Assessment of fecal contamination sources to Alley Creek, Queens County, New York
PROBLEM Alley Creek, a tributary to Little Neck Bay (Queens County, New York; figure 1) has been designated as impaired by the New York State Department of Environmental Conservation (NYS DEC) for primary and secondary contact and included on the 303(d) Impaired Waterways for pathogens related to combined sewer overflow contributions. The New York City Department of Environmental...
Southeastern New York Coastal Monitoring
USGS monitoring data for estuary and coastal-ocean sites in the southeastern New York region and links to related projects with more information about coastal flood hazards, water quality, and other topics. The USGS operates the most extensive satellite network of tide-gaging stations in the region, many of which form the backbone of flood-warning systems. The USGS provides current ("real-time")...
Using Microbial Source Tracking to Identify Pollution Sources in Pathogen Impaired Embayments in Long Island, New York
Problem The presence of pathogens in Long Island marine embayments and the hazards they pose to marine resources and human health is of increasing concern. Many waterbodies on the New York State Section 303(d) List of Impaired Waters have pathogens listed as the primary pollutant that are suspected to originate from urban/storm runoff. There is neither a clear understanding of the...
Continuous and Spatially Distributed Dissolved Oxygen Monitoring in Long Island Estuaries in Support of Coastal Resource Management.
Problem Dissolved oxygen (DO) is an important indicator of water quality that until recently has been cost-prohibitive to monitor extensively in both space and time. Continuous water-quality data, particularly in coastal environments with bidirectional tidal flow, is necessary for resource managers to understand the dynamic changes in water quality that occur tidally, daily, seasonally...
Monitoring of Waterways for Mosquito Insecticides, Suffolk County, New York
Introduction Mosquitoes are the principle vector of the West Nile Virus (WNV) which causes infections in humans and animals and has emerged as a public health threat throughout Long Island, NY. The WNV was first detected among birds and mosquitoes by the Suffolk County Department of Health Services (SCDHS) in 2000. In response to the public health concern, the USGS in cooperation with...
Monitoring Tidal Water Elevation and Water Quality to Assess Tidal Wetland Loss in Four Embayments of Long Island Sound, New York
Introduction Recent trends analysis examining the effectiveness of tidal wetland regulations and the regulatory program of the New York State Department of Environmental Conservation (NYSDEC) revealed that the regulations and regulatory program were highly effective in stemming the historic "fill and build" activities. However, the trends also revealed that tidal wetlands—specifically...
Geospatial datasets of AUV observations including bottom dissolved oxygen in Great South Bay, Long Island, New York, August 2016
This dataset provides locations and values of water quality parameters from a four-day survey conducted between August 23, 2016 and August 26, 2016 using an Autonomous Underwater Vehicle (AUV) in Great South Bay, New York. Measured parameters include bottom dissolved oxygen (DO), salinity, specific conductance, water temperature, and pH. During the four day period, data was collected...

Assessment of fecal contamination sources to Alley Creek, Queens County, New York, August 2020–June 2021
Alley Creek, a tributary to Little Neck Bay in Queens County, New York, has been designated by the New York State Department of Environmental Conservation as impaired (Class I) for fecal coliform because of pollution from combined sewer overflow, including stormwater runoff. The U.S. Geological Survey, in cooperation with the New York City Department of Environmental Protection...

Large natural pH, CO2 and O2 fluctuations in a temperate tidal salt marsh on diel, seasonal, and interannual time scales
Coastal marine organisms experience dynamic pH and dissolved oxygen (DO) conditions in their natural habitats, which may impact their susceptibility to long-term anthropogenic changes. Robust characterizations of all temporal scales of natural pH and DO fluctuations in different marine habitats are needed; however, appropriate time series of pH and DO are still scarce. We used multiyear...
