Sea bed provides information about present climatic change
Date:1/22/2009

This release is available in Spanish.

Lately, every drought, flood or hurricane which happens in the planet is connected with climatic change, and therefore the interest of society and scientists is getting to know this phenomenon better.

Climatic change is connected at present with the phenomenon of global warming. This is characterized by the increase of carbon dioxide (CO2 gas), which produces the reduction of heat emission to the space and provokes a higher global warming.

Although gases in the atmosphere tell us about this greenhouse effect, oceans have accumulated information for million years which allow us a better understanding of this phenomenon.

The past lets us know the present

In this process, which involves a better knowledge of carbon cycle in the sea, David Gallego Torres developed the research work "Acumulacin y preservacin de materia orgnica en sedimentos marinos: implicaciones en los ciclos del carbono y nutrientes" (Accumulation and preservation of organic matter in marine sediments: implications in the cycles of carbon and nutrients), under the supervision of Professors Francisca Martnez Ruiz and Miguel Ortega Huertas of the University of Granada (Andalusian Institute of Earth Sciences, CEAMA and Department of Mineralogy and Petrology).

"Oceans may act as a drain of carbon, in the way of inorganic carbonates or as organic matter settled in sediments", says Gallego Torres, who did research, among other phenomena, into the accumulation of organic matter in the geological past (Plioceno-Holoceno), in the East of the Mediterranean.

According to the researcher, "for the carrying out of this work we
