Aerial view of a large walrus haulout on the northwestern shores of Alaska. The image was taken using an unoccupied aerial system, commonly referred to as a survey drone. This survey was flown to collect imagery of walruses resting on shore for purposes of estimating the abundance of walruses that use the U.S. Chukchi Sea waters during the autumn.

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.

Ice-rich permafrost exerts a strong control on hydrology in Arctic regions because it limits infiltration, leading to large runoff events.

North fork of the Agashashok River located in Noatak National Park and Preserve, Alaska. Recent observations from Arctic Alaska indicate that waters draining permafrost landscapes may be susceptible to iron and carbon mobilization following thaw.
