Bathymetric survey and sedimentation analysis of Lago Patillas, Puerto Rico, August 2019 Bathymetric survey and sedimentation analysis of Lago Patillas, Puerto Rico, August 2019
In August 2019, the U.S. Geological Survey, in cooperation with the Puerto Rico Electric Power Authority, conducted a bathymetric survey of Lago Patillas to update stage-volume data in order to determine the sediment infill rates and to generate a bathymetry map. Water-depth data were collected along predefined lines using single-beam depth sounder and Differential Global Positioning...

Three-dimensional geologic map of the Brady geothermal area, Nevada Three-dimensional geologic map of the Brady geothermal area, Nevada
The three-dimensional (3D) geologic map characterizes the subsurface in the Brady geothermal area in the northern Hot Springs Mountains of northwestern Nevada. We built the 3D map by integrating the results from detailed geologic mapping, seismic-reflection, potential-field-geophysical, and lithologic well-logging investigations completed in the study area. This effort was undertaken to
