This collection of files contains independent assessments of both the Tiny tag and camera data, as well as temperature actograms produced by Martin Bulla in his assessment of the Tiny Tag data. Each assessment is saved as a separate file, containing the name of the reviewer in the file name. Note, that .ttd files viewed using Tinytag Explorer may have assessment times that are off by an hour, as the times displayed by Tinytag Explorer are calculated when the data is displayed and depend on the daylight saving settings of the PC at that time. For example, if a .ttd file is opened before and after DST settings change, then all times displayed by Tinytag Explorer will go forward or back. Also, in 2019 camera date and...

This collection of files contains temperature data files (.ttd files) downloaded directly from Tiny Tag devices, as well exported temperature data as .csv files for each nest monitored with Tiny Tags by year. File names include nest ID. .ttd files can be viewed using Tinytag Explorer. Note, however, that the times displayed by Tinytag Explorer are calculated when the data is displayed and depend on the daylight saving settings of the PC at that time. For example, if a .ttd file is opened before and after DST settings change, then all times displayed by Tinytag Explorer will go forward or back. All .csv files were exported using the Tinytag Explorer during the same daylight savings time as when the data were collected....

Many North American shorebird species are experiencing significant population declines, but we have incomplete information about the population sizes and trends for most species. Conservation efforts are underway throughout the Hemisphere to reverse these declines, but we cannot measure the success of those efforts until we have an accurate assessment of population sizes and trends. The Program for Regional and International Shorebird Monitoring (PRISM) is a broad-scale, multi-national effort to monitor both the sizes and trends of shorebird populations (https://www.shorebirdplan.org/science/program-for-regional-and-international-shorebird-monitoring/). PRISM also strives to describe the distribution and habitat...

This file provides data pertaining to bird nests found during surveys on rapid plots and includes information for each nest such as date found, species, location, and egg floatation data. These data do not represent all locations within the Arctic National Wildlife Refuge where specific avian species may be present, as surveys only occurred in discrete survey plots. Additionally, individual birds may have went undetected within survey plots, as detectability was likely less than 100%, and is a function of many variables, including differences in species, habitat, time-of-year, weather conditions, survey effort, and individual surveyor. The data providers have invested considerable effort in QA/QC, but it is possible...
This dataset includes a polygon vector shapefile that provides information pertaining to the sampling universe (i.e., the potential sampling units within the study area) from which rapid surveys were selected. To delineate sampling units (i.e., survey plots), we overlaid the 1002 Area of the Arctic NWR with a grid of 16 ha plots (400 × 400 m each) in ArcGIS 10 (Environmental Systems Research Institute, Redlands, CA, USA; Alaska Albers Equal Area Conic NAD83). Given the logistical constraints for obtaining permission to access private lands within the Arctic NWR, we limited our spatial sampling to public lands administered by the U.S. Fish and Wildlife Service using the National Wildlife Refuge Land Status Data for...
Shallow (300 ft or less) coal exploration drill-hole data from 692 wells located in Arkansas are provided in this data release. The well locations extend over nine Arkansas counties and were drilled between 1975 and 1977, primarily by Phillips Petroleum Company (Phillips). Also included in the dataset are 79 wells drilled by Tenneco. The data were donated to the U.S. Geological Survey (USGS) in 2001 by the North American Coal Corporation, which purchased the Phillips assets as part of a larger dataset. Under the terms of the agreement with North American Coal Corporation, the data were deemed proprietary until February 2011, a period of 10 years after the donation. The Arkansas data contained in this release were...
Model Archive and Results for Unsteady Simulations of Egg and Larval Drift in the Maumee River, Ohio
This page contains results from 304 Fluvial Egg Drift Simulator (FluEgg; version 4.1.1) simulations of invasive carp eggs and larvae in the Maumee River, Ohio, under unsteady flow conditions. FluEgg models the drift and dispersion of eggs and larvae in fluvial environments. The eggs develop, changing in size and density, and eventually hatch into larvae. The simulations end when the larvae reach the gas bladder inflation stage or when the set duration of the simulation is exceeded (whichever comes first). FluEgg requires the user to provide hydraulic data to drive the drift model. The hydraulic inputs for these FluEgg simulations were generated using a one-dimensional unsteady hydraulic model of the Maumee River...

