Glaciers are pristine watersheds. The runoff from glaciers can also support unique and productive watersheds. As part of a collaborative effort the Raymond laboratory is looking into how the input of organic matter to glaciers and snowpack. Recent work by our group has identified a significant fossil fuel component to snow and ice carbon. We are working on determining how ubiquitous this is and what it means to downstream ecosystems.
