The USGS Forecasting Scenarios of Land-use Change (FORE-SCE) model was used to produce an agricultural biofuel scenarios for the Northern Glaciated Plains, from 2012 to 2030. The modeling used parcel data from the USDA's Common Land Unit (CLU) data set to represent real, contiguous ownership and land management units. A Monte Carlo approach was used to create 50 unique replicates of potential landscape conditions in the future, based on a agricultural scenario from the U.S. Department of Energy's Billion Ton Update. The data are spatially explicit, covering the entire Northern Glaciated Plains ecoregions (an EPA Level III ecoregion), with a spatial resolution of 30-meters and 22 unique land-cover classes (including...

New land-bathymetry and land-lake surface elevation models were produced for the Lake Superior region. The models combine Shuttle Radar Topography Mission (SRTM) topography data with lake surface elevation and bathymetry data sets for Lakes Superior, Michigan, and Huron. The SRTM data set was chosen because it spans the international border and has relatively high resolution at 30 m cell size. These data were subsequently used for aeromagnetic data processing and gravity data reduction.

River bathymetry and stream velocity measurements were collected in March 2015 along the upper Willamette River, Oregon, between Eugene and Corvallis. These surveys were collected over a small range of discharges using a real time kinematic global positioning system (RTK-GPS) and acoustic Doppler current profiler (ADCP) on a motorboat while transecting at various cross sections along the river. These datasets were collected for equipment calibration and validation for the National Aeronautics and Space Administration’s (NASA) Surface Water and Ocean Topography (SWOT) satellite mission. This is one of multiple survey datasets that will be released for this effort.

In this dataset we present two maps that estimate the location and population served by domestic wells in the contiguous United States. The first methodology, called the “Block Group Method” or BGM, builds upon the original block-group data from the 1990 census (the last time the U.S. Census queried the population regarding their source of water) by incorporating higher resolution census block data. The second methodology, called the “Road-Enhanced Method” or REM, refines the locations by using a buffer expansion and shrinkage technique along roadways to define areas where domestic wells exist. The fundamental assumption with this method is that houses (and therefore domestic wells) are located near a named road....

Note: this data release has been deprecated. Please see new data release here: https://doi.org/10.5066/P18WWMVR. Freshwater fish are among the most vulnerable taxa to climate change globally but are generally understudied in tropical island ecosystems. Climate change is predicted to alter the intensity, frequency, and variability of extreme flow events on the Caribbean island of Puerto Rico. These changes may impact Caribbean native and non-native stream ecosystems and biota complex ways. We compiled an extensive dataset of native and non-native fish assemblages collected at 119 sites across Puerto Rico from 2005 to 2015. We coupled these data with stream flow indices and dam height to understand how flow dynamics...

In 2012, the U.S. Geological Survey (USGS) in cooperation with Colorado Springs Utilities selected 10 reaches or study areas along Fountain Creek between Colorado Springs and the confluence of Fountain Creek at the Arkansas River for annual bed and bank characterization and topographic surveys. The 10 selected study areas are approximately 5 to 20 bank-full channel widths in length. The topographic surveys collected point data of location and elevation in the active channel and along both left and right banks and flood plains. Starting in 2012, USGS personnel have collected topographic survey data annually during the winter, spring, or summer using real-time kinematic Global Navigation Satellite Systems. These point...

This data set provides a table of length, weight, sex, and estimated fecundity of Silver Chub Macrhybopsis storeriana in western Lake Erie from 1979 through 1987. These data are potentially useful to those studying recovery and restoration of Silver Chub in Lake Erie. These data were collected as part of routine trawl surveys in western Lake Erie. Other data associated with these data can be found in the Great Lakes Research Vessel Operations 1958-2018. (ver. 3.0, April 2019). A drawn map, originally packaged alongside the hard copy data sheets, is included in this data release. This map guides users in identifying specific locations of capture. Due to the legacy nature of these data, location data is estimated...
The alluvial aquifer of the Mississippi embayment lies within a syncline plunging south towards the Gulf of Mexico with the axis of the syncline roughly following the Mississippi River (Cushing and others, 1964, Hart and others, 2008). The trough of the syncline is comprised of alluvial and terrace deposits of Quaternary age (Ackerman, 1996). A potentiometric-surface map of the Mississippi River Valley alluvial aquifer represents the altitude at which water would stand in tightly cased wells completed at any location within the study area (Schrader, 2015). Using the altitude of water levels measured in the study area, the potentiometric-surface map depicts points of equal altitude with contours denoting a given...

Fish occurrence data to support high-resolution distribution models and test various community and macroecological hypotheses have not been available at the national scale. We present IchthyMaps, a database of high-quality historical fish occurrences covering fishes of the conterminous United States. Designed on the principles of metacommunity ecology, IchthyMaps is a compilation of presence records from atlases up to 1990, at the resolution of the 1:100,000 National Hydrography Database Plus (NHDPlus) inter-confluence stream segment, readily aggregated into hierarchically coarser units (e.g. hydrologic unit code 8-digit and 12-digit watersheds). IchthyMaps contains about 606,550 presence records for 1,038 species...

Examination of food webs and trophic niches provide insight into organisms’ functional ecology, yet few studies have examined the trophodynamics within submarine canyons, where the interaction of morphology and oceanography influences food deposition. Stable isotope analysis and Bayesian ellipses documented deep-sea food web structure and trophic niches in Baltimore Canyon and the adjacent open slopes in the U.S. Mid-Atlantic Region. Results revealed isotopically diverse feeding groups, comprising approximately 5 trophic levels. Regression analysis indicated that consumer isotope data are structured by site (canyon vs. slope), feeding group, and depth. Benthic feeders were enriched in 13C and 15N relative to suspension...
