Elizabeth Webb is a Master's student at the University of Florida. Her research in Alaska focuses on wintertime soil respiration. Specifically, she is looking at what factors drive wintertime respiration (temperature, moisture, etc.), how much carbon is coming out of the tundra during the winter, and how this will change with climate warming. More generally, Ms. Webb is interested in large-scale problems such as how land-use change is impacting global rivers and oceans, and how climate change is impacting the biosphere.
