Multi-objective Modeling as a Decision-support Tool for Feral Horse Management Multi-objective Modeling as a Decision-support Tool for Feral Horse Management
Decisions related to controversial problems in natural resource management receive the greatest support when they account for multiple objectives of stakeholders in a structured and transparent fashion. In the United States, management of feral horses (Equus caballus) is a controversial multi-objective problem because disparate stakeholder groups have varying objectives and opinions...
Assessing the Northeastern Gulf of Mexico Microtidal Wetland System Change in the Apalachicola-Big-Bend Region Under Sea-Level-Rise: Model Inputs and Outputs Assessing the Northeastern Gulf of Mexico Microtidal Wetland System Change in the Apalachicola-Big-Bend Region Under Sea-Level-Rise: Model Inputs and Outputs
Using the Hydrodynamic-Marsh Equilibrium Model (Hydro-MEM), the wetlands system within the Apalachicola-Big-Bend region of Florida (FL) (Fig. 1) was assessed using three sea-level rise scenarios of intermediate-low (50 centimeters [cm] by 2100), intermediate (1 meter [m] by 2100), and intermediate-high (1.5 m by 2100) from the National Oceanic and Atmospheric Administration (NOAA). Hydro...
Microsatellite Loci for Mogollon Narrowheaded Gartersnake (Thamnophis rufipunctatus) and the Northern Mexican Gartersnake (Thamnophis eques megalops) in Arizona and New Mexico (2020-2021) Microsatellite Loci for Mogollon Narrowheaded Gartersnake (Thamnophis rufipunctatus) and the Northern Mexican Gartersnake (Thamnophis eques megalops) in Arizona and New Mexico (2020-2021)
The Mogollon Narrowheaded gartersnake (Thamnophis rufipunctatus) and the Northern Mexican gartersnake (Thamnophis eques megalops) are both listed as Threatened under the Federal Endangered Species Act. Both species have a strong association with aquatic habitats, and these habitats have been highly altered from impoundments, land-use changes, and the introduction and spread of non-native...
Geochemical Data Release for Idaho Primitive Area, including the contiguous Clear Creek-Upper Big Deer Creek Area, the Salmon River Breaks Primitive Area, the Sawtooth Primitive Area, and adjacent areas, central Idaho (ver. 1.2, June 2022) Geochemical Data Release for Idaho Primitive Area, including the contiguous Clear Creek-Upper Big Deer Creek Area, the Salmon River Breaks Primitive Area, the Sawtooth Primitive Area, and adjacent areas, central Idaho (ver. 1.2, June 2022)
This U.S. Geological Survey (USGS) data release (ver. 1.2, April 2022) contains a set of previously unpublished geochemical data from project studies of primitive areas in central Idaho, including the Clear Creek-Upper Big Deer Creek Area, the Salmon River Breaks and Sawtooth Primitive Areas, and the Gospel-Hump Wilderness Area. The purpose of the USGS Idaho Primitive Area studies...
Current-use pesticides, nutrients, chloride, and metals in ponds and stormwater basins of the New Jersey Pinelands, 2018-20 Current-use pesticides, nutrients, chloride, and metals in ponds and stormwater basins of the New Jersey Pinelands, 2018-20
The data presented in this data release include concentrations of current-use pesticides, nutrients, chloride, and metals in surface water collected from 60 wetlands including natural ponds, excavated ponds (Xponds), and stormwater basins in the New Jersey Pinelands, 2018-20. Site information, basic water-quality parameters, and method information also are included.
Solid and aqueous geochemistry for mill tailings and other ore processing materials Solid and aqueous geochemistry for mill tailings and other ore processing materials
These worksheets contain data from geochemical analyses of solid mill tailings and other ore processing materials from worldwide localities, and leachates from those samples.
Gridded earthquake ground motions for the 2023 AASHTO Design Specifications Gridded earthquake ground motions for the 2023 AASHTO Design Specifications
For designing bridges to safely resist earthquakes, the 2023 editions of the AASHTO (1) Guide Specifications for LRFD Seismic Bridge Design, (2) LRFD Bridge Design Specifications, and (3) Guide Specifications for Seismic Isolation Design provide risk-targeted design ground motions via this data release and the corresponding USGS Seismic Design Web Services (listed below). The web...
Spatial Coverage for Estimated Baseflow for Streams Containing Endangered Atlantic Salmon in Maine, USA (version 1.1, June 2022) Spatial Coverage for Estimated Baseflow for Streams Containing Endangered Atlantic Salmon in Maine, USA (version 1.1, June 2022)
The U.S. Geological Survey (USGS) developed a regression model for estimating mean August baseflow per square mile of drainage area in cooperation with National Oceanic and Atmospheric Administration (NOAA) to help resource managers assess relative amounts of baseflow in streams with Maine Atlantic Salmon habitat (Lombard and others, 2021). The model was applied to each reach of a stream...
Whole Rock Major and Trace Element Chemistry for Igneous and Sedimentary Rocks from the Western Alaska Range, Alaska Whole Rock Major and Trace Element Chemistry for Igneous and Sedimentary Rocks from the Western Alaska Range, Alaska
This data release contains whole rock major and trace element data for 399 igneous and sedimentary rock samples collected from the Western Alaska Range between 1968 and 2014 and funded by the Mineral Resources Program of the U.S. Geological Survey. All materials were analyzed by ALS Global, between 2014 and 2018, by a range of different techniques, so multiple unique entries for a given...
Carbon dioxide and methane fluxes with supporting environmental data from coastal wetlands across Cape Cod, Massachusetts (ver 2.0, June 2022) Carbon dioxide and methane fluxes with supporting environmental data from coastal wetlands across Cape Cod, Massachusetts (ver 2.0, June 2022)
Saline tidal wetlands are important sites of carbon sequestration and produce negligible methane (CH4) emissions due to regular inundation with sulfate-rich seawater. Yet, widespread management of coastal hydrology has restricted vast areas of coastal wetlands to tidal exchange. These ecosystems often undergo impoundment and freshening, which in turn cause vegetation shifts like invasion...
Great Lakes Research Vessel Catch (RVCAT) Database Great Lakes Research Vessel Catch (RVCAT) Database
The Great Lakes Research Vessel Catch (RVCAT) database is managed at the Great Lakes Science Center (GLSC). RVCAT has been used as the primary data collection tool aboard the GLSC?s research vessel operations across the Great Lakes.

Surface Elevation Table Measurements at Five Tidal Marshes Across the San Francisco Bay-Delta (2016-2019) Surface Elevation Table Measurements at Five Tidal Marshes Across the San Francisco Bay-Delta (2016-2019)
Surface elevation tables with marker horizons (SET-MH) measure millimeter-scale changes in elevation over time. A combination of pin measurements (elevation change) and surface deposition measurements (marker horizon) is used to distinguish elevation changes due to belowground and aboveground processes. SET-MHs were installed in 2016 and were measured quarterly across five tidal marshes...
