Research Geochemist Renee Takesue combines geology and chemistry to shed light on how chemical components from natural and human-made sources make their way into coastal environments.
Climate Science Champions, Season 1: Mike Carey, Research Fish Ecologist
Detailed Description
Fish Ecologist Mike Carey studies the impacts beavers have on warming Alaskan permafrost landscapes.
As subarctic summers grow warmer and drier and winters less severe, Alaska’s tundra landscape is transforming. Plants and animals historically absent from the tundra are arriving and multiplying. One of these newcomers is the beaver, which is expanding its range north and west out of the boreal forest. Beavers’ ability to build dams and create wetlands is well-known in temperate regions. What USGS researchers want to understand is the impact beavers have on landscapes underlain by permafrost—the frozen ground that contains methane, carbon dioxide, and other greenhouse gases that contribute to global warming.
