Sentences with phrase «sea spray aerosol»

According to Prather, the studies have given researchers a newfound understanding of the significance of the complicated relationships between the microbes that can be found in seawater and their impact in the composition and the ability to form clouds of sea spray aerosol.

The study researches the effects of microbial control on sea spray aerosol, along with the blooms included within, in an isolated facility that simulates the atmosphere of the ocean with 3,400 gallons of seawater.

The seawater contains phytoplankton, which is the foundation of the food chain in the ocean and the catalyst that begins the process of how sea spray aerosol particles can change global climate.

Sea spray aerosol (SSA) particles were found to carry lipids in greater concentrations when they were carried in bubbles, which burst through the liquid.

The composition of sea spray aerosol particles are influenced by both chlorophyll - a concentrations and microbial degradation.

«Once the ocean - atmosphere system was isolated, we could systematically probe how changes in the seawater due to biological activity affect the composition and climate properties of the sea spray aerosol,» said Prather, a professor in the Department of Chemistry and Biochemistry who holds a joint appointment at Scripps Institution of Oceanography.

«We suspect that water bound within sea salt, known as hydrates, play a significant role in defining the hygroscopicity of inorganic sea spray aerosol, If true, it means that the particles would take up less water because of the water already present as hydrates and, as a result, they would grow less.

This finding has implications for the role of sea spray aerosols in climate, especially on how they interact with solar radiation,» says Paul Zieger, assistant professor at ACES and co-author of the study.

Sea spray aerosols come in a wide variety of sizes and shapes with chemical complexity ranging from simple salts to complex biological mixtures to bacterial cells.

«But on a larger scale, they constitute sea spray aerosols or sea mist, which plays a huge role in the chemical exchanges between ocean and atmosphere.»

Not exact matches

Exactly how much natural aerosols from volcanoes and sea spray cool the climate remains an elusive question

Sea spray droplets are aerosol water particles that are ejected into the atmosphere as waves break at the ocean surface.

«This paper is indeed universal, and the conclusions can apply to the sea spray produced in oceans or the aerosols produced above a glass of sparkling wine.»

While a large amount of aerosols that exist in the Earth's atmosphere are naturally occurring — created by processes such as mechanical suspension by wind or sea spray — much is produced as a result of industrialization.

The tiny aerosol particles can originate from e.g. dust, pollen or sea spray, emitted straight into the atmosphere or they can be formed from precursor gases.

Natural aerosols come from forest fires, mineral dust kicked up by sandstorms, sea spray and volcanic eruptions, among other things.

The exchange of gases and the emission of sea - spray aerosols — two functions that are crucial for climate — take place in this boundary film.

Additionally, stimulated bacterial degradation might heavily affect the organic composition of nascent sea - spray particles, upon which relies the ability of marine aerosols to interact with the climate system.

These changes might influence interactions between the ocean and the atmosphere such as the air - sea gas exchange and the emission of sea - spray aerosols that can scatter solar radiation or contribute to the formation of clouds.

(In parts of Africa, Asia and the Middle East, aerosols or their precursors come mainly from desert dust, sea spray or wildfires.)

Warming in the tropics and the southern hemisphere has been quite steady, even though there are plenty of aerosols there (although they are different, the major sources in the SH being sea spray and in the tropics sand from the Sahara as well as agricultural burning in Brazil and Africa.

The suggestion of spraying sea salt particles into the air is an example of adding primary aerosol particles to the atmosphere.
