Groundwater Monitoring on Long Island, New York and the Five Boroughs of New York City

The groundwater data-collection network of the USGS New York Water Science Center, Coram Program Office encompasses data collection from approximately 600 groundwater-monitoring wells on Long Island and in the five boroughs of New York City. Data from these stations are collected in varying frequencies to supply our cooperators, stakeholders, and the public with mission critical information....

Delineation of the Saltwater-Freshwater Interface at Selected Well Locations in the Town of Riverhead, NY

Problem The Town of Riverhead in the northeastern Suffolk County includes rural farmland and suburbs and is bounded by the Long Island Sound to the north and Peconic Bay to the southeast. Riverhead’s close proximity to saline embayments and its location along the northeastern discharge area for Long Island’s groundwater flow system makes it vulnerable to saltwater intrusion. Several public-...

Groundwater Information and Data

The U.S. Geological Survey collects groundwater level data at about 20,000 wells nationwide, hundreds here in New York. The USGS provides long-term, accurate, and unbiased information that meets the needs of many diverse users. The USGS collects groundwater data needed by Federal, State, and local agencies for planning and operating water-resources projects and regulatory programs.

Low-Flow Statistics for Indiana Streams

Indiana and Kentucky scientists have produced new low-flow statistics for Indiana streams, specifically for 7-day, 10-year low flow (7Q10); 30-day, 10-year low flow (30Q10); 1-day, 10-year low flow (1Q10); and harmonic mean streamflow. The low-flow statistics are critical for the state of Indiana to administer the National Pollutant Discharge Elimination System (NPDES) permit program,...

Invasive Carp

Adult bighead, silver, and hybrid carp are invavsive species of fish that spread quickly once they are established in a water body. These carp damage habitat and reduce water-quality for native fish. Invasive carp have been confirmed within the Wabash River basin for at least 15 years. Scientists and natural resource managers are extremely concerned about the carp migrating to the Great Lakes...

Ecological Monitoring

Scientists research biology, botany, microbiology, habitat, climate, water quality, and other fields to achieve a comprehensive view of ecosystems and their health. Ecosystems can be easily stressed by human activities, climate change, sediment, nutrients, contaminants, and many other variables. Ecosystem monitoring is critical to ecosystem health and answers important questions about the...

Pesticides

About 1 billion pounds of conventional pesticides are used each year in the United States to control weeds, insects, and other pests. The use of pesticides has resulted in a range of benefits, including increased food production and reduction of insect-borne disease, but also raises questions about possible adverse effects on the environment, including water quality. The...

DNA Barcoding for Identifying Native Bee Species

The Challenge: Traditionally, bee identification has relied on taxonomic methods centered on descriptions of morphological differences between species. However, for many species, separate keys are required for identifying adult males and females and immature life stages. These keys are commonly unavailable. The lack of distinguishing morphological characters useful for separating closely...

Assessing Toxicogenomics Effects of a Synthetic Androgen on Japanese Quail and the Development of an Avian Vitellogenesis Model

The Challenge: Endocrine active chemicals (EAC) are known to interfere with hormonally regulated physiological processes, thereby affecting signaling in the hypothalamic-pituitary-gonadal-liver (HPGL) axis and commonly resulting in reproductive dysfunction. Computational models that relate hormonal and genomic biomarkers within the HPGL axis to the reproductive cycle and ecologically relevant...

Neutral genetic and phenotypic variation within and among isolated headwater Brook Trout populations

Isolated populations are challenging to manage and conserve as they are particularly vulnerable to genetic drift, allelic fixation, inbreeding, and may express markedly reduced phenotypic variability. We sought to improve our understanding of how spatial isolation, occupancy range, and restricted gene flow influence contemporary phenotypic...

Evaluating the relationship among wetland vertical development, elevation capital, sea-level rise and tidal marsh sustainability

Accelerating sea-level rise and human impacts to the coast (e.g., altered sediment supply and hydrology, nutrient loading) influence the accumulation of sediment and organic matter, and thereby impact the ability of coastal tidal wetlands to maintain an elevation consistently within the vegetation growth range. Critical components of marsh...

Pressure core analysis of geomechanical and fluid flow properties of seals associated with gas hydrate-bearing reservoirs in the Krishna-Godavari Basin, offshore India

Physical properties of the sediment directly overlying a gas hydrate reservoir provide important controls on the effectiveness of depressurizing that reservoir to extract methane from gas hydrate as an energy resource. The permeability of overlying sediment determines if a gas hydrate reservoir’s upper contact will provide an effective seal that...

Importance of riparian forest corridors for the ocelot in agricultural landscapes

Worldwide, private lands have attracted increased attention from conservationists, not only because most of the globe is privately owned, but also because private lands can be an asset to the protected area conservation strategy. In Brazil, the riverine Areas of Permanent Protection (APPs) is a key instrument of the Forest Code to protect native...

The Santa Cruz Basin submarine landslide complex, southern California: Repeated failure of uplifted basin sediment

The Santa Cruz Basin (SCB) is one of several fault-bounded basins within the California Continental Borderland that has drawn interest over the years for its role in the tectonic evolution of the region, but also because it contains a record of a variety of modes of sedimentary mass transport (i.e., open slope vs. canyon-confined systems). Here,...

Ecological and management implications of climate change induced shifts in phenology of coastal fish and wildlife species in the Northeast CASC region

Climate change is causing species to shift their phenology, or the timing of recurring life events such as migration and reproduction, in variable and complex ways. This can potentially result in mismatches or asynchronies in food and habitat resources that negatively impact individual fitness, population dynamics, and ecosystem function. Numerous...
