Scientists measuring discharge and collecting water chemistry samples

Detailed Description

USGS and NPS scientists measuring discharge and collecting water chemistry in small tributary to the Cutler River in the early summer. 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. Read more about this study here.
