Soil Compaction and Erosion

Extensive off-highway vehicles (OHV) use on desert lands can directly and indirectly lead to human health problems and impact soil, vegetation, and wildlife habitat. Soil pulverization and loosening caused by OHVs contribute to dust hazards, and to respiratory illnesses and diseases (e.g., valley fever) in adjacent, downwind communities.  Repeated soil compaction by OHVs can also degrade...

Remote Sensing of Biological Soil Crusts

Biological soil crusts (biocrusts) occur in drylands globally where they contribute to ecosystem functioning by increasing soil stability, reducing dust emissions, and modifying soil resource availability (e.g., water, nutrients). Determining biocrust distribution and condition across landscapes continues to present considerable challenges to scientists and land managers. Biocrusts grow in...

Remote Sensing of Energy Development

Oil and gas development across the western United States has increased substantially in recent decades, including within the Colorado Plateau. The Colorado Plateau is a high desert region of grasslands, shrublands, and woodlands and is home to a large number of world-renowned national and tribal parks and monuments (e.g., Grand Canyon, Zion, Bryce, Arches, Canyonlands, Monument Valley, and...

Probabilistic Forecasting of Earthquakes, Tsunamis, and Earthquake Effects in the Coastal Zone

The nation's coastlines are vulnerable to the interrelated hazards posed by earthquakes, landslides, and tsunamis. In the marine environment these events often occur in concert, and distant triggers can cause severe local effects, making the issue global in scope. As the population continues to migrate toward the coastlines, the social impacts of these hazards are expected to grow.

Remote Sensing and Dryland Management

Approximately 35% of the US are drylands, including about 80% of all lands managed by Department of Interior. Drylands are strongly resource-limited, and have low resilience and resistance to disturbance, meaning small environmental changes often have disproportionally large ecological effect. Our research applies remote sensing and spatial analysis to characterize and monitor dryland...

Accessing usSEABED

Since the second half of the 20th century, there has been an increase in scientific interest, research effort, and information gathered on the geologic sedimentary character of the continental margins of the United States. Data and information from thousands of sources have increased our scientific understanding of the geologic origins of the margin surface, but rarely have those data been...

usSEABED data format and content

 

The USGS data release for the usSEABED database enables search and download of six interlinked files of output data and a seventh file that provides linked information about the original data sources. These files can be downloaded in their entirety and are also searchable through an online interface that allows for search and selection either through a GIS display or through a web...

Denali National Park Geohazards Geologic Mapping

Denali National Park (DENA) is a major draw for tourism and recreation and a major economic engine for central Alaska. However, the geologic forces that created the steep landscape of DENA also make it prone to geologic hazards (geohazards) like landslides, debris flows, and earthquakes. DENA has only one major road, called the ‘Park Road’, that serves nearly all of its infrastructure.
