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, low marshes—were disappearing. To help determine the cause(s) of this loss, the NYSDEC, in collaboration with Stony Brook University's School of Marine and Atmospheric Sciences (SoMAS) and the U.S. Geological Survey (USGS), established a monitoring program in 2008 that has been conducted on and in the tidal wetlands of East Creek,...

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 relative magnitude and geographic origin of sources of loadings of pathogens (from urban/storm runoff, submarine groundwater discharge, etc) on Long Island, nor clear understanding about the host organisms from which they originate (such as human, mammals, or birds). Pathogen loads to specific embayments are affected by watershed land-use,...

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 the SCDHS, began a 3-year study in 2002 to sample surface waters in selected wetlands for insecticides which were sprayed seasonally from a truck or helicopter as part of the county's vector-control program. These insecticides include Altosid (methoprene) and Scourge [1:3 ratio of resmethrin and piperonyl butoxide (PBO)]. Methoprene...

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, and during aperiodic events. In the estuaries surrounding Long Island, such events may include wastewater treatment plant failures, harmful algal blooms, and extreme weather. The U.S. Geological Survey (USGS) has extensive experience with continuous water-quality monitoring at fixed locations along the coast that provides valuable...
Wetlands provide numerous ecological and economic benefits to coastal communities having value as nursery, feeding, and refuge areas for many commercial and recreational fisheries, and they significantly contribute to the base of the food web. Wetlands trap sediments, reduce turbidity, and absorb nutrients and pollutants thereby improving water quality. They also provide an important buffer against wave energy from coastal storms; however, these benefits are deteriorating with the health of these ecosystems. Wetland health and sustainability are dependent on several factors including hydrology, sediment flux, vegetation, nutrient inputs, coastal development, and invasive species. Over the past several decades...
