Data Releases

The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Surface time for sea turtles in the Gulf of Mexico, 2010-2019

This dataset contains surface dive times, defined as 0-2 m in the water column, for three species of sea turtles (Kemp's ridleys, loggerheads, and green turtles) tracked via satellite telemetry in the Gulf of Mexico during periods within 2010-2019. It contains information on turtle species, location, proportion of time in "surface" bins, region of the Gulf of Mexico, corresponding remotely-sensed

Surveyed coordinates and elevations in a 2017 resurvey of previously established cross sections on the Little Snake and Yampa rivers in Lily and Deerlodge parks, Colorado

These data were compiled for the National Park Service and Upper Colorado River Endangered Fish Recovery Program. Objective(s) of our study were to resurvey previously established cross sections on the Yampa and Little Snake rivers in the Deerlodge Park area to document changes in channel width, depth, and cross-sectional area. A secondary purpose of this study was to document the location of the

Carex specuicola genomic data for the southern Colorado Plateau Desert

These data were compiled to investigate the demographic and phylogeographic of Carex specuicola. Objectives of our study were to understand the demographic and dispersal history of Carex specuicola across hanging gardens, the hybridization history between Carex specuicola and Carex utahensis, and the population structure of Carex specuicola across its distribution. The data release consists of thr

Genetic structure of American black bear populations in the American Southwest and northern Mexico, 1994-2014

Microsatellite genotypes for American black bears collected by Gould et al. 2002 and used to assess the genetic structure of American black bear populations in the American Southwest and northern Mexico. Genotypes are for Ursus americanus individuals.

Predator Movements and Duck Nests in Relation to Habitat Features in Suisun Marsh, CA (2016-2019)

This dataset describes mesopredator locations (raccoons and striped skunks), dabbling duck nest locations (mallard, gadwall, and cinnamon teal), northern harrier nest locations, and random locations in relation to a set of habitat features in Suisun Marsh, California during 2016 through 2019. We designed a series of questions to link fine-scale predator movements and vulnerability of dabbling duck

Data Release for Distribution of Niclosamide Following Granular Bayluscide Applications in Lotic Systems

The granular formulation of Bayluscide [Bayluscide 3.2% Granular Sea Lamprey Larvicide, granular Bayluscide (gB)] is applied in lentic and lotic systems to survey (assessment) and kill (treatment) larval sea lampreys (Petromyzon marinus) in the Great Lakes basin. Granules are spread on the water surface, settle to the sediment surface, and dissolve. The potential risk of niclosamide exposure [5 Ch

Application of a Decision Support Tool for Prioritizing Restoration of Private Land Units within a Joint Northern Missouri Focal Area - derived spatial data

This shapefile describes the outputs from the application of a decision support tool (Rohweder and others 2015) used to assist the Northern Missouri Private Lands Program make thoughtful and strategic choices about where to spend its limited management resources. It incorporates landscape and management unit features to help prioritize management on 17 oak savanna and open woodland restoration and

Behavioral and Reproductive Effects of the Lampricides TFM and TFM:1% Niclosamide on Native Freshwater Mussels - Data Release

This study continues our investigations into the effects of lampricides on mussels by extending research into potential effects on behavioral and reproductive endpoints on the plain pocketbook mussel(Lampsilis cardium). We hypothesized that TFM (3-trifluoromethyl-4'-nitrophenol) and TFM with Niclosamide (NIC, 2', 5-dichloro-4'-nitrosalicylanilide, hereafter TFM:NIC) would reduce the viability of f

Application of a Decision Support Tool for Prioritizing Management Units at Minnesota Valley Wetland Management District - derived spatial data

This shapefile describes the outputs from the application of a decision support tool (Rohweder and others 2015) used to assist the Minnesota Valley Wetland Management District make thoughtful and strategic choices about where to spend its limited management resources. It incorporates landscape and management unit features to identify which Waterfowl Production Areas have the greatest biological po

Survival and viral load of chinook salmon, sockeye salmon, and steelhead trout exposed to 4 genogroups of infectious hematopoietic necrosis virus (IHNV)

Theory of the evolution of pathogen specialization suggests that a specialist pathogen gains high fitness in one host, but this comes with fitness loss in other hosts. By contrast, a generalist pathogen does not achieve high fitness in any host, but gains ecological fitness by exploiting different hosts, and has higher fitness than specialists in non-specialized hosts. As a result, specialist path

Calibrated marine sparker source amplitude decay versus offset offshore Santa Cruz, California

This two-vessel survey was designed to quantify the decay of sound emitted from the SIG ELP790 minisparker (powered at 700 joules) and from the Applied Acoustics Delta Sparker (powered at 1.0 and 2.4 kilojoules) as a function of distance during marine geophysical surveys. Seven transect sites were surveyed at five different water depths (25, 50, 100, 200, and 600 meters) to compare the effects of

High-resolution seismic data acquired at northern Ano Nuevo, California

The U.S. Geological Survey acquired high-resolution P- and S-wave seismic data across the Frijoles Fault strand of the San Gregorio Fault Zone (SGFZ) at northern Ano Nuevo, California in 2012. SGFZ is a right-lateral fault system that is mainly offshore, and prior studies provide highly variable slip estimates, which indicates uncertainty about the seismic hazard it poses. Therefore, the primary g