This data release contains time series and plots summarizing mean monthly temperature and total monthly precipitation, runoff, and streamflow from the U.S. Geological Survey Monthly Water Balance Model at 115 National Wildlife Refuges within the U.S. Fish and Wildlife Service Mountain-Prairie Region (CO, KS, MT, NE, ND, SD, UT, and WY). The four variables are derived from two sets of statistically-downscaled general circulation models from 1951 through 2099. The three variables were summarized for comparison across four 19-year periods: historic (1951-1969), baseline (1981-1999), 2050 (2041-2059), and 2080 (2071-2089). For each refuge, mean monthly plots, seasonal box plots, and annual envelope plots were produced...
The Spor Mountain study area is located in the Spor Mountain Range, approximately 42 miles northwest of Delta, Utah. Mining in the Spor Mountain district began in the 1940s and continues to present day. Fluorspar, uranium, and beryllium are the main ores mined(Ege, 2005). From August through September 2013, the United States Geological Survey (USGS) collected a total of 73 samples from abandoned mine wastepiles, channel sediments downslope of wastepiles, and background areas. The samples were sieved to obtain the less than 177 micron fraction. Geochemical analyses were completed through a third-party contract by General Society of Surveillance (SGS) with method ICM40B - Fifty-five major (except Si and Na), rare...

We have dated a boulder field in Zepp, VA using cosmogenic Be-10 exposure dating. Three samples taken from boulders at three elevations in the boulder field (804 m asl, 818 m asl, and 831 m asl) were processed at the Reston Cosmogenic Nuclide (RECON) Lab and measured via accelerator mass spectrometry at the Purdue Rare Isotope Measurement (PRIME) Lab. The results of this work are summarized in the file “Zepp_Exposure_Beryllium10_Odom.csv”. This file contains all relevant sample location data, as well as input variables for exposure age calculations. We employed the CRONUS v.3 exposure age calculator (Balco et al., 2008) to estimate exposure ages for these samples and report exposure ages derived using the LSDn time-dependent...
A goal of the USGS Earth Mapping Resources Initiative (Earth MRI) program, which partners the USGS with State Geological Surveys, Federal agencies, and the private sector, is to collect new geological, geophysical, geochemical, and topographic (lidar) data in key areas of the U.S., with the purpose of stimulating domestic mineral exploration and production of critical minerals. As a first step, the Earth MRI program identified regional geographic areas within the United States that may have potential to host deposits containing critical minerals. These are the focus areas described in Dicken and others (2022) (https://doi.org/10.5066/P9DIZ9N8). As a further step to meet Earth MRI priorities, mineral deposit information...

This dataset includes CSV data files containing environmental data that may be associated with the occurrence and toxicity of the diatom Pseudo nitzschia in Frenchman Bay, Maine, that can form harmful algal blooms and produce the toxin domoic acid. The dataset covers the period 2010 through 2022 or shorter period depending on the variable. Elevated concentrations of domoic acid in Pseudo nitzschia can lead to the contamination of shellfish, threats to human health and closures of shellfish harvesting areas. This dataset was compiled in cooperation with the National Park Service. The file “Site_Infomation_v4.csv” contains the latitudes and longitudes for the locations where Pseudo nitzschia cells were enumerated,...
The roselaari subspecies of Red Knot is one of the rarest shorebird populations breeding in North America, based on a the current population size estimate of 17,000 individuals (Carmona et al 2013). As a result of suspected declines,the roselaari subspecies has been designated as threatened by the Committee on the Status of Endangered Wildlife in Canada and was petitioned for listing under the U.S. Endangered Species Act. The U.S. Fish and Wildlife Service’s decision to not conduct a full status review for listing was based on the lack of substantial information identifying threats and population trends (USFWS 2011). The apparent low population size coupled with the scarcity of information on many demographic and...
