Track down survey of PCBs in three tributaries to the Niagara River Area of Concern (AOC)

Background Industrial discharges of toxic and bio-accumulating compounds to the Niagara River and its tributaries have occurred over many decades. High concentrations of polychlorinated biphenyls (PCBs) have been found in samples of fish tissue from many locations, including three tributaries to the Niagara River: Tonawanda Creek, Two mile Creek, and Rattlesnake Creek (study reaches listed in...

Coastal System Change at Fire Island, New York

Fire Island is a 50-km long barrier island along the south shore of Long Island, New York. The island is comprised of seventeen year-round communities; federal, state, and county parks; and supports distinct ecosystems alongside areas of economic and cultural value. In addition to providing resources to its residents, the barrier island also protects the heavily-populated mainland from storm...

USGS Alaska Science Center Wildlife Tracking Data Collection

Understanding the short- and long-distance movements of wildlife is critical for a wide variety of ecological research questions and management decisions. Since the mid-1980s, the USGS Alaska Science Center has used information from telemetry devices on wildlife species to determine locations of animals throughout their annual cycles, understand patterns of habitat use, quantify time spent on...

Flaxville Aquifer

The Flaxville aquifer is present in the northern and central parts of the Fort Peck Indian Reservation and consists of sand and gravel that forms extensive plateaus and topographic benches used for dryland farming.  Because many residents rely on groundwater as their primary water supply on the Reservation, the Flaxville and underlying aquifers are important sources of groundwater.  The goal...
