Data

The database for the Washington West 30- by 60-minute quadrangle covers an area of approximately 4,884 square kilometers (1,343 square miles) in and west of the Washington, D.C., metropolitan area. The eastern part of the area is highly urbanized, and more rural areas to the west are rapidly being developed. The area lies entirely within the Chesapeake Bay drainage basin and mostly...

Observations and subtle shifts of aquatic vegetation communities in Lake Erie have USGS researchers concerned about the potential for grass carp and other threats to alter these vegetation communities. Assessing submersed aquatic vegetation (SAV) may contribute to inform the long-term impacts of grass carp, common carp, eutrophication, wind fetch and sedimentation on SAV communities...

The U.S. Geological Survey (USGS) developed and calibrated a Water Quality Analysis Simulation Program (WASP) model (version 8.4) for the Barnegat Bay-Little Egg Harbor Estuary (hereafter referred to as 'the Estuary'), New Jersey. This model was externally coupled with a previously developed hydrodynamic model (Defne and Ganju, 2015 and 2018) to simulate dissolved oxygen, nutrient...

These data consist of the behavioral responses of Pacific and Yellow-billed Loons to helicopter overflights and ground-based human activity in disturbed vs. undisturbed areas, as well as nest success in the summers of 2016 and 2017 at two field camps in the Fish Creek watershed, NPR-A.

These data are high-resolution bathymetry (riverbed elevation) and depth-averaged velocities in comma-delimited table format, generated from hydrographic and velocimetric surveys near highway bridge structures over the Missouri River in Kansas City, Missouri, on August 8–9, 2023. Hydrographic data were collected using a high-resolution multibeam echosounder mapping system (MBMS), which...

This data release contains the boundaries of assessment units, assessment input data, and resulting fact sheet data tables for the assessment of undiscovered oil and gas resources in Oman. The assessment unit is the fundamental unit used in the National and Global Oil and Gas Assessment Project for the assessment of undiscovered oil and gas resources. The assessment unit is defined...

This data release includes downscaled climate inputs and hydrologic outputs from the Basin Characterization Model (BCM) version 8 (v8), described in Flint et al. (2021a), in a 30 by 30-meter spatial resolution at a monthly time step from water years 1896 to 2023 for the upper Feather River watershed. This data release includes five child items: 1. 30-year summaries, 2. Model Archive, 3...

Scientists from the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center in St. Petersburg, Florida (USGS–SPCSMC), conducted a geophysical survey of the northern Chandeleur Islands, Louisiana during two survey legs: June 12-21 and July 31-August 11, 2023. During this study, multibeam bathymetry and sub-bottom geophysical data (Forde and others, 2024) were collected...

This data release contains one table with heat shock protein 70 (HSP70) abundance measurements of Pacific salmon (Oncorhynchus spp.) muscle samples, collected from fish occupying freshwater in various Alaskan watersheds. Water temperatures associated with a sampled fish are also included in the dataset, when available.

This U.S. Geological Survey (USGS) data release accompanies planned publication ‘Geochemistry and radiogenic isotopes constrain the mantle source region of the Mountain Pass Intrusive Suite, California' and planned data release 'Whole-rock geochemical and isotopic data for the Mountain Pass Intrusive Suite, California'. The data release includes laser ablation multi-collector inductively...

Presented here are bathymetric data collected from the Cuyahoga River at Gorge Metro Park. These data were collected September 25, 2024, from the Gorge Dam upstream for approximately 1.2 miles. The survey was completed using a marine-based mobile mapping unit that was deployed from the side of a jon boat. Data were georeferenced using an integrated RTK (real time kinematics) system...

The Ecology Section at the USGS, EESC, S. O. Conte Research Laboratory studied brook trout in a small coastal stream (Stanley Brook) from 2006 - 2013. The goal was to understand the mechanisms and consequences of anadromoy, as well as strength and direction of drivers on fish growth, movement, reproduction and survival in the wild. We hope to provide a comprehensive understanding of fish...
