between the ocean and the atmosphere with a profound and not yet fully understood impact on climate; in this issue, in related papers, teams lead by Kimberly Prather and Timothy Bertram have completed studies that together shed light on important factors in SSA composition and properties. What has been known is that aerosols scatter solar...

Introduction Conclusions References

The intentional enhancement of cloud albedo via controlled sea-spray injection from ships (marine cloud brightening) has been proposed as a possible method to control anthropogenic global warming; however, there remains significant uncertainty in the efficacy of this method due to, amongst other factors, uncertainties in aerosol and cloud microphysics. A major assumption used in recent cloudand...

Biogenic influences on the composition and characteristics of aerosol were investigated on Bird Island (5400 S, 3803 W) in the South Atlantic during November and December 2010. This remote marine environment is characterised by large seabird and seal colonies. The chemical composition of the submicron particles, measured by an aerosol mass spectrometer (AMS), was 21 % non-sea-salt sulfate, 2 % ...

The goal of this project is to develop a new capability for the chemical characterization of marine aerosols. This involves the development of an instrument to make quantitative, near real-time sodium concentration measurements on individual size-segregated marine aerosols. The development and deployment of a single particle sodium detector would allow us to measure the size distribution of sea...
