Data Releases

The city of Santa Barbara, in cooperation with the U.S. Geological Survey (USGS) California Water Science Center, developed a three-dimensional density-dependent groundwater-flow and solute-transport model (the Santa Barbara Flow and Transport Model; Paulinski and others, 2018; Nishikawa and others, 2018). The Santa Barbara Flow and Transport Model met the objectives of estimating the

This data release includes thiamine concentration measurements from lake trout (Salvelinus namaycush) eggs and associated biological data (e.g., fish length, weight, sex) and capture location data (e.g., lake, coordinates, date of collection). Lake trout used in this dataset were collected during 2024 from across the Great Lakes and other inland lakes such as the Finger Lakes, New York...

This data release contains sediment core data including core imagery, multi-sensor core logger (MSCL) data, and grainsize data. As part of a multi-year project focused on characterizing offshore marine geohazards (tsunamis, earthquakes, and landslides), the U.S. Geological Survey (USGS) Coastal and Marine Hazards and Resources Program is collaborating with MBARI to conduct research along...

The area of study is restricted to the northern Appalachian region between latitudes 38N and 48N and longitudes 66W and 77W in the U.S. states of Maine, New Hampshire, Vermont, New York, Massachusetts, Connecticut, Rhode Island, Pennsylvania, and Delaware. This study (Wintzer and others, 2025) integrates data from several sources, including geologic, geochemical, geophysical, watershed...

This data release includes raster images of pre- and post-wildfire surface soil moisture modeled from Landsat Thermal-infrared and Sentinel-1A synthetic aperture radar for three fires that took place in the state of California (USA) between 2016 and 2017 and associated unburned, control locations for each wildfire. The model was trained and validated using In situ soil moisture data...

This dataset includes fish population and habitat data collected in 2025 to support development of the upper Santa Ana River Habitat Conservation Plan for the Santa Ana Sucker (Catostomus santaanae) and the Arroyo Chub (Gila orcuttii) in the Santa Ana River, California.

This project has inventoried and produced a digital database of Late Miocene through Holocene micropaleontologic slides and data available in the USGS collections along the lower Colorado River corridor, Imperial Valley, and Gulf of California. The digital database includes the location of samples, content of the samples, results of analyses, and other information in a format that can be...

This data release pertains to a seepage investigation conducted in order to compliment a dye tracing study at Oregon Caves National Monument in Josephine County, Oregon. The seepage dataset includes geospatial files of discharge measurement points and zero-flow observations along with vector lines delineating losing and gaining stream reaches. Hydrologic systems in karst environments...

This data release complements the following publication: D.E. Goldberg and others (2025). Ultralong, supershear rupture of the 2025 Mw 7.7 Mandalay earthquake reveals unaccounted risk. Science 390, 458-462. https://doi.org/10.1126/science.ady3581 It contains the preferred model results published in the manuscript referenced above. It also contains the input data and model parameters...

This data release contains output from a numerical snow simulation for a 166 kilometer (km) × 160 km model domain in the Qashqadaryo region of Uzbekistan. The simulation encompasses key watersheds within the region and uses SnowModel (Liston and Elder, 2006; Liston and others, 2020; Liston, 2020) to estimate the snow water resources and meteorology across the simulation domain. The...

As part of an effort by the U.S. Geological Survey (USGS) to better understand topographic and structural conditions that promote slow spreading and sagging of mountain ridges (Varnes and others, 1989), USGS researchers began surveying monitoring points at Bald Eagle ridge in the Sawatch Range of Colorado in 1975 (Radbruch-Hall and others, 1976; Varnes and others, 1990). Bald Eagle ridge...

The U.S. Geological Survey (USGS) Woods Hole Coastal and Marine Science Center deployed a four-legged bottom landing frame (nanopod) containing oceanographic instruments to collect measurements of winter wave conditions directly offshore of Marconi Beach in Wellfleet, MA. Supplementary sediment samples were collected to characterize grain size. Marconi Beach is the site of ongoing...
