Alaska Earth Mapping Resources Initiative (Earth MRI)

Our objective is to provide a strategic framework for planning, coordination, and execution of the USGS Earth Mapping Resources Initiative (Earth MRI) in Alaska. Earth MRI aims to improve knowledge of the U.S. geologic framework through new geological and geophysical mapping and to identify areas that have the potential to contain undiscovered critical mineral resources.

Eighteenmile Creek Area of Concern Fish Community Assessment

Background: Eighteenmile Creek was designated as an Area of Concern (AOC) in 1985 because water quality and bed sediments were contaminated by past industrial and municipal discharges, waste disposal, and pesticide usage. Five Beneficial Use Impairments (BUIs) were identified in the Eighteenmile Creek AOC, including BUI #3 - the degradation of fish and wildlife populations. The remedial action...

Earthquake Hazards in Southeastern Alaska

Over the last 100 years, the Queen Charlotte-Fairweather fault system has produced large-magnitude earthquakes affecting both Canada and the U.S. To fill in missing details about its offshore location and structure, USGS uses sophisticated techniques to truly understand the fault’s hazard potential.

Seabird Die-offs in Alaska

Beginning in 2015, large numbers of dead seabirds have been appearing on beaches in most marine areas of Alaska. Although seabird die-offs are known to occur sporadically (e.g. 1970, 1989, 1993, 1997/1998, and 2004) in Alaska, these recent die-offs have been distinguished from past events by their increased frequency, duration, geographic extent, and number of different species involved.

Meteor Crater is a 180 m deep, 1.2 km diameter bowl-shaped impact crater in Northern Arizona, and has long been a terrestrial analog site for planetary exploration. During the 1960’s, Eugene Shoemaker trained NASA astronauts at the crater to prepare for the Apollo missions to the Moon. The Meteor Crater Sample Collection consists of geologic samples from the Meteor Crater ejecta blanket.
