Hampton Roads Regional Water Quality Monitoring Program

In 2014, the U.S. Geological Survey partnered with the Hampton Roads Sanitation District (HRSD) in cooperation with the Hampton Roads Planning District Commission to implement a water-quality monitoring program with the goals of (1) collecting high quality nutrient and sediment data representative of the Coastal Plain, (2) computing loads that can be compared to those developed for the...

Estimating Drought Streamflow Probabilities for Virginia Streams

Planning for drought conditions in Virginia streams is essential to the sound management of water resources and associated riparian and watershed ecosystems. Reliable estimations of the likelihood that stream flows during drought-prone months will exceed specific low-flow thresholds can provide advance warning of drought conditions, allowing extended lead times for improved drought awareness...

Geomorphic Responses to Stream Channel Restoration at Minebank Run, Baltimore County, Maryland

Urban streams frequently undergo severe incision and erosion due to flashy streamflows caused by impervious surfaces in the watershed. The study was designed to investigate the hydrodynamics and geomorphology of a selected reach of Minebank Run before and after stream restoration, in order to determine the effect that stream restoration had on sediment processes in the stream.

Microbial Source Tracking

The USGS Water Microbiology Laboratory in Columbus has been working with numerous agencies and USGS Water Science Centers to analyze water samples for microbial source tracking (MST) markers using the quantitative polymerase chain reaction (qPCR) method. Results from MST analyses help to characterize the effects of various sources of fecal contamination in a watershed. Currently, water samples...

Sediment Network In Ohio

Hellbranch Run is a second order stream tributary to Big Darby Creek. Big Darby Creek was designated a “National Scenic River” in 1994 by the U.S. Department of the Interior. Beginning in 1992, concern about the possible effects of urbanization on water quality in Hellbranch Run (and ultimately Big Darby Creek) prompted the USGS, in cooperation with the City of Columbus, Ohio, to begin...

The North American Breeding Bird Survey: Refining Scale to Provide New Insights

The Challenge: Since 1966, the North American Breeding Bird Survey (BBS) has filled a vital role in identifying at-risk bird species for Federal, State, and private entities. The BBS is a scientifically rigorous population count performed by a highly skilled, largely volunteer work force of nearly 2,500 observers. Every year these observers visit most of the survey’s 4,500 routes, which...

Sediment infilling benefits rainbow trout passage in a baffled channel

Fish are thought to exploit low velocity recirculation zones in the wakes of baffles to take refuge from challenging hydraulic conditions in baffled culverts. Here, we investigate how sediment deposition in the wakes of baffles affects passage and behaviors of juvenile rainbow trout in a baffled experimental flume. High...

Endangered species recovery: A resource allocation problem

Many nations have laws to identify and protect imperiled species and their ecosystems. In the United States, actions taken under the Endangered Species Act (ESA) have prevented many extinctions, but few listed species have recovered to the point where they can have the ESA protections removed (1, 2). One reason for this [among many (3)] is a...

Investigating home range, movement pattern, and habitat selection of Bar-headed Geese during breeding season at Qinghai Lake, China

The Bar-headed Goose is an important species in Asia, both culturally and ecologically. While prior studies have shown Qinghai Lake supports one of the largest breeding areas for Bar-headed Geese, little is known regarding the species movement ecology during the breeding season. In this study, we examined Bar-headed Goose home range size within...

Dynamics of gene expression responses for ion transport proteins and aquaporins in the gill of a Euryhaline Pupfish during freshwater and high salinity acclimation

Pupfishes (genus Cyprinodon) evolved some of the broadest salinity tolerances of teleost fishes, with some taxa surviving in conditions from freshwater to nearly 160 ppt. In this study, we examined transcriptional dynamics of ion transporters and aquaporins in the gill of the desert Amargosa pupfish (Cyprinodon nevadensis amargosae) during...

The Central African Republic Diamond Database—A geodatabase of archival diamond occurrences and areas of recent artisanal and small-scale diamond mining

The alluvial diamond deposits of the Central African Republic (CAR) are mined almost exclusively by way of informal artisanal and small-scale mining (ASM) methods. ASM sites range in diameter from a few meters to 30 meters or more, and are typically excavated by crews of diggers using hand tools, sieves, and jigs. CAR’s reported annual production...
