Mississippi River Lock and Dam 19 Survey for Asian Carp Sound Deterrent Installation data

A backscatter raster generated from multibeam bathymetry and terrestrial lidar collected simultaneously on November 14, 2019. Backscatter is the reflection of a signal and can help when determining bottom types. Harder bottom types (like rock) reflect more sound than softer bottom types (like mud), and smoother bottom types reflect more sound than rugged bottom types.

Upper Mississippi River Pool 8 Water Temperature and Thermal Infrared Imagery

This georeferenced thermal infrared mosaic of Pool 8 was collected at 0.5 meters/pixel on November 20, 2017 using a mid-wave infrared camera (SC8343, FLIR Systems, Inc., Nashua, NH). This camera was mounted in a Partenavia P68 Observer aircraft and flown at 915m above ground level using a 25mm lens. GPS and inertial measurement unit (IMU) sensors tracked horizontal and vertical position and...

2018 4-band mosaics images of the Emiquon Preserve and Spunky Bottoms Preserve

The 4-band imagery mosaics of the Emiquon Preserve and Spunky Bottoms Preserve (located near the Illinois River in central Illinois) were created using high-resolution aerial imagery collected on September 14, 2018, at approximately 1,2000 meters above ground level resulting in a ground sample distance of 0.15 meters/pixel (6 inches/pixel).

Lake Erie: 2018 Aquatic Vegetation

The USGS developed the second in a series of informative spatial distribution datasets of submersed aquatic vegetation (SAV) in the western basin of Lake Erie. The second dataset was developed by object-based image analysis of high-resolution imagery (US waters < 6 meters deep) collected during peak biomass in 2018 to allow assessments of changes in SAV distribution. Assessing SAV abundance...

TrendPowerTool: A web lookup tool for estimating the statistical power of a monitoring program to detect population trends

A simulation-based power analysis can be used to estimate the sample sizes needed for a successful monitoring program, but requires technical expertise and sometimes extensive computing resources. We developed a web-based lookup app, called TrendPowerTool.

Effects of exposure to ambient UV-B on embryos of Anaxyrus canorus and Pseudacris regilla at various breeding sites near Tioga Pass, California, USA, in 1996 and 1998

We produced this data set as part of a larger, integrated study to assess the statuses of populations of Anaxyrus canorus and the causes of observed effects on fitness at field sites, primarily in Yosemite National Park near Tioga Pass, from 1996 to 2001. ENCLOSURES We used field enclosures to test the hypothesis that exposure to ambient UV-B caused embryo mortality in 1996 and 1998. We c...

Maumee River Legacy and Contaminants of Emerging Concern

Exposure to multiple classes of contaminants, both legacy and those of emerging concern (CECs), were assessed in tree swallow (Tachycineta bicolor) tissue and diet samples from 6 sites along the Maumee River, OH to understand both exposure and possible effects of exposure to those CECs for which there is little avian data. The six sites represented a gradient from intensive agricul

2017-2018 Telemetry data for Asian carp and native fish species at Lock and Dam 19 in the Upper Mississippi River Basin

This dataset includes information derived from a Vemco telemetry array located at Lock and Dam 19 on the Mississippi River near Keokuk, IA. Ten fish species, comprised of both native and invasive species, were detected with this system. Lock Queue Reports, which detail the daily lock operation for river traffic, were obtained from the U.S. Army Corps of Engineers. Temperature data were

PFASs in tree swallows in the Upper Midwest

The exposure and effects of perfluoroalkyl substances (PFASs) were studied at eight locations in Minnesota and Wisconsin between 2007and 2011 using tree swallows (Tachycineta bicolor). Concentrations of PFASs were quantified as were reproductive success endpoints. The sample egg method was used wherein an egg sample is collected, and the hatching success of the remaining eggs in the nes

Backwater Sedimentation in Navigation Pools 4 and 8 of the Upper Mississippi River

Transects in backwaters of Navigation Pools 4 and 8 of the Upper Mississippi River (UMR) were established in 1997 to measure sedimentation rates. Annual surveys were conducted from 1997-2002 and then some transects surveyed again in 2017-18. Changes and patterns observed were reported on in 2003 for the 1997-2002 data, and a report summarizing changes and patterns from 1997-2017 will be re...

St. Croix River and Upper Mississippi River Spectaclecase mussel environmental DNAs: Data

Spectaclecase (Margaritifera monodonta) is a federally endangered freshwater mussel species that has experienced a 55% reduction in range (USFWS 2014) and is currently concentrated in three rivers in the Midwest of the United States (Gasconade, Meramec Rivers, MO, and St. Croix River, WI). Its preference for living under large rocks and boulders has limited detection of new

Mapped weighted wind fetch distances within the Upper Mississippi River System for 2000

Wind fetch is defined as the unobstructed distance that wind can travel over water in a constant direction. Fetch is an important characteristic of open water because longer fetch can result in larger wind-generated waves. The larger waves, in turn, can increase shoreline erosion and sediment re-suspension. Wind fetches were calculated using the wind fetch model available from (http:/%2
