Tabular uranium-lead and trace-element compositional data of zircons and whole-rock geochemistry of plutonic rocks in the Sierra Nevada, California Tabular uranium-lead and trace-element compositional data of zircons and whole-rock geochemistry of plutonic rocks in the Sierra Nevada, California
This dataset consists of zircon uranium-lead (U-Pb) isotopic compositions, ages, and trace-element compositions in addition to whole-rock chemical compositions from plutons within the Sierra Nevada, California. These samples primarily collected from 2015 to 2023, although some legacy data are included. Zircon crystals were analyzed using the Sensitive High-Resolution Ion Micro-Probe...
Water and sediment geochemistry in the Gallinas Creek Watershed, New Mexico following the Hermits Peak-Calf Canyon fire 2022-2023 Water and sediment geochemistry in the Gallinas Creek Watershed, New Mexico following the Hermits Peak-Calf Canyon fire 2022-2023
This data set was collected throughout the Gallinas watershed in New, Mexico following the Hermit's Peak-Calf Canyon fires on April 6, 2022. The watershed has a history of mining and prospecting, which acts as an additional stressor to post-wildfire water quality and ecosystem health. Water samples were collected immediately post-fire. Water, sediment deposit and bed sediment samples...
Ground-Based LIDAR Data of a Section of the Point Bonita Lighthouse Trail, Golden Gate National Recreation Area, Marin County, California, January 23, 2025 Ground-Based LIDAR Data of a Section of the Point Bonita Lighthouse Trail, Golden Gate National Recreation Area, Marin County, California, January 23, 2025
A rockfall occurred between the night of January 5 and the morning of January 6, 2025 on the Point Bonita Trail in the National Park Service Golden Gate National Recreation Area, California. The rockfall originated from a granodiorite rock face in the Franciscan Formation and deposited approximately 25 cubic meters of rock on the pedestrian trail below. The U.S. Geological Survey...
A revised inventory of landslides triggered by the March 11, 2011 M9.1 Tohoku Earthquake A revised inventory of landslides triggered by the March 11, 2011 M9.1 Tohoku Earthquake
Revised dataset of landslides triggered by the 2011 M9.1 Tohoku earthquake. Point data are presented as a csv with new failure types, source type, and impacts to the build environment classification for mapped landslides. This dataset is an extension of the Wartman et al. (2013) landslide inventory following the Tohoku earthquake, and includes the original landslide IDs and type...
P- and S-Wave Suspension Velocity Logs in the San Francisco Bay Region, Alameda, Santa Clara, and Sonoma Counties, California P- and S-Wave Suspension Velocity Logs in the San Francisco Bay Region, Alameda, Santa Clara, and Sonoma Counties, California
This data release contains P- and S-wave velocity data from logs of nine wells in three large sedimentary basins in the San Francisco Bay region. The logs were collected between 2000 and 2006 for the U.S. Geological Survey under contract by R.A. Steller of GeoVision using an Oyo suspension logging system. Well depths range from 215 to 407 meters and sample spacing in the wells ranges...
Composite multibeam bathymetry surface of the northern Cascadia Margin offshore Washington Composite multibeam bathymetry surface of the northern Cascadia Margin offshore Washington
Composite 30-m resolution bathymetric surface of northern Cascadia Margin offshore Washington. The surface was generated from various publicly available bathymetric datasets available in the region. The surface is available as a geoTIFF file.
