"Proterozoic Climate Investigation: The Methane Trail"

Publié le :

By studying the biogeochemical characteristics of a particular lake located in Mayotte, IRD researchers and their partners reveal that the climatic conditions at the end of the Precambrian may have been modulated by methane, a greenhouse gas of biological origin. Their results are published in the Scientific Reports of the journal Nature.

MARBEC MARine Biodiversity, Exploitation and Conservation, is a research unit which includes the staff of 4 organizations: IRD, IFREMER, UM and CNRS. Its objective is the study of marine biodiversity in lagoon coastal and offshore ecosystems, at different integration levels, molecular, individual, population and community aspects and the way humans use this biodiversity.
