A misty morning in the headwaters of the Akillik River, Alaska

A misty morning in the headwaters of the Akillik River, Alaska. This work is part of the Hydro-Ecology of Arctic Thawing (HEAT): Hydrology project that takes place in the Arctic Network Parks because they lie in a region that is rapidly warming. This study focuses on headwater streams because they are more susceptible to hydrologic changes than larger rivers, control the flux of solutes and nutrients from the land to rivers and the ocean, and provide critical habitat and food resources to juvenile fish.
