Ocean Microbes can alter Earth’s Atmosphere

A novel research has unveiled that ocean microbes have a major impact on atmosphere. The finding could bring changes in how climate models are developed and interpreted, bringing changes in entire concept of climate change.

The novel study has also unveiled that cool mist also plays an important role in the environment. Not only the cool, but warm mist also alters how sunlight is reflected and bounces off from water surface, an important part of cloud formation.

Researchers from the Center for Aerosol Impacts on Climate and the Environment (CAICE) said that when microorganisms decay, bacteria break them and in this process, chemicals and proteins are released with sugar and lipids.

These materials are then emitted into atmosphere with ocean mist. The researchers conducted an experiment in which they created a simulation of the above mentioned process. In the experiment, a photoplankton bloom was produced in a laboratory using a wave machine having 3,400 gallons of water taken from the coast of California.

After conducting the experiment, the researchers noticed that the microbes in water can bring modify the chemicals of the mist transferred into air. The researchers said that it was especially more evident when lipids were examined.

Sea spray aerosol (SSA) particles were found to be carrying lipids in abundance when they were carried through bubbles. The researchers affirmed that these chemicals have significant influence on the environment.

“Freshly emitted SSA are composed of both sea salt and organic material, and under certain conditions the organic species comprise a substantial fraction of the total particle mass, especially for smaller diameter particles”, affirmed researchers.

More than 70% of the planet’s surface is covered with the world’s oceans. The microbes can alter how oceans respond to climate change. They can also help better understand of how increasing level of greenhouse gases affect the relationship of the ocean with the atmosphere.
