NSA provides environmental services to Federal agencies throughout the United States. A variety are highlighted below:
Review the Effects of Sediment Disposal on the Ecology of the Snake River. USACE. NAICS Code – 541620
NSA was authorized by the Walla Walla District, Washington State, of the Army Corps of Engineers (USACE) to compile and synthesize aquatic habitat data from the Snake River from 1983 to 2010. The compiled report has helped the USACE to evaluate environmentally acceptable and beneficial measures for managing dredged sediment in the Snake River system, particularly the effects of sediment disposal on salmonid fish populations. Results of existing studies and studies conducted in the lower Columbia River and its estuary suggest that creating shallow water habitat benefit endangered Snake River salmon fish (salmonids) by providing feeding and rearing areas, in contrast to the current habitat limited condition of the reservoirs.

Biological Monitoring. BLM. NAICS Code – 541620
NSA was selected by the US Bureau of Land Management (BLM) in 2010 to participate in one of the first large scale mine-related biological monitoring studies in Alaska.
The study was designed to better understand the contaminant load in lower trophic levels of the aquatic food web and the relationship to abandoned mines on public lands, specifically the Red Devil Mine (RDM), an abandoned cinnabar mining and mercury (Hg) retort site on the banks of the Kuskokwim River in western Alaska.
The resulting information was used in the remediation of abandoned mines and subsequent sampling to monitor contaminant levels in the future. The mine was first opened in the 1930’s and closed in 1971. During the mid-1950’s, RDM was a leading producer of mercury; production records indicate that at least 35,000 flask of mercury were produced there, which equates to roughly 1,330 tons.
Wyoming, USA Range Heath Study. BLM. NAICS Code – 541620
NSA was responsible for collecting data on 17 permanently marked 10-Plot trend transects as part of range health assessment in western Wyoming. Each transect consisted of ten (10) 9.6 square foot plots located along transect lines varying in length up to 1,000 ft.
NSA provided a minimum of 2 personnel on each transect in the field, as well as equipment, tools, materials, supervision, and other items, and incidental services necessary to perform trend monitoring.
The total area covered during the survey was approximately 82,000 acres across three counties. BLM Worland, Wyoming District.

Florida, USA Caracara Monitoring & Tagging in Support of Kissimmee River Restoration (KRR) Project, Okeechobee & Highlands Counties. USACE. NAICS Code – 541620
NSA assembled and reviewed existing scientific literature and data relevant to the proposed project nesting survey, with an emphasis on caracara (Caracara cheriway) historical habitat use, distribution, nesting behavior, threats, disturbance, and all other scientific surveys conducted for this species. The data reviewed included pre-survey evaluations of maps, including, but not limited to, aerial photographic maps with detailed contract areas provided by the USACE, U.S. Geological Survey (USGS) 7.5 minute topographic maps, U.S. Department of Agriculture (USDA) soils maps maintained by the Natural Resource Conservation Service (NRCS), and South Florida Water Management District (SFWMD) maps. All data, literature, and reports were compiled for review prior to meetings and/or field work.
NSA conducted nesting surveys during peak caracara nesting season 600 meters from the KRR Contract 12A project footprint. NSA followed the appropriate nest survey procedures in the Survey Protocol for Finding Caracara Nests and the 2012 Caracara Project Work Plan. The surveys performed verified or updated nest locations as needed and identified new nests. If monitoring determined that a nest had failed, monitoring of the pair continued at least through April 30, as re-nesting could occur. Monitoring identified reproductive status, nest locations, nest success, and fledging success of nesting caracaras in the project area up to 600 meters from the restoration project footprint.

Hydrologic and Water-Quality Monitoring Analysis
USGS Virginia Water Science Center
Objective: Collaborate with USGS hydrologists to assemble, analyze, interpret, and communicate hydrologic and water-quality data; initially focusing on models for estimating nutrient and sediment loads entering the Chesapeake Bay watershed.
NSA staff is researching a new method to explore potential drivers of water-quality trends using differential spatially-referenced regression in the Chesapeake Bay watershed. A new method is desired to establish direct linkages between regional patterns of observed water-quality changes and drivers. Examples include management actions, watershed properties and climatic forcing variations, within finite time scales. The resulting model can be used for predicting water-quality effects under various management scenarios in a spatially-distributed dynamic watershed system. This new methodology is expected to be published in 2018.
Inner Continental Shelf Delmarva Peninsula Coastline Research
USGS Woods Hole Coastal and Marine Science Center
Objective: Mapping and identifying sediment ridge features found on the inner continental shelf offshore in the Delmarva (Delaware-Maryland-Virginia) Peninsula.
NSA researchers are developing auto-classification methods to identify these ridge features and create geospatial images of their locations. Identifying these offshore sediment features helps to better constrain controls on coastal vulnerability and evolution, the region’s sediment sources, transport pathways and sinks with the over-arching goal of understanding the coastal geological framework of this area at storm-event and longer time scales.
American Shad Research
USGS Leetown Science Center’s S.O. Conte Anadromous Fish Research Center
Objective: Determine the impacts of temperature, energy use and efficiency of fish passage facilities pm the spawning success of American shad.
American shad (Alosa sapidissima) is an economically and ecologically important anadromous species native to eastern North America. Many American shad populations have declined due to the impact of dams on their upstream migration. Understanding how American shad utilize their energy resources during upstream migration is critical to designing effective fish passage ways around dams and the overall conservation of a species that is important to recreational and commercial fisheries. For this project, NSA staff is measuring American shad fat content with new microwave-based technology called the Fatmeter.
Bird Banding Laboratory
USGS Patuxent Wildlife Research Center
Objectives: Maintain the overall quality of the bird banding and band encounter data used for research, management, and conservation of migratory bird populations and digitize BBL banding schedules.
Since 1920, the Bird Banding Laboratory (BBL) has tracked the data obtained from birds banded in North America. However, these hundreds of thousands of entries have been most inaccessible.
The BBL has several hundred bird banding schedules representing thousands of banding events prepared to scan and digitize. The data from these bands allows researchers to study bird migration, behavior, life-span and survival, and population health and growth. This data has enabled managers to set science-based hunting regulations.
Under the direction of NSA and USGS, one important component of this work involves teaching student volunteers how to scan documents for digitization and to track data using spreadsheets. These students work tirelessly to digitize this banding information and have scanned almost 180,000 sheets of banding data since 2015 and can now be uploaded to the BBL data system. In addition, the data is utilized in the Biodiversity Information Serving Our Nation (BISON) web app which is the U.S. Federal resource for biological occurrence data.
