Data

Standard Fortran provides limited data type, function, and subroutine support leaving the developer to write custom code for every project. This has lead to every developer having their own internal, homemade, Fortran library for doing common operations. In recognition of this, most newer programming languages incorporate a large set of standard data types and functions that the...

Comprehensive list of carcasses detected at Haul Trail in Bayou Sauvage National Wildlife Refuge (Orleans Parish, LA) and relevant findings for specimens subject to postmortem examination at the USGS National Wildlife Health Center (Madison, WI).

This dataset represents elevation data of the beach topography and near-shore bathymetry of Lake Superior at two locations along Minnesota Point, Duluth, Minnesota. LiDAR data were collected using a Velodyne VLP-16 unit representing the beach topography, and multibeam sonar data were collected using a Norbit integrated Wide Band Multibeam System compact (iWBMSc) sonar for bathymetry. The...

Repeat surveys of beach topography and nearshore bathymetry were performed by a team of scientists from the U.S. Geological Survey, Washington State Department of Ecology, and Oregon State University in the Columbia River littoral cell (CRLC), Washington and Oregon. Bathymetric and topographic data were collected along a series of shore-perpendicular survey lines spaced at 100- to 1,000...

Bedload and ancillary data herein were used to calculate and compare the bedload-trapping efficiencies of four types of pressure-difference bedload samplers as part of episodic, sediment-recirculating flume tests. The U.S. Geological Survey, in concert with the Federal Interagency Sedimentation Project (FISP), conducted the tests from January through March 2006 at the St. Anthony Falls...

We investigated the behavioral response of female Pacific lamprey to three odors and to differences in water flow. Adult lamprey were challenged with: 1) washings from conspecifics, 2) with washings from adult males, and 3) with an artificial odor that mimicked a component of a natural lamprey pheromone. In addition, we conducted parallel tests to check for rheotaxis. The fish were...

The Bonnet Carré Spillway (BCS), located about 28 miles northwest of New Orleans, was constructed by the US Army Corp of Engineers in the early 1930s as part of an integrated flood-control system for the lower Mississippi River (MR). The BCS control structure consists of 350 individual bays that can be opened to divert water from the river to Lake Pontchartrain to relieve pressure on...

San Francisco Bay and Estuary is largely urbanized and developed, and the southern bay is the most urbanized with many sources of nutrients, many concerns that the system might become eutrophic, and many questions about how South Bay has maintained its relatively good health. The hypotheses for why South Bay is not eutrophic, where other bays have not been so fortunate, include high...

These benthic macroinvertebrate data and associated site characteristics were compiled for the purpose of exploring any relationships between large dams in the Colorado River Basin, their flow management and geographical context, and their associated downstream benthic macroinvertebrate communities. The goal of the analyses based upon these data was to understand how dam conditions...

This data set contains a single table of descriptions of benthic samples collected in 1998 at Nelson and Izembek lagoons, Alaska. This includes: the weight of the sample, the species or species group of benthic animals (also vegetation) and their number, size and weight, and the amount of sand and gravel. These data provide a basis for additional studies that includes sampling of the...

The Best Management Practices Statistical Estimator (BMPSE) was developed by the U.S. Geological Survey (USGS), in cooperation with the Federal Highway Administration (FHWA) Office of Project Delivery and Environmental Review to provide planning-level information about the performance of structural best management practices for decision makers, planners, and highway engineers to assess...

The Risk of Contact Tool (RoCT) is an R-based implementation of the Risk of Contact model described in O'Brien et al. (2014). It uses a variety of spatial inputs (including telemetry point data, a core herd home range (CHHR) polygon, a habitat raster model, and a set of active domestic sheep allotments) together with estimates of bighorn sheep foray behavior to estimate the probability...
