The dataset represents benthic aquatic macoinvertebrates collected from eight streams to characterize production in Rio Grande cutthroat trout (Oncorhynchus clarkii virginalis; RGCT) populations throughout northern New Mexico from 2016 through to 2017. The macroinvertebrates were sampled using Hess samplers with a 250 micron mesh and all taxa were identified to the lowest level of taxonomic resolution.
The impacts of climate change on cold water species will likely manifest in populations at the trailing edge of their distribution. Rio Grande cutthroat trout (Oncorhynchus clarkii virginalis, RGCT) occupy arid southwestern U.S.A. streams at the southern-most edge of all cutthroat trout distributions; thus making RGCT particularly vulnerable to the anticipated warming and drying in this region. We collected stream temperature and stream drying to determine how these environmental constraints influence life-history trait expression (length- and age-at-maturity), demography, and extirpation risk in RGCT populations from northern New Mexico, U.S.A. We found the rate at which RGCT reached maturity was highest at warm...
During the winter of 2016 and the summer of 2018, the U.S. Geological Survey, Lower Mississippi-Gulf Water Science Center collected sediment cores for grain-size analysis in Mississippi and Arkansas. In a farm field adjacent to the Tallahatchie River near Money, Mississippi, 13 continuous sections of approximately 5-cm (2-in) diameter by approximately 1.5-m (5-ft) long sediment cores were extracted to better understand the sediment within the Mississippi River Valley alluvial aquifer. These data were used to support ongoing aquifer testing activities by the U.S. Department of Agriculture’s Agricultural Research Service. Lake Poinsett Dam is an earthen embankment dam located near Harrisburg, AR. In May of 2018, the...
The U.S. Army Corps of Engineers' Upper Mississippi River Restoration (UMRR) program, through its Long Term Resource Monitoring (LTRM) element, collected aerial imagery of the systemic Upper Mississippi River System (UMRS) during the summer of 2020. A Land Cover/Land Use (LCU) spatial database was developed based on the 2020 aerial imagery, which adds a fourth systemic-wide database to the existing 1989, 2000, and 2010/11 LCU databases. While a crosswalk was used to update the 1989 LCU database (originally developed using a different classification system), the 2000, 2010/11, and 2020 LCU databases share the same classification, making them directly comparable from a classification standpoint. Furthermore, protocols...

Remote camera data on snow presence, snow depth, and wildlife detections on Moscow Mountain in Latah County, ID, USA. Reconyx Hyperfire I and Hyperfire II cameras were used and set to take hourly timelapse images and motion-triggered images. The cameras were deployed from October 2020 - May 2021. Snow presence was assessed up to 15 m from the camera. Snow depth was measured using virtual snow stakes created with the edger R package created by the author. Wildlife were marked as present in all photos in which they appear, and new individuals were counted. Snow density was collected using a federal or prairie snow sampler. Snow hardness was collected using a ram penetrometer. Solar radiation was calculated using hemispherical...

This dataset contains the input files, script, and output files regarding 110 years of daily regulated (observed) and naturalized streamflow (million cubic meters/day) for ten gauge stations in the Rio Grande/Bravo basin. The gauge stations included are at Amistad, Anzalduas, Artesia, Below Presidio, Laredo, Conchos Outlet, Foster Ranch, Laredo, Pecos Outlet, Salado River, and San Juan River.
A raster dataset representing multi-year mean (1998-2018) capacity factors (CF) for a solar photovoltaic system based on current technology, for the Conterminous United States. These data are calculated using ½ hourly irradiance values from the National Solar Radiation Database (NSRDB) Sengupta et al. (2018), and the Systems Advisor Model (Blair et al. 2014). Cell values represent the estimated capacity factor (a ratio of net generation to the maximum generation) for photovoltaic energy production for a 1-axis tracking system (technology details found in Maclaurin et al. 2019). The continuous raster were put into 8 quantile bins for interpretation and reporting. For more information and further data, please visit...

Potential habitat for the gray bat (Myotis grisescens) in Oklahoma was derived from the published Gap Analysis Project (GAP) Species Habitat Map.
A raster dataset representing the soil organic carbon content of surface soil horizons (top 15 cm or ~6 inches) in the conterminous United States. Soil organic carbon is a readily component of soil organic matter, which plays an important role the functioning of soils, including formation of soil structure, soil nutrient content, soil moisture retention, and carbon sequestration. Soil carbon content here is measured as percent by mass. This dataset was created using the soil percent organic carbon 100 m spatial resolution predictive rasters for 0, 5, and 15 cm depths developed by Ramcharan et al. (2018). The average soil organic carbon over the top 15 cm was calculated using the trapezoidal rule, and then put into...

Publicly accessible open spaces provide valuable opportunities for people to exercise, play, socialize, and build community. People are more likely to use public open spaces that are close (ideally within walking distance) to their homes, and larger open spaces often provide more amenities. To assess the potential benefit of creating new open space in the southeast US, we identified areas without access to open space within a certain distance category (in this case, 0.5 miles). Then, for each 30-meter pixel in the study area, we then totaled the number of people within 0.5 miles who do not currently have access to open space within that distance. This represents the number of people who would benefit from new open...

Publicly accessible open spaces provide valuable opportunities for people to exercise, play, socialize, and build community. People are more likely to use public open spaces that are close (ideally within walking distance) to their homes. To assess the spatial distribution of access to open space for recreation in the southeastern United States, we constructed an index of open space access based on the size of the largest publicly accessible open space within 10 miles of each point on the landscape, using three distance categories to represent whether people can reach the open spaces by walking (within 0.5 mile), via a short drive (within 3 miles), or via a longer drive (within 10 miles). Using the open space access...

These three PDFs contain qualitative notes taken during focus group-style interviews in 2017 with coastal resource managers Grand Bay, AL; Port Aransas, TX; and Tampa Bay, FL about their data needs related to tidal wetlands and sea level rise and interest in working with USGS researchers to receive that data. The coastal managers were all engaged in conversations with USGS scientists as part of a separate project entitled Landscape conservation design for enhancing the adaptive capacity of coastal wetlands in the face of sea-level rise and coastal development, regarding tidal wetlands in the Gulf Coast region and the ability of investigators leading that project to provide data suitable for use in various resource...
This data is from a survey of participants in four workshops hosted by USGS researchers in collaboration with The Nature Conservancy (TNC) in communities along the Gulf Coast in 2017. The workshops were part of the Landscape conservation design project, funded separately by the USGS. The current project had no role in identifying or selected coastal managers with whom to speak; that was the responsibility of the Landscape conservation design project and occurred before the involvement of the current project team. These data are particular to the interactions between the Landscape conservation design project team and the particular coastal managers who engaged with their project. The workshops were held in: Milton,...
