Grain-Size Data from Upper Florida Keys: Crocker Reef, FL Grain-Size Data from Upper Florida Keys: Crocker Reef, FL
Sediment samples were collected from undisturbed sections of the seafloor around Crocker Reef, Florida which is a senile, degrading barrier reef located in the northern portion of the Florida Reef Tract (Figure 1). Samples were collected from November 2017 to April 2019. The sediment sample locations were near instruments deployed during the same period to record time series of ocean...
Aerial Imagery of the North Carolina Coast: 2019-11-26 Aerial Imagery of the North Carolina Coast: 2019-11-26
The U.S. Geological Survey (USGS) Remote Sensing Coastal Change (RSCC) project collects aerial imagery along coastal swaths, in response to storm events, with optimized endlap/sidelap and precise position information to create high-resolution orthomosaics, three-dimensional (3D) point clouds, and digital elevation/surface models (DEMs/DSMs) using Structure-from-Motion (SfM)...
MODFLOW-USG model used to evaluate water management issues in the Los Angeles Coastal Plain, California MODFLOW-USG model used to evaluate water management issues in the Los Angeles Coastal Plain, California
Seven model data sets are archived for this groundwater study. One simulation for the Los Angeles Coastal Plain groundwater model and six scenario simulations to evaluate the effects of future production well rate increases to reach maximum adjudicated rates and construction of new well fields. Simulations were run with MODFLOW-USG.
Spatial Database of Known and Potential Cienegas in the Greater Madrean Archipelago Ecoregion Spatial Database of Known and Potential Cienegas in the Greater Madrean Archipelago Ecoregion
This dataset provides location information and some limited attributes of known and potential cienegas in the Madrean Archipelago ecoregion and closely surrounding area. This was created using point data and information provided by Dean Hendrickson and Thomas Minckley, combined with potential locations derived from analysis of classified raster land cover images and other specialized...
Codebook vectors and predicted rare earth potential from a trained emergent self-organizing map displaying multivariate topology of geochemical and reservoir temperature data from produced and geothermal waters of the United States Codebook vectors and predicted rare earth potential from a trained emergent self-organizing map displaying multivariate topology of geochemical and reservoir temperature data from produced and geothermal waters of the United States
This data release consists of three products relating to a 82 x 50 neuron Emergent Self-Organizing Map (ESOM), which describes the multivariate topology of reservoir temperature and geochemical data for 190 samples of produced and geothermal waters from across the United States. Variables included in the ESOM are coordinates derived from reservoir temperature and concentration of Sc, Nd...

This data matrix contains the codebook vectors for a 82 x 50 neuron Emergent Self-Organizing Map which describes the multivariate topology of reservoir temperature and geochemical data for 190 samples of produced and geothermal waters from across the United States. Variables included are coordinates derived from reservoir temperature and concentration of Sc, Nd, Pr, Tb, Lu, Gd, Tm, Ce...
Chemical and isotopic composition of produced waters from the lower Eagle Ford Group, south-central Texas Chemical and isotopic composition of produced waters from the lower Eagle Ford Group, south-central Texas
This dataset contains chemical and isotopic data from 39 produced water samples collected from sealed separators containing water from horizontal hydrocarbon wells in the lower Eagle Ford Group. The samples were collected from Lavaca and Gonzales counties, Texas in December, 2015. All wells had been in production for longer than 6 months and had produced more than 10,000 barrels (~160...
Bird Species Checklists from USGS Alaska Science Center Field Camps Bird Species Checklists from USGS Alaska Science Center Field Camps
These data are daily summary checklists of all bird species observed at U.S. Geological Survey, Alaska Science Center (ASC) field camps. Data include species observation details such as observers, dates, location, and number of individuals seen.
Compiled Input Data and Glacier-Wide Mass Balances Compiled Input Data and Glacier-Wide Mass Balances
This data release includes compiled input data and glacier-wide mass balance data collected on various North American glaciers under various projects and funding sources. Vocabulary used is defined herein and follows Cogley and others (2011) Glossary of Glacier Mass Balance. Input data are of three types: 1) time-variable area altitude distribution (AAD); 2) time series of point mass...
Glacier-Wide Mass Balance and Compiled Data Inputs: Juneau Icefield Glaciers Glacier-Wide Mass Balance and Compiled Data Inputs: Juneau Icefield Glaciers
This data release includes glacier wide mass balance solutions for Taku and Lemon Creek Glaciers, as well as the refined inputs used in these calculations. Input data are of three types: 1) time-variable area altitude distribution (AAD); 2) time series of point water balance at long term sites (with secondary sites given in recent years); 3) weather data from nearby stations, either...
Documentation of VS2DH Seepage Models: Surface Infiltration and Unsaturated Zone Characterization in Support of Managed Aquifer Recharge, Washoe County, Nevada Documentation of VS2DH Seepage Models: Surface Infiltration and Unsaturated Zone Characterization in Support of Managed Aquifer Recharge, Washoe County, Nevada
Two-dimensional variably saturated heat and flow models (VS2DH) were used to examine seepage rates along the Birdspring drainage for the purpose of exploring the drainage channel for use in an managed aquifer recharge project. Six transect models were separately calibrated to sediment temperatures observed during episodic runoff events during water year 2017 and 2018. The models were...
Long-distance movements of non-migratory golden eagles in western North America, 2007-2017 Long-distance movements of non-migratory golden eagles in western North America, 2007-2017
We studied >500 golden eagles tracked by telemetry over a 10-year period in western North America, of which 160 engaged in non-routine, long-distance (> 300 km) movements. We identified spatial and temporal correlates of those movements at both small and large scales, and we quantified movement timing and direction. We further tested which age and sex classes of eagles were more likely...
