Visibility correction factors for multiple species of sea ducks and diving ducks using an aerial remote sensing approach

Aerial ocular surveys used by the United States Fish and Wildlife Service provide the most cost and time-efficient method to evaluate the relative abundance and spatial distributions of breeding, staging, and wintering waterbirds. However, the survey method is subject to substantial visibility bias, and visibility correction factors must be calculated to correct for incomplete detection...

Modeling Overview at UMESC

Models seek to describe the natural world around us and how we interact with the world. For example, physical models might help Upper Midwest Environmental Sciences Center (UMESC) visitors understand landscapes, such as the Mississippi River or topology and water flow.

Lake Superior Beach Nourishment and Near-Shore Bathymetric Surveys of Minnesota Point at Duluth, Minnesota

The shoreline, beaches, and infrastructure in Duluth, Minnesota have been degraded along the Minnesota Point barrier island because of high water levels and heavy wave action. The U.S. Army Corps of Engineers (USACE) is exploring the beneficial use of dredge material for beach nourishment on the Lake Superior side of the barrier island.

Kalamazoo River AOC Dam Removal Geomorphic/Habitat Assessments – Reference Reach Identification

The Kalamazoo River Area of Concern (AOC) has multiple dams in various stages of removal, at which restoration work will be completed in the coming years. Hydrogeomorphic data from relatively undisturbed river reaches are commonly used to inform the design parameters of river restoration projects. Reference reaches are selected to have similar prevailing boundary conditions as target restoration...

Bathymetric Surveying at Trempealeau National Wildlife Refuge

The Trempealeau National Wildlife refuge (NWR) is a refuge for breeding and migratory birds. In order to better understand habitat availability and manipulate water levels, a baseline knowledge of bathymetry of the area is needed. Currently, there is no bathymetric surveys for this area specifically and there are very few shallow water surveys especially for highly vegetated wetlands. The U.S...

Developing a Pre-Event Planning Tool for Modified Unified Method Fishing Events (Web Application)

The USGS is adapting the Chinese Unified Method, a fishing harvest method that uses herding techniques and a variety of nets to drive fish and concentrate them into a concentrated area for capture, in the fight against invasive Asian carps. This “Modified Unified Method” incorporates adapted techniques and modern technology for efficient, mass removal of bigheaded carp in North American waters...

Develop Sonar Data Mapping on Three Rivers to Assess Suitability for Native Mussel Habitat

The National Park Service Mississippi National River and Recreation Area and the St. Croix National Scenic Riverway is known for their conservation efforts of threatened and endangered native freshwater mussels. Understanding what constitutes mussel habitat is important for identifying suitable habitat for the conservation and restoration of freshwater mussels. Mussel habitat has not been well...

Hydroacoustic mapping of habitat for threatened and endangered native mussels in the Upper Mississippi River

Understanding the distribution of threatened and endangered freshwater mussels is needed to conserve and restore populations. Sampling for native freshwater mussels typically involves taking quadrat samples in soft substrates and counting the number of mussels in a defined area. However, this methodology is unsuitable for detecting populations of the Spectaclecase mussel ( Margaritifera monodonta...

Pre- and Post-Maintenance Aerial Imagery for Illinois River's Alton through Brandon Lock and Dams, 2019-2021

Most of the locks and dams on the Illinois River are scheduled for closure for repair during the summer of 2020. This project will use 4-band (natural color and color infrared) aerial imagery to document baseline aquatic vegetation and river conditions prior to the closures in the late summer of 2019, and once again in the later summer of 2021 after the locks are reopened.

Feral hog survey over Jean Lafitte National Historical Park and Preserve using high-resolution thermal infrared imagery

The Jean Lafitte National Historical Park and Preserve (JELA) in southeastern Louisiana is being invaded by feral hogs ( Sus scrofa ) and in need a systemic survey to determine where and how many hogs exist within the park boundary. Feral hogs are able to reproduce and increase their range rapidly, they are highly destructive to streams, wetlands, native plants and farm fields, and can spread...
