A proposed seismic velocity profile database model A proposed seismic velocity profile database model
We describe the data model that we intend to use in a publicly available site profile database under development for the United States. The initial implementation of the database contains data from California. Currently, our prototype data model consists of JavaScript Object Notation (JSON) format files for storing metadata and data. For a site to be included in the database, the minimum...

A geophysical characterization of the structural framework of the Camas Prairie Geothermal System, southcentral Idaho A geophysical characterization of the structural framework of the Camas Prairie Geothermal System, southcentral Idaho
Play Fairway Analysis methods, utilizing existing geologic, thermal, geochemical, and geophysical data were employed in an initial assessment of geothermal resources in the Snake River Plain. These efforts identified the Camas Prairie in southcentral Idaho as a region with elevated resource potential. Subsequent efforts included structural and geophysical data collection to identify the...

Geothermal potential of the Umatilla Indian Reservation, Oregon: Evidence from detailed geophysical investigations Geothermal potential of the Umatilla Indian Reservation, Oregon: Evidence from detailed geophysical investigations
Recent geologic and geophysical investigations were undertaken in northeastern Oregon to better assess earthquake hazards in the region and determine relative favorability for geothermal energy development on lands of the Confederated Tribes of the Umatilla Indian Reservation (CTUIR). This work was funded in part by a Bureau of Indian Affairs grant awarded to the CTUIR to identify areas...

Effects of rearing environment on behavior of captive-reared whooping cranes Effects of rearing environment on behavior of captive-reared whooping cranes
Whooping cranes (Grus americana) are 1 of the most endangered bird species in North America. In 1999 the Whooping Crane Eastern Partnership was formed to establish a migratory population of whooping cranes in eastern North America. These efforts have been extremely successful in terms of adult survival but reproductive success post-release has been low. One hypothesis developed to...

Analysis of different sensor performances in impervious surface mapping Analysis of different sensor performances in impervious surface mapping
The U.S. Geological Survey (USGS) has developed the National Land Cover Database (NLCD) to provide consistent land cover and land cover change products for the nation since 2001. As one of products in the NLCD, the percent impervious surface area (ISA), which was estimated with Landsat imagery, represents the fraction of human-made impervious area in a 30-m grid and has been used to...

Automated road breaching to enhance extraction of natural drainage networks from elevation models through deep learning Automated road breaching to enhance extraction of natural drainage networks from elevation models through deep learning
High-resolution (HR) digital elevation models (DEMs), such as those at resolutions of 1 and 3 meters, have increasingly become more widely available, along with lidar point cloud data. In a natural environment, a detailed surface water drainage network can be extracted from a HR DEM using flow-direction and flow-accumulation modeling. However, elevation details captured in HR DEMs, such...
