How my work benefits society
Understanding the global carbon cycle, or how carbon moves through the land, ocean, and atmosphere and where it is stored, is important for fully understanding climate change and how humans are affecting climate. One aspect of the carbon cycle that isn’t well understood is how much carbon is stored in rivers and floodplains. There may be more carbon in rivers and floodplains than previously thought, which is important for determining the movement of carbon between the land, ocean, and atmosphere. As rivers transport sediment and organic matter, they can deposit those materials in their floodplains, storing carbon. I am quantifying that storage in the boreal (subarctic) zone through research on floodplains in the Yukon Flats National Wildlife Refuge in interior Alaska. My research will inform how geomorphology and hydrology influence carbon dynamics.
