The Alaska Region represents a resource-rich, dynamic landscape shaped by volcanoes, earthquakes, major rivers, and glaciers. Here, we conduct research to inform management of Alaska’s extensive natural resources, inform national Arctic energy policy, and provide scientific information to help others understand, respond to, and mitigate impacts from natural hazards.View Centers and Observatories
The Alaska Resource Data File (ARDF) site provides descriptions of mines, prospects, and mineral occurrences for individual U.S. Geological Survey 1:250,000-scale quadrangles in Alaska.
Several Research areas are listed and their contacts regarding Glacial Aquifer System Groundwater Availability Study are available here.

The Molecular Ecology Laboratory applies genetic and genomic technologies to address a variety of complex questions and conservation issues facing the management of the Nation's fish and wildlife resources. Together with our partners, we design and implement studies to document genetic diversity and the distribution of genetic variation among individuals, populations, and species. Information...
The Alaska Mapping Executive Committee (AMEC) meets regularly to coordinate on critical Alaska topographic mapping activities. Executives from 15 Federal agencies and the State of Alaska are combining efforts to acquire new digital elevation, hydrography, transportation, shoreline and geopositional data for Alaska, and create a new digital topographic map series for the State.
The Alaska Mapping Initiative is a U.S. Geological Survey effort to generate new topographic maps of Alaska. The USGS is coordinating with the State of Alaska and multiple Federal agencies to acquire updated digital map layers such as elevation, surface water, roads, and boundaries, and to create a modern series of digital maps for Alaska using these updated layers.
Scientists perform a range of studies that document, assess, and model coastal change, risk, and vulnerability. Studies include historical shoreline change, the geologic structure and history of coastal regions, sediment supply and transport, sea-level rise, and how extreme storm events affect rates and impacts of coastal change.
We study the distribution and hazard potential of coastal and submarine events such as earthquakes and submarine landslides and associated tsunami potential, hurricane induced coastal inundation, extreme storms, sea-level rise and oil and gas spills. We also model development to help evaluate and forecast coastal hazard probability and occurrence.
Our scientists conduct research studies focused on geologic mapping, sampling and understanding of mineral and energy resources and studies of the geologic setting and processes to inform renewable energy development offshore.
We bring together multidisciplinary expertise focused on developing tools and models to improve understanding of how healthy ecosystems function as well as how they respond to environmental changes and human impacts including ecosystem restoration. Research studies address coral reef, coastal wetland, benthic habitat and groundwater resources.
The Volcano Hazards Program develops long-range volcano hazards assessments. These includes a summary of the specific hazards, their impact areas, and a map showing ground-hazard zones. The assessments are also critical for planning long-term land-use and effective emergency-response measures, especially when a volcano begins to show signs of unrest.
The Alaska region oversees five volcano observatories located across the Western U.S. Each has a unique role to help emergency responders and the public prepare and respond to volcanic hazards such as ash, lava, and lahars.
This program responds to volcanic crises worldwide. Upon request of host countries, a team of scientists can rapidly respond to reduce fatalities and economic losses. Our scientists also work with international partners to improve monitoring and understanding of volcanic hazards.
Radar data is being collected statewide for Alaska under direction of the USGS 3D Elevation Program (3DEP). The new data is vastly improving the accuracy and resolution of elevation data for the state, and is being collected using an airborne Interferometric Synthetic Aperture Radar (IfSAR) sensor. USGS and the State of Alaska maintain web-based status maps and download services.
The 3DEP products and services available through The National Map consist of lidar point clouds (LPC), standard digital elevation models (DEMs) at various horizontal resolutions, elevation source and associated datasets, an elevation point query service and bulk point query service. All 3DEP products are available, free of charge and without use restrictions.
Many volcanoes in the U.S. are monitored by arrays of several instruments that detect subtle movements within the earth and changes in gas and water chemistry. The Volcano Hazards Program streams this data to its Volcano Observatories and makes it available on volcano-specific websites.
This is a new tool for understanding and communicating risks. The activities include the development of risk models and approaches to improve the situational awareness of communities and industries to natural hazards and reduce the uncertainty of those risk assessments.
Reports of ash fall are important to us; we use your observations to assess the character and size of an eruption plume. We report these data to the National Weather Service so they can keep their Ashfall Advisories current. Additionally, reports of NO ashfall during an eruption with expected ashfall are also important to us.
Consistent synthesis, integration, storage, and availability of fundamental data is critical to meeting the needs of USGS Science. We develop databases for hydrography, topography, invasive species, water resources, and many other datasets utilized by resource managers.
New US Topo maps for Alaska are being produced statewide, with digital 7.5 minute 1:25,000-scale maps providing a comprehensive update to the 15-minute 1:63,360-scale printed maps produced nearly fifty years ago. You can view a status map showing where the new maps are available, and link to a site to download the maps.
This portal is a “go to” source for maps related to ocean and coastal mapping. Information is organized by geography or region, by theme, and by the year data was published.

Key Messages Arctic summer sea ice is receding faster than previously projected and is expected to virtually disappear before mid-century. This is altering marine ecosystems and leading to greater ship access, offshore development opportunity, and increased community vulnerability to coastal erosion.

In the past decade, the development of the Barnett, Eagle Ford, Marcellus, and other shales has dominated the national consciousness regarding natural gas. But in Alaska, another form of natural gas has been the focus of research for decades—methane hydrate.
USGS scientist James “Barry” Grand, Ph.D., has been named a 2016 U.S. Fish and Wildlife Service Recovery Champion (Region 7) for his exemplary long-term research on two formerly threatened species, the spectacled eider and Alaska-breeding Steller’s eiders.
The USGS continues to collect high resolution elevation data, contributing to greatly improved Alaska map data
A new study led by the U.S. Geological Survey and the University of Wyoming found that increased westward ice drift in the Beaufort and Chukchi seas requires polar bears to expend more energy walking eastward on a faster moving “treadmill” of sea ice.
Thanks to a quarter-century of research and monitoring, scientists now know how different wildlife species were injured by the 1989 Exxon Valdez oil spill and how long it took for populations to recover.
Ducks in North America can be carriers of avian influenza viruses similar to those found in a 2016 outbreak in Indiana that led to the losses of hundreds of thousands of chickens and turkeys, according to a recent study.
Which U.S. State or territory has more large earthquakes than the rest of the United States combined?
While freshwater ecosystems cover only a small amount of the land surface in Alaska, they transport and emit a significant amount of carbon, according to new U.S. Geological Survey research. An invited feature article for Ecological Applications provides the first-ever major aquatic carbon flux assessment for the entire state. Carbon flux refers to the rate of carbon transfer between pools.
Look, in the sky! It’s a bird! It’s a plane! It’s...underground mineral research?
Managing 72 million acres of Federal lands in Alaska is not easy, especially when the land’s many uses need to be balanced. There are several competing interests, including the development of mineral resources that are critical to the American economy.
Wild ducks and shorebirds do not appear to carry Newcastle disease viruses that sicken or kill poultry, according to a new study led by the U.S. Geological Survey.
