Fecundity data for midcontinent sandhill cranes, 2003-2006 Fecundity data for midcontinent sandhill cranes, 2003-2006
Midcontinent sandhill cranes (Antigone canadensis) are the most abundant management population of cranes in the world and have a broad breeding range. Four breeding segments of midcontinent sandhill cranes have been designated based on spatial and temporal distributions throughout the year, including Western Alaska-Siberia (WA-S), Northern Canada-Nunavut (NC-N), West-central Canada...

This data release includes 2 child items with tracking data for Tundra Swans, a species that nests in coastal areas throughout Alaska and winters across a broad area of North America from the Pacific to Atlantic coasts. Child Item 1: "Argos Satellite Tracking Data for Tundra Swans (Cygnus columbianus) - Processed Data" -- Quality-controlled data collected from Argos satellite...
Velocity, Discharge, and Dye Concentrations During a Dye Tracer Study on the Lower Sandusky River, Ohio, July 11-13, 2017 Velocity, Discharge, and Dye Concentrations During a Dye Tracer Study on the Lower Sandusky River, Ohio, July 11-13, 2017
A dye tracer study was completed on the lower Sandusky River between July 11-13, 2017, during a confirmed Grass carp (Ctenopharyngodon idella) spawning event. The data contained in this data release include time series of dye concentration at fixed stations downstream of the injection site and three-dimensional water-velocity data and discharge measurements collected using acoustic...
SUPERSEDED: Data Associated with Algal Toxin Testing of Common Murres (Uria aalge) and Forage Fish in Alaska, 2015–2017 SUPERSEDED: Data Associated with Algal Toxin Testing of Common Murres (Uria aalge) and Forage Fish in Alaska, 2015–2017
This data release has been SUPERSEDED. No data are provided here. Data from HABs sampling data releases have been appended to U.S. Geological Survey data release: https://doi.org/10.5066/P9MLNP9H. This data set is comprised of two tables with results of algal toxin screening for saxitoxin and domoic acid. We used enzyme-linked immunosorbent assay (ELISA) and high-performance liquid...
Concentrations of Pharmaceutical Contaminants and Their Predicted Effects from a Multi-Regional Assessment of Wadeable USA Streams, 2014-2017 Concentrations of Pharmaceutical Contaminants and Their Predicted Effects from a Multi-Regional Assessment of Wadeable USA Streams, 2014-2017
Human-use pharmaceutical compounds were analyzed at the U.S. Geological Survey, National Water Quality Laboratory, Denver, Colorado, in wadeable streams in 4 Regional Stream Quality Assessments: Northeast (NESQA), Southeast (SESQA), Pacific Northwest (PNSQA) and California (CSQA). Multiple (with few exceptions) samplings occurred at each site, during base flow, between 2014 and 2017...
