The objective of this blog is to post images and news, that are published at other websites, that are concerned about the conditions of our the world oceans. It is also an english version SOS OCEANOS.We also write and publish relevant information and photographs of our region whenever is necessary people to know.

BBC E-mail: Acid oceans 'need urgent action'
Trajano Paiva saw this story on the BBC News website and thought you should see it.
** Acid oceans 'need urgent action' **
Marine ecosystems risk being severely damaged by ocean acidification unless there are dramatic cuts in CO2 levels, warn scientists.

about Ocean Acidification processes

About Ocean Acidification
The ocean absorbs approximately one-fourth of the CO2 added to the atmosphere from human activities each year, greatly reducing the impact of this greenhouse gas on climate. When CO2 dissolves in seawater, carbonic acid is formed. This phenomenon, called ocean acidification, is decreasing the ability of many marine organisms to build their shells and skeletal structure. Field studies suggest that impacts of acidification on some major marine calcifiers may already be detectable, and naturally high-CO2 marine environments exhibit major shifts in marine ecosystems following trends expected from laboratory experiments. Yet the full impact of ocean acidification and how these impacts may propogate through marine ecosystems and affect fisheries remains largely unknown.
