Data

This data release contains porewater oxygen microprofiling data from abyssal sediment cores collected from the Samoa Basin in the South Pacific Ocean within the American Samoa Exclusive Economic Zone. Sediment cores were collected from 35 locations using a box core that was subsampled with push cores. Push cores were immediately transferred to a cold laboratory van, and oxygen was...

This data release presents portable X-ray fluorescence (pXRF) data and physical properties (grain density, saturated bulk density, dry bulk density, and magnetic susceptibility) of 30 rock samples collected from an Earth MRI survey area in northeastern Washington, USA. Rock type information (age and lithology) are also included. The rock samples were initially collected for low...

Campaign microgravity data have been collected at Kīlauea, Hawaiʻi, since 1975 to assess changes in mass associated with magmatic activity. The network of stations was disrupted by the 2018 summit collapse and was subsequently reestablished, with surviving and some new sites occupied regularly to track magmatic activity beneath the volcano. This data release includes microgravity data...

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

Bloater (Coregonus hoyi) are an extirpated deepwater fish species in Lake Ontario. Bloater were reintroduced to Lake Ontario starting in 2012 from a donor population in Lake Michigan. Despite annual stocking, Bloater have yet to establish a self-sustaining population and success of stocking has been limited. Acoustic telemetry studies have identified that post-release survival of stocked...

Lake Erie historically supported a large population of Cisco (Coregonus artedi) which provided an important fisheries resource. The Cisco population declined precipitously in the 1920s and by the 1960s the species was considered extirpated from the lake. In May of 2025, the New York State Department of Environmental Conservation experimentally released age-1 Cisco into Lake Erie to...

Wildfire can substantially alter the hydrologic response of watersheds to rainfall, and debris-flow activity is among the most destructive consequences of these events. To assist federal, state, and local agencies in planning for postfire hazards, the U.S. Geological Survey conducts debris-flow hazard runout assessments. This collection contains the results of those assessments conducted...

The U.S. Geological Survey (USGS) 3D Elevation Program (3DEP) has developed an integrated 1-meter topobathymetric digital elevation model (TBDEM) for the Potomac River extending from tidal Washington, D.C. to upstream of Hancock, Maryland. This is the third 3DEP pilot inland TBDEM, developed to produce a 3-dimensional surface elevation model that integrates topographic bare-earth...

The orthoimagery, digital surface model and point cloud presented here document conditions at Erie Ponds of the St. Louis River Area of Concern in Duluth, Minnesota in August 2020, prior to planned ecological restoration. Aerial images were collected using a DJI Phantom with FC6310 sensor at a nominal elevation of approximately 100 meters above the surface of the lake water. Data were...

The orthoimagery, digital surface model and point cloud presented here document conditions at Lincoln Park in Milwaukee, Wisconsin. Photos were collected in August 2021, prior to planned ecological restoration within the Milwaukee Estuary Area of Concern. Aerial images were collected using a DJI Phantom with FC6310 sensor at an elevation of approximately 100 meters above the study site...

This dataset provides precipitation intensity estimates for a one-year recurrence interval for the Continental United States as cloud-optimized GeoTIFFs (COGs). The release includes COGs for 15-minute, 30-minute, and 60-minute rainfall durations, and the precipitation intensities for these durations are referred to as I15, I30, and I60, respectively. Each raster reports precipitation...

Estimating individual age is important for defining the structure of fish populations (i.e., recruitment, growth, and mortality), including the assessment of many management objectives. Knowledge of the relative precision of age estimates using standard calcified structures is required to estimate the age of Grass Carp. Therefore, our objective was to evaluate the precision of annuli...
