These natural hazards are significant areas of concern as they threaten the lives of people and/or cause economic damage to Alaska villages along rivers and coast. Research activities move forward innovative means to monitor these hazards and conduct research on the underlying physical processes to improve short and long-term hazard assessments.
Scientists are conducting a variety of studies such as modeling Arctic barrier island, lagoon system response to projected warming, characterizing permafrost using remote sensing and ground-based geophysics, estimating rates of ocean acidification of the Arctic, and investigating possible degassing of permafrost associated with methane hydrates.
Knowledge of water availability, discharge patterns, and demand are essential to sustaining human life, ecosystem health, and economic viability. In Alaska, there are issues involving community potable water, salmon productivity, wetland dynamics, marine systems productivity, hazards, and environmental health.
The Alaska Region is the home for migratory fish, migratory birds under the International Treaty, marine mammals under the Marine Mammals Protection Act, species listed under the Threatened and Endangered Species Act, and those under review.
There are 169 potentially active volcanoes in the U.S., and the USGS Volcano Hazards Program provides warnings of unrest and eruption for these volcanoes. We offer volcano monitoring data, provide maps and geologic information, conduct research how volcanoes work, and engage with community education and outreach.
The AVO is a partnership among the USGS, the Geophysical Institute of the University of Alaska Fairbanks, and the Alaska Division of Geological and Geophysical Surveys. To mitigate volcanic hazards, AVO monitors and studies Alaska's hazardous volcanoes to forecast and record eruptive activity. AVO also monitors volcanic activity in the Commonwealth of the Northern Mariana Islands.
CalVO operates real-time volcano monitoring networks, disseminates forecasts and notifications of significant activity, assesses volcano hazards, researches volcano processes, and works with communities to prepare for volcanic eruptions in California and Nevada. The Observatory is located at USGS offices in Menlo Park, California.
HVO operates monitoring networks, assesses hazards, and issues notifications of volcanic activity and earthquakes in the State of Hawai‘i. HVO scientists conduct fundamental research on volcanic processes and work to educate the communities at risk. HVO is located in Hawaiʻi Volcanoes National Park on the Island of Hawaii.
A new report by the USGS finds that although snow geese are increasing rapidly in northern Alaska, they are not having a negative effect on black brant. Brant are a goose species that shares its nesting habitat with snow geese.
Despite recent changes to the growing season for plants in the Arctic, Alaska, caribou appear to have remained in sync with these changes over the last 30 years.
Bogoslof volcano, located in the Aleutian Islands about 98 km (61 mi) northwest of Dutch Harbor/Unalaska, is in an active eruption sequence that began in mid-December 2016 and continues today.
Scientists can now predict which avian species are most sensitive to the increasingly dominant shrub habitat spreading across Alaska, a capability that will be useful for natural resource agencies in Alaska charged with managing these resources.
A new study shows that harlequin ducks in coastal areas of Alaska’s Kodiak and Unalaska islands are exposed to environmental sources of mercury and that mercury concentrations in their blood are associated with their local food source, mainly blue mussels.
A recent interpretive review of scientific literature performed by the U.S. Geological Survey and the University of Rochester sheds light on the interactions of gas hydrates and climate.
The U.S. Geological Survey is pleased to announce the selection of Dr. Christian Zimmerman as the new director of their Alaska Science Center in Anchorage, Alaska. Zimmerman succeeds Dr. Mark Shasby who held the position for the past six years.
Water users around the country can now view the past and simulated future of hydrologic processes.
Caribou, North America’s wild reindeer, have lives apart from their famous role on Christmas Eve. Reindeer and caribou are large, cold-adapted, herding herbivores related to deer, elk and moose.
To learn more about how these arctic antler-bearers spend the other 364 days of the year, we talked to USGS caribou expert Dr. Layne Adams, who has studied these animals for more than 30 years.
ANCHORAGE, Alaska — This year marks the 50th anniversary of one of the longest continuous glacier research efforts in North America.
ANCHORAGE, Alaska — Some gulls in southcentral Alaska are carriers of antibiotic resistant strains of E. coli, according to a new study co-authored by the U.S. Geological Survey.
