Aquifer framework datasets used to represent the Central Oklahoma aquifer, Oklahoma Aquifer framework datasets used to represent the Central Oklahoma aquifer, Oklahoma
The Central Oklahoma aquifer underlies an area of about 2,900 square miles in central Oklahoma. The aquifer is in the Central Lowland Physiographic Province and consists of Garber Sandstone and the Wellington Formation, which are part of the Sumner Group of Permian age. The maximum thickness of the aquifer is about 1,000 feet with a saturated thickness ranging from 150 to 650 feet. The...
Aquifer framework datasets used to represent the Roswell Basin aquifer system, New Mexico Aquifer framework datasets used to represent the Roswell Basin aquifer system, New Mexico
The Roswell Basin aquifer system is located in southeastern New Mexico. It is composed of an alluvial aquifer and an underlying carbonate-rock aquifer. The aquifer covers an area of about 2,200 square miles and the alluvial aquifer covers about 1,200 square miles of the eastern half of this area. The alluvial aquifer primarily consists of Quaternary sediments and the carbonate-rock...
Aquifer framework datasets for the Willamette Lowland basin-fill aquifer, Oregon and Washington Aquifer framework datasets for the Willamette Lowland basin-fill aquifer, Oregon and Washington
The Willamette Lowland basin-fill aquifers (hereinafter referred to as the Willamette aquifer) is located in Oregon and in southern Washington. The aquifer is composed of unconsolidated deposits of sand and gravel, which are interlayered with clay units. The aquifer thickness varies from less than 100 feet to 800 feet. The aquifer is underlain by basaltic-rock. Cities such as Portland...
Aquifer framework datasets used to represent the Ada-Vamoosa aquifer, Oklahoma Aquifer framework datasets used to represent the Ada-Vamoosa aquifer, Oklahoma
The Ada-Vamoosa aquifer resides in the Central Lowland Physiographic Province in east-central Oklahoma and ends at the Kansas State line. The aquifer underlies an area of about 2,300 square miles. The aquifer consists mainly of layers of fine to coarse-grained sandstone irregularly interbedded with shale and limestone. The rocks are in the Ada and the Vamoosa Groups are Pennsylvanian age...
Aquifer framework datasets used to represent the Marshall aquifer, Michigan Aquifer framework datasets used to represent the Marshall aquifer, Michigan
The Marshall aquifer underlies much of the Lower Peninsula of Michigan and has a maximum thickness of 493 feet (Lampe, 2009). The aquifer consists mainly of medium-grained sandstone and is overlain by Pennsylvanian-age rocks and glacial deposits and underlain by the Devonian-Mississippian-age confining unit. The Marshall aquifer is one of the most productive aquifers in the state where
Postfire Seedlings and Resprout Recruitment by Ceanothus Postfire Seedlings and Resprout Recruitment by Ceanothus
These data summarize postfire resprouts and seedling counts for Ceanothus species in subgenus Ceanothus based on published data that is cited and personal observation by the author and other co-authors of the publication.
Sensor data from debris-flow experiments conducted in June, 2016, at the USGS Debris-flow Flume, HJ Andrews Experimental Forest, Blue River, Oregon Sensor data from debris-flow experiments conducted in June, 2016, at the USGS Debris-flow Flume, HJ Andrews Experimental Forest, Blue River, Oregon
These data were collected as part of a long-term program of large-scale experimentation at the USGS debris-flow flume. The chief focus of the six experiments performed in 2016 and represented in this data set was twofold: (1) measurement of evolving basal stresses as the flume headgate opened, and (2) measurement of broadband seismic energy radiated by the moving debris flows. The...
Landslide Inventory for Kosrae, Federated States of Micronesia (FSM) 2005 - 2023 Landslide Inventory for Kosrae, Federated States of Micronesia (FSM) 2005 - 2023
Landslides hazards pose a serious threat to people and infrastructure in the Federated States of Micronesia (FSM). To develop a comprehensive understanding of the landslides hazards in FSM, the USGS-USAID Landslide Disaster Assistance Team (LDAT) has put together landslide inventories for each state using satellite imagery. Mapping was done using RGB satellite imagery from Maxar, Planet...

Data includes species cover of cheatgrass (BRTE) and Russian thistle (SATR), as well as functional group cover of Sandberg's bluegrass (POSE), bare ground, litter, and shrubs for the year of 2021.
Aquifer framework datasets used to represent the Arbuckle-Simpson aquifer, Oklahoma Aquifer framework datasets used to represent the Arbuckle-Simpson aquifer, Oklahoma
The Arbuckle-Simpson aquifer covers an area of about 800 square miles in the Arbuckle Mountains and Arbuckle Plains of South-Central Oklahoma. The aquifer is in the Central Lowland Physiographic Province and is composed of the Simpson and Arbuckle Groups of Ordovician and Cambrian age. The aquifer is as thick as 9,000 feet in some areas. The aquifer provides relatively small, but...
Gridded gravity, magnetic, and pseudogravity data of the Sierra Nevada, California and Nevada Gridded gravity, magnetic, and pseudogravity data of the Sierra Nevada, California and Nevada
This data release presents gridded data associated with the geologic and geophysical maps of the Sierra Nevada Digital Earth Science Atlas led by the California Geological Survey and U.S. Geological Survey. Grids are provided in ASCII and geotiff formats. Complete Bouguer and isostatic gravity data were gridded from nearly 29,000 gravity measurements to provide information on crustal...
