Data

The data include measurements of chlorophyll a and algal stoichiometry from benthic algae collected from Sky Pond, Rocky Mountain National Park, Colorado, in 2015-2017; results of nutrient diffusion experiments in Sky Pond including chlorophyll a and other pigments to identify chlorophytes, bacillariophytes, and myxomycetes, and results of a laboratory incubation using benthic...

This dataset contains measured (interval=20 minutes) current velocity during February 1 to April 4, 2018 at seven locations along the Gandy's Beach, New Jersey in upper Delaware Bay. These data were used for the analysis of current pattern dynamics along the coast in upper Delaware Bay with oyster-reef based living shoreline structure for shoreline protection.

These data present geolocated photographs, GPS tracks, and field-mapped ground failures collected during the USGS reconnaissance of ground failures following the 2018 M7.1 Anchorage Earthquake.

This dataset includes fine root productivity data that were estimated via two techniques (serial coring and root in-growth bags) in tidal freshwater wetlands and adjacent oligohaline marshes in coastal South Carolina and Georgia from March 2016 through October 2017.

Fire can be a significant driver of permafrost change in boreal landscapes, altering the availability of soil carbon and nutrients that have important implications for future climate and ecological succession. However, not all landscapes are equally susceptible to fire-induced change. As fire frequency is expected to increase in the high latitudes, methods to understand the vulnerability...

This data release contains predictions of selected fish community metrics and fish species occurrence using Random Forest models with landscape data for inland reaches across the Chesapeake Bay Watershed (CBW). Predictions were made at four time intervals (2001, 2006, 2011, and 2016) according to changes in landcover using the National Land Cover Database (NLCD). The fish sampling data...

The dataset is composed of three data tables containing information from electrofishing and pebble count surveys conducted in tributaries to the Mohawk River in central and eastern New York during 2019 and 2023. 20 sites were surveyed in 2019, and 19 of those same sites were resurveyed in 2023. The first table contains information on the sampled reaches, the second table contains fish...

Fish colonization ability may be one factor affecting population resilience after disturbance. We conducted displacement experiments in headwater streams in Wyoming, U.S.A. to evaluate mottled sculpin (Cottus bairdii) and mountain sucker (Catostomus platyrhynchus) colonization ability. Specifically, we (1) determined if fish could colonize sites rapidly after displacement, (2) evaluated...

Fish survey data for four stream in Tioga County Pennsylvania from 2012-2017. Community data based on 2-3 backpack electrofishing passes with individual lengths and weights.

fishStan is an R package (R Core Team 2020) providing a collection of hierarchical Bayesian models written in the Stan language as called through RStan (Stan Development Team 2020). The package is a USGS software release. The purpose of the package is to document these models for use in USGS projects and allow easy dissemination. The package assumes the user is familiar with R and...

Flea abundance and body condition data for black-tailed prairie dogs on sites treated and not treated with "FipBit" fipronil pellets. We sampled prairie dogs at Conata Basin, Buffalo Gap National Grassland, and Badlands National Park, South Dakota, USA. We sampled fleas from live-trapped prairie dogs during June-October 2018, May-October 2019, and July-August 2020. Prairie dogs were...

A series of 15 digital flood-inundation shapefiles and grids were developed for a 10.2 mile reach of the Pawtuxet River in West Warwick, Warwick, and Cranston, Rhode Island by the U.S. Geological Survey in cooperation with Rhode Island Emergency Management Agency and U.S. Army Corps of Engineers. The coverage of the maps extends from downstream of Natick Pond Dam near State Route 33...
