Summary

Ecosystems spanning the zones from “ridge-to-reef" and “icefield-to-ocean” are home to relatively high levels of biodiversity; serve as conduits of nutrients to sensitive coastal environments; and are culturally and economically important to local communities. These systems are smaller and have unique geological and streamflow properties compared to more typical river systems and, because of this, it is not clear how they will respond to shifting climatic patterns. Both Hawaiian ridge-to-reef and Alaskan icefield-to-ocean ecosystems face the potential of climate-driven changes in extreme flow events, such as floods and droughts, that could dramatically change how critical nutrients are retained and transported. The overall goal [...]
