The observed rate of warming in many National Park Service (NPS) lands in Alaska has accelerated soil subsidence and increased landslide frequency, thereby threatening public access, subsistence activities and infrastructure in NPS regions. Areas most affected by this change are along the Denali Park Road, the proposed Ambler Road through Gates of the Arctic National Park and Preserve, and the McCarthy Road in Wrangell – St. Elias National Park and Preserve. In light of this, resource managers need highly accurate, localized climate information to assess and plan for future landslide hazards. This project addresses concerns and management implications in these focus areas with emerging issues that have been outlined...

High latitude northern ecosystems are currently warming twice as fast as the global average. Over the last several decades, this has caused dramatic losses of frozen area in the Arctic and sub-Arctic. However, it is unclear how melting coastal mountain glaciers, thawing permafrost, and declines in snowpack will affect the quality of freshwater habitat for culturally and economically important salmon in Alaska. As a collaborative effort with the Alaska Department of Fish and Game, the Alaska Department of Natural Resources, and the U.S. Fish and Wildlife Service, this project aims to answer three questions: How does melting affect the freshwater habitat of Pacific salmon? How will changes to aquatic flows...

Scientific information can be used to help individuals, communities, and governments alike make more informed decisions. However, for people to become aware of the science that could inform their decisions and its relevance to their lives and decisions, it must be communicated effectively. Multiple obstacles prevent this from happening, including scientists’ lack of time and communication expertise, among other barriers. This pilot project is a novel internship program that pairs student interns with USGS scientists to assist with field-based natural or physical science research in Alaska, while also providing support to the teams of interns and scientists to generate creative and durable science communication products...

Steep, mountainous watersheds, dramatic climate gradients, and tight links between the land and sea are common features of both the Pacific Islands and Southeast Alaska. In these "ridge-to-reef" and “icefield-to-ocean" ecosystems, environmental changes that occur at higher elevations have downstream impacts on the waters below. Today, these two ecosystems are undergoing changes in climate that are significantly impacting the terrestrial, freshwater, and coastal ecosystems that communities rely on for food, water, recreation, and tourism. For example, changing weather patterns are leading to more frequent and severe extreme storms, atmospheric rivers, droughts, and heat waves. Communities in both regions have deep...
