Data

The U.S. Geological Survey (USGS) Data at Risk (DaR) team partnered with the Forest and Rangeland Ecosystem Science Center (FRESC) to preserve and release a subset of their golden eagle telemetry data. In the 1990's, researchers from what is now FRESC worked with Boise State University (BSU) and collected telemetry and ground observation data that documented the local and migratory movements and b

Impacts of dreissenid mussels (Dreissena spp.) on Great Lakes ecosystems are well documented, and a better understanding of mechanisms that cause variation in mussel abundance is needed. An outstanding question is how much mussel biomass is consumed by fish predation. A significant difficulty for investigating mussel consumption by fish is that mussels in stomachs are often a mix of crushed shell

Assessing the distribution and abundance of both predator and prey (forage) fish species is a cornerstone of ecosystem-based fishery management, and supports decision making that considers food-web interactions. In support of binational Great Lakes fishery management the objectives of this survey were to: provide estimates of densities of key forage and predator species in the western basin of Lak

This data release contains mean-annual total nitrogen (TN) loads predicted by a SPARROW model for individual stream and shoreline reaches in the Chesapeake watershed as defined by NHDPlus, a 1:100,000 scale representation of stream hydrography built upon the National Hydrography Dataset (NHD) (Horizon Systems, 2010). Also included are the input variables required to execute the model, including la

This data release consists of information from published tables in Connecticut Water Resources Bulletins (WRBs) transcribed into tabular digital format. Information about wells and test holes in the WRBs used in this data release consists of geographic location, depth to consolidated rock (bedrock depth), and depth of the well or test hole. The WRBs, published between 1966 and 1980 by the U.S. Geo

The U.S. Geological Survey (USGS) 3D Elevation Program (3DEP) has started to initiate the development of pilot 3D National Topography Models to generate 3-dimensional surface elevation models that integrate river topographic bare-earth elevation surfaces with channel bed bathymetry. Detailed knowledge of integrated river system topography, bathymetry, and topobathymetry, is essential for habitat r

This data release contains input data used in model development and TIF raster files used to predict the probability of low dissolved oxygen (DO) and high dissolved iron (Fe) in groundwater within the glacial aquifer system in the northern continental United States. Input data include measured DO and Fe concentrations at groundwater wells, and associated predictor variable data. The probability of

This data release includes metadata and tabular data that document the responses of koa moths and other insects to changes in habitat conditions before and after koa (Acacia koa) defoliation by koa moth caterpillars (Scotorythra paludicola) at Hakalau Forest National Wildlife Refuge during 2013-2014. Data sets document changes in (1) koa moth abundance, (2) koa moth caterpillar abundance, (3) koa

This data set is comprised of one table with sampling information and NCBI BioProject accession numbers for sequence information of this amplicon-based study targeting Labyrinthula, Phytophthora, and Halophytophthora of known pathogenic and non-pathogenic [to eelgrass (Zostera marina)] strains from eDNA samples. eDNA samples included water, sediment, and eelgrass from Notsuke Wan (Cove) Japan, Saf

The Edwards aquifer in south-central Texas is one of the most permeable and productive aquifers in the United States and is the major source of public water supply for Bexar, Comal, Hays, Medina, and Uvalde Counties. The Edwards aquifer also supplies large quantities of water to agriculture, business, and industry in the region. The major artesian springs of the Edwards aquifer provide water for r

This data release includes zooplankton data collected with a 64-micron mesh net from 9 transects in Lake Huron between April and August 2017. At each transect, data were collected at up to three sites, ranging in bottom depths from 18 to 82 m. The volume sampled at each site was estimated with a flowmeter. Micro- and macro- crustaceans were identified, enumerated, and measured using a dissecting o
