UGA Study Presents Amazon River Effect on Global Carbon

22 July 2014

According to the scientists at the University of Georgia, a new study reveals a detailed account of microbial activity in the Amazon River as part of a project to comprehend the current global carbon budget and possible future impacts on the ocean. "Microspatial gene expression patterns in the Amazon River Plume" got published on July 14 of the National Academy of Sciences online edition.

Mary Ann Moran, a Research Professor of Marine Sciences at UGA, says, “by collecting data from genes and gene transcripts in the water samples, taking billions of sequences of DNA and RNA from organisms in various places of the plume.” The researchers were able to create a detailed look about the microbial processes found in a drop of seawater. UGA researchers from the departments of Marine Sciences and Microbiology took samples about 300 miles off shore from the mouth of the Amazon River. Brandon Satinsky, a doctoral student in Microbiology at UGA claims, “the scientific community as a whole can draw new conclusions or study different aspects from the data sets.” “It’s the first time we’ve had this kind of data, at this devel of detail, and so now we can share with teams of modelers to help them make better predictions about the future of the system,” Moran says.
