The maps provide a general overview of management, not ownership, as Federal and other designated areas may overlap state, private, and other inholdings. The maps include U.S. States only (not Territories) based on the PAD-US 2.1 Combined Proclamation (Tribal areas and military lands are provided for context), Marine, Fee, Designation, Easement feature class, published by the USGS Science Analytics and Synthesis (SAS), Gap Analysis Project (GAP). The All Managers and Federal Managers maps illustrate the land or marine management agency. The Protection Status map depicts GAP Status Code (a measure of management intent to...
Burnsville Cove in Bath and Highland Counties (Virginia, USA) is a karst region in the Valley and Ridge Province of the Appalachian Mountains. The region contains many caves in Silurian to Devonian limestone, and is well suited for examining geologic controls on cave location and cave passage morphology. In Burnsville Cove, many caves are located preferentially near the axes of synclines and anticlines. For example, Butler Cave is an elongate cave where the trunk channel follows the axis of Sinking Creek syncline and most of the side passages follow joints at right angles to the syncline axis. In contrast, the Water Sinks Subway Cave, Owl Cave, and Helictite Cave have abundant maze patterns, and are located near...

Using publicly available data for Madison and Oneida counties, New York, a series of geospatial overlays were created at 1:24,000 scale to examine the bedrock geology, groundwater table, soils, and surficial geology. Bedrock and surficial geology were refined using extant bedrock maps, well and borehole data from water- and gas-wells, soil data, and lidar data. Groundwater data were collected from New York State Department of Environmental Conservation and U.S. Geological Survey water-well databases to estimate the groundwater table. Soil data were used to examine soil thickness over bedrock and infiltration. An inventory of closed depressions was created using reconditioned lidar-derived bare-earth digital elevation...

This dataset represents 505 campsites along the Colorado River in Grand Canyon with associated debris flow probabilities calculated for approximately a 100-year period (Griffiths and others, 2004) and geomorphic attributes mapped by the U.S. Geological Survey, Grand Canyon Monitoring and Research Center (USGS-GCMRC) (Hadley and others, 2018). The campsite polygons were developed as part of a master campsite database that was a collaborative effort to maintain between the National Park Service in Grand Canyon National Park and the USGS-GCMRC. Debris flow probabilities have been added as an attribute from ungauged tributary watersheds published in 2004 (Griffiths and others, 2004). Area and percentages of campsites...

This study builds upon work conducted under the Great Lakes Fishery Commission (GLFC) Technical Assistance Program that was funded to prepare and evaluate an alternative solid formulation of the lampricide 3-trifluoromethyl-4-nitrophenol (TFM) in a laboratory flume. The project aligns within the lampricide theme in the Sea Lamprey Research Program by improving lampricide performance, efficacy, and safety through the development of a more environmentally compatible lampricide formulation compared to the current surfactant-based TFM bar. The study involved performing field applications of experimental TFM pellets manufactured by collaborators at Northland College (Ashland, WI). Applications were conducted on small...

Dreissenid management has focused primarily on chemical tools which are efficacious, but not without ecological or economic costs. There is a need for additional control tools that are less expensive, readily available, and will not leave a residue after treatment. Carbon dioxide has these advantages over chemical pesticides and has demonstrated effectiveness for control of a range of aquatic invasive species, including dreissenid mussels. Carbon dioxide was lethal to adult zebra mussels at levels that were safe to juvenile unionid mussels and lower levels cause detachment and gaping. Dreissenid veligers are more sensitive than adults to water quality conditions, including pH. Therefore, we hypothesized that effective...

In summer 2018, the U.S. Geological Survey partnered with the U.S Department of Energy and the Bureau of Ocean Energy Management to conduct the Mid-Atlantic Resources Imaging Experiment (MATRIX) as part of the U.S. Geological Survey Gas Hydrates Project. The field program objectives were to acquire high-resolution 2-dimensional multichannel seismic-reflection and split-beam echosounder data along the U.S Atlantic margin between North Carolina and New Jersey to determine the distribution of methane gas hydrates in below-sea floor sediments and investigate potential connections between gas hydrate dynamics and sea floor methane seepage. MATRIX field work was carried out between August 8 and August 28, 2018 on the...

This dataset represents 740 tributary canyons and/or watersheds adjacent to the Colorado River in Grand Canyon with associated debris flow probabilities from 2004. Also, these data include tributarys canyon and/or watersheds to Glen Canyon and several smaller watersheds in Grand Canyon where debris flow data is currently unavailable. Historic probabilities of debris flow occurrence were estimated by modeling the known frequency distribution with drainage basin parameters observed to control the process by which debris flows initiate and travel to the river. Observations from 1984 through 2003 provide a 20-year record of all debris flows that reached the Colorado River in Grand Canyon, and repeat photography provides...

Using high-resolution sonar technologies with geographic information systems (GIS) and object based image analysis, benthic characteristics of the Illinois River have been interpreted to support invasive carp research, monitoring and control. The study plan consisted of data collection and analysis of the Brandon, Dresden, Starved Rock, Marseilles, Peoria, La Grange and Alton reaches of the Illinois River. Reaches with larger aquatic areas (Peoria, La Grange and Alton), had areas prioritized for data collection and analysis.
This ArcGIS Add-In tool assigns telemetry receivers a “river address,” with the National Hydrography Dataset (NHD) flowlines providing the river name (analogous to a street name in a postal address) and a distance along flowline (the house number in a postal address). Using this information, it is possible to sequence receivers along a flowline. Once sequenced, receiver data can then be analyzed to identify where receivers are being bypassed by receiver tags, or if there are instances of improbable tag movement between receivers.

Migratory species often provide ecosystem service benefits to people in one country while receiving habitat support in other countries. The multinational cooperation necessary to ensure continued provisioning of these benefits by migrational processes may be informed by understanding the benefits that people in different countries derive from migratory wildlife. We conducted stated preferences surveys to estimate the willingness of respondents from Canada, the U.S., and México to invest in conservation for two migratory species, the northern pintail duck (Anas acuta) and the Mexican free-tailed bat (Tadarida brasiliensis mexicana). These data include characteristics of were conservation payments might occur, of...

This data release provides a digital inventory of the Robert S. Thompson packrat midden collection consisting of 1,740 midden samples and subsamples primarily collected in the Great Basin region of Nevada, as well as in Arizona, California, Colorado, Oklahoma, Utah, and Washington, USA, by Robert S. Thompson (USGS scientist emeritus) and others between 1977 and 2006. Middens are waste piles composed of the urine and feces of packrats (Neotoma spp.) also containing plant materials, bones, and insects. Radiocarbon dating of middens indicates they can be preserved for as long as 50,000 years, and their fossil plant assemblages document changes in plant community composition through time, providing important records...

A hydro-economic model was developed by coupling a three-dimensional groundwater flow model of the Harney Basin, southeastern Oregon (using MODFLOW 6) with a hedonic agricultural economic model. The hydro-economic model was used to investigate a set of hypothetical future scenarios having different groundwater pumpage conditions. The model looked at conditions 30 years beyond the 2018 conditions at the end of the HBGM transient simulation. This USGS data release contains all of the input and output files and needed Python scripts and JuPyter Notebooks for the simulations described in the associated journal article (https://doi.org/10.1029/2024WRXXXX)
