Background: Presque Isle State Park (PISP), located in northwestern Pennsylvania, is located on a 3,127 acre peninsula that extends into Lake Erie. Approximately 7 miles long, PISP is a recurving sand spit where the width of the neck is less than 1,000 feet and the center, eastern end exceeds 1 mile. The park boundary extends 500 feet offshore around the perimeter of the peninsula. The...

A method to estimate the probable high groundwater level in Massachusetts, excluding Cape Cod and the Islands was developed in 1981. The method, commonly called the "Frimpter Method," uses a groundwater measurement from a test site, groundwater measurements from an index well, and a distribution of high groundwater levels from wells in similar geologic and topographic settings.

The utc2nwislocal package in the R language provides a light-weight, dependency-free utility for converting Coordinated Universal Time (UTC) base::as.POSIXct() date-time values into character-string representations for time zones. The UTC offsets for individual time zones are determined from the time-zone codes recognized by the U.S. Geological Survey National Water Information System...

The datasets stored in this folder summarize health data for Brown Pelican nestlings and breeding adults from 2013-2016 in the Northern Gulf of Mexico at 9 breeding colonies from Texas to the Florida Panhandle. Data include values of blood analyte, and concentration of polycyclic aromatic hydrocarbons in blood and feather samples.

The model input and output of topography and bathymetry values resulting from forecast simulations of coupled modeling scenarios occurring between 2015 and 2025 at Dauphin Island, Alabama, and described in U.S. Geological Survey (USGS) Open-File Report 2020-1001 (https://doi.org/10.3133/ofr20201001), are provided here. For further information regarding model input generation and...

The model input and output of bathymetry and topography elevations resulting from a deterministic simulation from 2004 to 2015 at Dauphin Island, Alabama, as described in Mickey and others (2020), are provided here. For further information regarding model input generation and visualization of model output topography and bathymetry refer to Mickey and others (2020). For more information...

In 2015, the total amount of water withdrawn in Florida was estimated at 15,319 million gallons per day (Mgal/d). This includes 9,598 Mgal/d of saline water and 5,721 Mgal/d of fresh water. Groundwater accounted for 3,604 Mgal/d and surface water accounted for 2,117 Mgal/d of the fresh water withdrawals. Surface water accounted for 9,400 Mgal/d and groundwater 198 Mgal/d of the saline...

This R script will run one example of the stochastic matrix models run by Weiser et al. (2020) to simulate shorebird populations. The model predicts population growth rates and elasticity values of vital rates. The example script is stand-alone and contains input values for one example species; input values for the other species are provided in the manuscript.

This data release includes 2 child items with tracking data for Black Scoters, a sea duck species that breeds throughout higher latitudes of Alaska and Canada and winters along coastal areas of North America. Child Item 1: "Argos Satellite Tracking Data for Black Scoters (Melanitta americana) - Processed Data" -- Quality-controlled data collected from Argos satellite transmitters.

These data were compiled here to fit various versions of Bayesian population models and compare their performance, primarily the time required to make inferences using different softwares and versions of code. The humpback chub data were collected by US Geological Survey and US Fish and Wildlife service in the Colorado and Little Colorado Rivers from April 2009 to October 2017. Adult...

These data were compiled for research pertaining to the effects of stand density on growth rates in semi-arid forests. Increasing heat and aridity in coming decades is expected to negatively impact tree growth and threaten forest sustainability in dry areas. Maintaining low stand density has the potential to mitigate the negative effects of increasingly severe droughts by minimizing...

These data were compiled for a comprehensive review of pinyon-juniper communities including Pinus edulis, Pinus monophylla, Juniperus osteosperma, Juniperus monosperma, and Juniperus scopulorum. Compiled are a list of references cataloged by the topic of interest resulting from the literature search. The characterization for each reference includes the focal species, descriptions of the...
