Black Carbon Expert Sasha Wagner Joins Rensselaer
In the global carbon cycle, rivers are important players, pumping terrestrial carbon into the oceans. Ferried amid a cargo of dissolved organic matter – a category that encompasses molecules of things living, dead, and in the process of decay -- new sources of carbon enter the flow from a river’s headwaters to its mouth, while exposure to sunlight, microbes and other factors alter their original chemical structure along the route.
