USGS Lake Erie East Harbor bottom trawl data series, 1961-2011 (ver. 2.0, March 2020) USGS Lake Erie East Harbor bottom trawl data series, 1961-2011 (ver. 2.0, March 2020)
The USGS Lake Erie Biological Station?s East Harbor sampling program began in 1961 with the commissioning of the research vessel Musky II. It is the longest known continuous trawl survey in Lake Erie. In addition to spanning over 50 years, the data series is unique for three prominent design elements: 1) sampling was conducted at three depth strata; 2) replicate trawl samples were...
High forb diversity prairie reconstruction at Neal Smith NWR 2005-2015 High forb diversity prairie reconstruction at Neal Smith NWR 2005-2015
This data set consists of data collected during 2005-2007, 2010, and 2015 at Neal Smith National Wildlife Refuge in Iowa, USA that were used in the analysis in support of the article titled "Toward improving pollinator habitat: Reconstructing prairies with high forb diversity," which has been submitted to Natural Areas Journal. We compared pollinator habitat, in terms of planted forb...
Water Velocity Magnitude and Direction Collected on May 8-9, 2019 at Select Breakwaters in Lake Erie at Presque Isle State Park, Erie, PA Water Velocity Magnitude and Direction Collected on May 8-9, 2019 at Select Breakwaters in Lake Erie at Presque Isle State Park, Erie, PA
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...
Data on well characteristics and well-pair characteristics for estimating high groundwater levels in selected areas of Massachusetts Data on well characteristics and well-pair characteristics for estimating high groundwater levels in selected areas of Massachusetts
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.

utc2nwislocal, UTC date-times to NWIS local time zones using UTC offsets utc2nwislocal, UTC date-times to NWIS local time zones using UTC offsets
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...
Physiological Ecology of Brown Pelican in the Gulf of Mexico, 2013-2016 Physiological Ecology of Brown Pelican in the Gulf of Mexico, 2013-2016
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.

Data tables summarizing the source-specific estimated water withdrawals in Florida by category, county, and water management district, 2015. Data tables summarizing the source-specific estimated water withdrawals in Florida by category, county, and water management district, 2015.
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...
Arctic Shorebird Population Model Arctic Shorebird Population Model
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.

Marginalizing Bayesian population models - data for examples in the Grand Canyon region, southeastern Arizona, western Oregon USA - 1990-2015 Marginalizing Bayesian population models - data for examples in the Grand Canyon region, southeastern Arizona, western Oregon USA - 1990-2015
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...
