Exposure-related effects of Zequanox on juvenile lake sturgeon (Acipenser fulvescens) and lake trout (Salvelinus namaycush) Data

The environmental fate, persistence, and point-source discharge of traditional molluscicidal compounds led to the development of an alternative biomolluscicide, Zequanox. Previous studies evaluated the efficacy and non-target animal safety of Zequanox in laboratory, mesocosm, and field enclosure studies. One study indicated sensitivity of salmonid species and lake sturgeon (Acipenser fulvescens Ra

Conservation easements in the Prairie Pothole Region of North Dakota: characteristics of wetland catchments and key factors for determination of drainage setback distances

This data release includes characteristics of wetland catchments associated with U.S. Fish and Wildlife conservation easement lands located in the Prairie Pothole Region of North Dakota. Characteristics include wetland catchment areas, slope length, land use, soil mapping unit, and slope grades of representative soils. County and ecoregion also are included. Summary data pertaining to lateral setb

Soil flux (CO2, CH4), soil temperature, and soil moisture measurements at the Great Dismal Swamp National Wildlife Refuge (2015 - 2017)

Data were obtained to assess how forest type, hydrologic conditions and management strategies affect GHG soil flux at the Great Dismal Swamp National Wildlife Refuge. The goal is to relate changes in GHG fluxes to shifts in refuge hydrologic management on forested peatlands. We identified nine study site locations, representing three mature vegetation communities [Atlantic White Cedar (desired com

Sediment Data for Samples Collected in 2015, 2016, and 2017 from Coastal Louisiana

This data release serves as an archive of sediment data collected in 2015, 2016, and 2017 from coastal Louisiana. In 2015 and 2016, sediment grab samples (N=874) were collected coast-wide along shore-perpendicular transects that included back-barrier, emergent (beach and barrier island), shoreface, and nearshore environments. Sample locations were selected to re-occupy as closely as possible locat

Data on Midwest stream diatom and stressors, 2013

The objective of this study was to assess the comparative influence of multiple stressors on benthic diatoms at 98 sites that spanned a range of stressors that occurred in an agricultural dominated region in the upper Midwest, USA. The primary stressors of interest included: nutrients, herbicides and fungicides, sediment, and streamflow; though the influence of physical habitat was incorporated in

Foraminiferal Data for Chincoteague Bay and the Marsh Deposits of Assateague Island and the Adjacent Vicinity, Maryland and Virginia

Foraminiferal samples were collected from Chincoteague Bay, Newport Bay, and Tom's Cove as well as the marshes on the back-barrier side of Assateague Island and the Delmarva (Delaware-Maryland-Virginia) mainland by U.S. Geological Survey (USGS) researchers from the St. Petersburg Coastal and Marine Science Center in March, April (14CTB01), and October (14CTB02) 2014. Samples were also collected by

Data for forecasting buffelgrass distribution with global distribution data, local data, and physiological information

This data bundle contains some of the inputs, all of the processing instructions and all outputs from two VisTrails/SAHM workflows, one creating a global habitat suitability model for buffelgrass and another creating a habitat suitability model for buffelgrass in Saguaro National Park, AZ. The bundle documentation files are: 1) '_archive_bundle_metadata.xml' (this file) which contains FGDC metadat

Meteorological Data for Lake Mead and Lake Mohave, Nevada and Arizona, April 2013 to April 2017

In cooperation with the Bureau of Reclamation (Lower Colorado Region), the U.S. Geological Survey collected meteorological data from 4/22/2013 to 4/25/2017 at Lake Mead and 4/11/2013 to 9/30/2016 at Lake Mohave. Meteorological monitoring equipment were mounted to a floating platform located at each lake. The data presented in this data release includes 30-minute mean air temperature, relative humi

Counts of American Pikas and Hoary Marmots in North Cascades National Park 2016-2017

USGS scientists counted American pikas (Ochotona princeps) and hoary marmots (Marmota caligata) in North Cascades National Park, Washington, USA during 2016. Hoary marmots were resurveyed in 2017, primarily by the National Park Service. Pika and marmot counts were collected to assess effects of weather and snowpack dynamics on these species. Counts are measures of relative abundance that may be us

Review of low-temperature tolerance data for 17 species of non-native fishes that have been observed in Everglades National Park

Temperature is an important factor in understanding biogeography and species composition. In south Florida, non-native fishes' tolerance to low temperatures is a critical factor in delineating their geographic spread. We provide a literature review summarizing the current state of knowledge of low-temperature tolerances for all seventeen non-native fishes that have been found in Everglades Nationa

Influence of urbanization on the health of juvenile salmonids in Pacific Northwest perennial streams

Physical and chemical changes affect the biota within urban streams at varying scales ranging from individual organisms to populations and communities creating complex interactions that present challenges for characterizing and monitoring the impact on species utilizing these freshwater habitats. Salmonids, specifically cutthroat trout (Oncorhynchus clarkii) and coho salmon (Oncorhynchus kisutch),

Continuous Resistivity Profiling Data and Associated Data from Greenwich Bay, Rhode Island collected in 2009, U.S. Geological Survey Field Activity 2009-021-FA

As part of a larger investigation to understand groundwater-surface water interactions in Greenwich Bay, Rhode Island, a geophysical survey was conducted from a small research boat on 14-15 May 2009. The specific research objective was to gain an improved understanding of the role of direct groundwater discharge in delivery of excess nitrogen to the bay, which may have contributed to the developme
