The Amazon River contributes considerable freshwater and dissolved constituents to the global ocean, and its low-salinity plume offshore significantly impacts the carbon and nutrient cycles of the western tropical North Atlantic Ocean. Viewing the river-plume-ocean system as a continuum, rather than a point source, is a key component of the GBMF- and NSF-funded ROCA / ANACONDAS project effort. Here Yager will report on key findings of a multi-season field effort in the lower reach of the Amazon mainstem and offshore plume to determine the impact of the river on the regional and global carbon cycle. Combining microbial and geochemical data from the continuum improves our understanding of the links between the river, the plume, and the tropical Atlantic carbon cycle, as well as our predictive capabilities under future climate change. http://www.marsci.uga.edu/directory/patricia-l-yager
