Emergence of the Sadlerochit Spring

September 2019 (approx.)

Detailed Description

The Sadlerochit Spring is one of a handful of small springs that provides liquid water to the North Slope of Alaska year round. Given that most other water sources in this region are frozen in the winter, springs provide critical habitat for fish and macroinvertebrates, and may play an outsized role in the regions hydrologic cycle. Recent work by the USGS measured discharge and water chemistry of surface waters in this region to understand the subsurface source of these springs and how they are changing in time.
