At 10:44:21 local time on December 5, 2024, a M 7.0 earthquake occurred approximately 70 km southwest of Ferndale, California, just west of the Mendocino Triple Junction. Starting the next day, the U.S. Geological Survey deployed nodal seismometers (nodes) in the Eel River Valley, near Cape Mendocino, and along the California Highway 101 corridor to compliment local permanent stations of...

Bed sediment samples were collected from the channels of 4 sites within northern San Francisco Bay, California, USA. The channels sampled were located in Corte Madera Bay, San Pablo Bay, Grizzly Bay and Suisun Bay. Sediment samples were collected with push cores, by subsampling a Gomex box corer. Cores, which ranged in length from 2 to 6 centimeters (cm), were sectioned by depth. The top...

Data were collected as part of a long-term capture-recapture program to assess the status and dynamics of populations of two long-lived, federally endangered catostomids in Upper Klamath Lake, Oregon and Clear Lake Reservoir, California. Lost River suckers (LRS; Deltistes luxatus) and shortnose suckers (SNS; Chasmistes brevirostris) have been captured and tagged with passive integrated...

This geospatial dataset describes the location and spatial coordinates of each site where invasive African clawed frogs Xenopus laevis were detected in western Washington state between 2015 - 2023.

This data release supports the publication: "Linking Fire Radiative Power to land cover, fire history, and environmental setting in Alaska, 2003 - 2022". The *.csv file contains data associated with fire radiative power (FRP) observations derived from 1-km MODIS data over Alaska from 2003 to 2022. The file allows users to replicate the statistical analysis of FRP values with vegetation...

This data release contains data for the associated publication: Timing and Abandonment of the Chemehuevi Formation: a Conspicuous Pleistocene Sedimentary Deposit of the Lower Colorado River

Over time, barrier islands may become eroded and experience land loss, which require management actions to restore island integrity. The process of restoring barrier islands can create new habitats but also alter existing habitats, which can impact the organisms depending on coastal habitats, such as the Endangered Species Act-listed Piping Plover (Charadrius melodus). Therefore, we...

Thucholites are unique organic features from igneous and sedimentary rocks composed of a U-C-rich interior enclosed by an organic outer shell. Here, we evaluated thucholites from the Ediacaran Salt Range Formation of the Upper Indus Basin in Pakistan using field emission scanning electron microscopy (FESEM) and nanoscale secondary ion mass spectroscopy (NanoSIMS). The thucholites can be...

Grasslands are an imperiled ecosystem, and grassland bird abundance is declining across North America. One of the strongest drivers for these declines is woody plant encroachment of grasslands. In the Great Plains and Sagebrush biomes of North America, spatial covariance—a remote sensing metric for tracking boundaries between vegetation types—is emerging as a new method to identify and...

The U.S. Geological Survey (USGS) deployed a series of oceanographic instruments at Madeira Beach, Florida configured to measure water levels, temperature, waves, and three-dimensional flow velocities throughout the water column. The instruments include (1) Spotter wave buoys with Smart Mooring (2) RBR pressure loggers, and (3) RDI Sentinel-V Acoustic Doppler Current Profilers (ADCP)...

The U.S. Geological Survey (USGS) conducted a study in cooperation with the Sonoma County Water Agency to assess the water resources of the SRPW and develop tools to better understand the groundwater and surface-water systems in the watershed. The foundation of these tools is the development and application of the Santa Rosa Plain hydrologic model (SRPHM) using GSFLOW to simulate...

Ratings are used for a variety of reasons in water-resources investigations. The simplest rating relates discharge to the stage of the river. From a pure hydrodynamics perspective, all rivers and streams have some form of hysteresis in the relation between stage and discharge because of unsteady flow as a flood wave passes. Simple ratings are unable to represent hysteresis in a stage...
