Data Releases

Geologic map geodatabase depicting the geology of the Greater Antilles and Virgin Islands region, including countries of Cuba, Haiti, Dominican Republic, and Jamaica, and territories of Puerto Rico, the U.S. Virgin Islands, the British Virgin Islands, and the Cayman Islands. Database tables include: geologic linework, dikes, folds, geologic units, and geochronologic data.

These data represent movement metrics of adult female grizzly bears and polar bears with and without cubs-of-the-year at seven temporal scales after den departure. Grizzly bear data were collected in the Greater Yellowstone Ecosystem during 2000–2021 and in the Northern Continental Divide Ecosystem during 2003–2022. Polar bear data were collected in the Southern Beaufort Sea during 1986...

This dataset is one table with data collected and derived from polar bears sampled in Alaska from the Southern Beaufort Sea subpopulation during 2000-2023. Collected data includes individual identity, location of observation, observation type, estimated birth year, and demographic information. Data were collected from polar bears that were captured, remotely sampled using biopsy darts...

This data release provides radiochemistry data (210Pb and 137Cs) of two sediment cores, BC01 and BC02, collected during USGS Field Activity 2024-662-FA in 2024 in San Francisco Bay, California, U.S.A., off Alameda and Point Isabel, respectively.

Small Uncrewed Aircraft Systems (sUAS) were used to collect aerial remote sensing data over Town Neck Beach, a highly trafficked local beach in Sandwich Massachusetts with parking lot, boardwalk, and state maintained sand and vegetation placement. USGS personnel collected natural (RGB) color images, LiDAR, and ground control points starting in December 2023 to support multiple science...

Small Uncrewed Aircraft Systems (sUAS) were used to collect aerial remote sensing data over Town Neck Beach, Massachusetts. The area is a highly trafficked public beach with parking lot, boardwalk, and renourishment and dune stabilization plan. On October 15th, 2024, USGS personnel collected natural (RGB) color images, lidar, ground control points, check points, and a vegetation height...

This data release contains frequency domain electromagnetic (FDEM) data collected during discrete times between July 2019 to October 2022 near Lake Placid, NY as part of a multi-method effort to monitor the effects of different road salt treatments on groundwater and the surrounding surface water (West Branch Ausable River). The FDEM instrument used was a Geophex GEM-2; a broadband...

This dataset accompanies manuscripts "Effects of sagebrush treatments on multi-scale resource selection by pygmy rabbits" (https://doi.org/10.1002/jwmg.51) and "Spatial ecology of refuge selection by an herbivore under risk of predation" (http://dx.doi.org/10.1890/ES11-00247.1). It is a single table that includes telemetry locations for 16 pygmy rabbits (Brachylagus idahoensis). The...

We synthesized existing literature to develop this dataset which relates suspended sediment concentration and exposure duration to biological effects on fishes. Our dataset contains a total of 3,610 dose-response data triplicates consisting of (a) suspended sediment concentration, (b) duration of exposure, and (c) fish severity of ill effects (SEV). There is no original data in the...

The purpose of this data release is to provide water quality data that were collected during a raft sampling campaign near USGS streamgage 372728107475701 (Animas River at Bakers Bridge north of Durango, CO) to USGS streamgage 09364500 (Animas River at Farmington, NM) between the dates 06/06/2022 and 06/10/2022. Chemical and physical parameters were collected at 1-minute intervals with...

IMPORTANT NOTE: This dataset includes spatial locations where streamflow permanence observations (continuous flow, discontinuous flow, and dry) were recorded using the FLOwPER (FLOw PERmanence) field survey available in the Survey 123 mobile data collection application. Additional information to describe the field conditions are included as part of the survey. Field observations in the...

The Santa Ana Sucker (Pantosteus santaanae) is a federally threatened species of ray-finned fishes endemic to the Santa Ana, San Gabriel, and Los Angeles Rivers in southern California. Seasonal limitations on conventional sampling and inconsistencies in survey methodologies have led to an incomplete understanding of Santa Ana Sucker population dynamics. Therefore, alternative sampling...
