Population Structure and Genetic Diversity of Eastern North American Moose

Hair samples were collected in discrete areas during radio-collar studies in Vermont under the auspices of University of Vermont IACUC protocol #17-035 (n=106), New Hampshire (n=34), and Maine (n=57). Hair and tissue samples were opportunistically collected from animals that were harvested, died in vehicle collisions, or translocated throughout Vermont (n = 105), Quebec (n = 198), Massachusetts (n

South White Lake Shoreline Protection (ME-22): 2005 and 2018 land-water classifications

The Louisiana State Legislature created the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed pursuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to arresting

MODFLOW-NWT model to simulate the groundwater flow system near Puget Sound, Pierce and King Counties, Washington

A three-dimensional groundwater flow model, constructed in MODFLOW-NWT, was developed to evaluate the groundwater flow system near Puget Sound, Pierce and King Counties, Washington. A steady-state model version was constructed to simulate equilibrium conditions, while a transient model version was constructed to simulate monthly variability from January 2005 to December 2015. The model was used to

Keswick Reservoir, California, Delft3D-FM Model Archive

Application of Delft3D-FM model to Keswick Reservoir in California, for short-term (days) simulations. Model archive includes source code (open-source, created by Deltares in the Netherlands), input files, and output files in netCDF format. Source code will need to be compiled for the operating system and hardware being used. Instructions are included with the source code. A separate data release

Alkenone temperature estimates from the Miocene (Burdigalian, Langhian, Tortonian) and Pliocene (Zanclean) Atlantic Coastal Plain sediments

This dataset collects sea surface temperature data generated through alkenone analysis of Neogene sediments collected from cores and outcrops of the Virginia and Maryland Atlantic Coastal Plain.

Survival, growth, and chemical data from a study on influences of water hardness on chronic toxicity of potassium chloride to a Unionid mussel (Lampsilis siliquoidea)

The objective of this study was to evaluate the chronic toxicity of potassium  (tested as KCl) to a commonly tested unionid mussel (fatmucket, Lampsilis siliquoidea) at five water hardness levels (25, 50, 100, 200, 300 mg/L as CaCO3) representing most surface waters in the United States. Chronic 28-d potassium chloride toxicity tests were conducted with 3-week-old juvenile fatmucket using six conc

Occurrence data of the western bumble bee from 1998 to 2020 across the western United States

These raw survey data and associated explanatory covariates were used to model western bumble bee occupancy across the western conterminous United States from 1998 to 2020. These data underlie the analyses found in the publication of “Recent and future declines of a historically widespread pollinator linked to climate, land cover, and pesticides” by Janousek et al. 2023 in the Proceedings of the N

Native Species Response to 100 HP boat motor acoustic stimulus

This dataset includes the behavioral fish data needed to assess the responses of Upper Mississippi River fishes to an acoustic stimulus (i.e., playback of a 100 hp boat motor). Native ostariophysians (bigmouth buffalo Ictiobus cyprinellus, channel catfish Ictalurus punctatus, and fathead minnow Pimephales promelas), invasive ostariophysians (bighead carp Hypophthalmichthys nobilis, common carp Cyp

Bathymetry, Point Clouds, and Water Velocity in the Downstream Approach to Peoria Lock, near Peoria, Illinois, During Testing of an Automated Barge Clearing Deterrent, July–September 2022

A variety of new technologies are being evaluated to mitigate the spread of invasive carps from the Illinois River to the Great Lakes. In 2022, the U.S. Army Corps of Engineers, U.S. Fish and Wildlife Service, and U.S. Geological Survey undertook a field-scale interagency study to determine the efficacy of an Automated Barge Clearing Deterrent (ABCD) in flushing live fish away from commercial barg

Powerline Corridors in the Western United States and Canada

Powerlines in the western United States and Canada as identified by the 22 source data layers used to compile this shapefile. Source data were collected by personal contact or through the internet in the winter and spring of 2004 and assimilated using ArcGIS. This file is a complete record of overhead powerline data that was available as of 5/15/2004 but IS NOT INTENDED TO BE A COMPLETE REPRESENTA

Tabular geochronologic and geochemical data from metasedimentary and associated rocks in the Lane Mountain area, San Bernardino County, California

This dataset provides geochronologic and geochemical data for selected metasedimentary and associated rock samples collected in the Lane Mountain area about 20 kilometers northwest of Barstow, California. Geochronologic data were obtained for 24 samples, and geochemical data were obtained for 5 of these. The dataset consists of four tables in csv (comma separated values) format: (1) sample localit

Total phosphorus loads estimated from tributaries and direct drainages to the Great Lakes during 2012-2018 using the model load ratio approach and the unit area load approach

In this data release, we provide the data used to compute total annual phosphorus loads from tributaries and direct drainages to the Great Lakes during 2012-18 using the model load ratio approach and the unit area load approach and the resulting annual loads for 2012–18. This data release consists of: (1) measured loads at 24 sites, computed using the surrogate regression approach (Robertson et al
