Long-Term Warming And The Size And Phenology Of Long Island Sound Plankton
… water temperatures in the Central Basin of Long Island Sound (LIS) from the late 1940s until 2012 indicates a warming rate of 0.03°C per year, with recent summer temperatures increasing most consistently. During this warming trend, the proportion of chlorophyll produced by smaller …

Microbial Degradability of Terrigenous, Marsh-Exported, and Estuarine Colored Dissolved Organic Matter in Long Island Sound
<p>The Long Island Sound is one of the world's most urbanized estuaries, polluted from excess nutrients which impact the quality of water through increased biological productivity. Dissolved organic matter (DOM) is a sensitive indicator of anthropogenic pollution and nutrient enrichment in coastal …

Optical Signatures of Bioavailable and Terrigenous Dissolved Organic Matter Across Long Island Sound and Hudson River Estuaries
<p>Optical measurements, from <em>in situ</em> to satellite-based sensors, provide a powerful framework for examining the sources, sinks, and transport pathways of dissolved organic matter (DOM) across the land–ocean aquatic continuum. By integrating observations across spatial and temporal scales, …

Long Term Nutrient and Chlorophyll a Dynamics across Long Island Sound and Impacts on Dissolved Oxygen Conditions within the Western Sound (1991-2019)
… and persistent water quality problems in Long Island Sound (LIS) over the past decades with major impacts on commercial industries, ecology, and recreational activities in the region. Recognizing these problems, the EPA enforced three phases of the Clean Water Act (CWA) to reduce nitrogen …

Two Cost Analyses in Resource Economics: The Public Service Costs of Alternative Land Settlement Patterns and Effluent Allowance Trading in Long Island Sound
… options for meeting water quality goals in Long Island Sound. The objective the first analysis is to determine the cost to local governments of providing water distribution and wastewater collection services to alternative spatial forms of residential development. Components of spatial form …

Trading pollution for water quality : assessing the effects of market-based instruments in three basins
… Offset Program in North Carolina; and the Long Island Sound Nitrogen Credit Exchange in Connecticut. Although reallocating reduction efforts through trades to achieve cost-effective solutions is supposedly the major benefit of market-based instruments, only dischargers in the Long Island …

Physical Processes that Affect Hypoxia in the Thames River Estuary, USA
… River, the third largest drainage basin to the Long Island Sound. Hypoxic bottom-water conditions in Norwich Harbor have been documented during previous summers, but the evolution and variability of the low-oxygen levels have not been effectively shown through prior observations. Developing a …

The Solution In The Sea: New York recently legalized commercial kelp farming. Will it help solve the state's environmental and economic woes?
… fueled by nitrogen pollution, transformed the Long Island Sound into a dead zone. Though the area has somewhat recovered, the people and marine life that rely on these waters still feel the impact decades later. Many are hoping that kelp farms can help. Kelp farming is a nature-based mitigation …

Selection of Spawning Habitats by Horseshoe Crabs (Limulus polyphemus) along the Complex Connecticut Coast
… conflict. This research focused on the Long Island Sound population of horseshoe crabs and aimed to characterize the coastal habitats of Connecticut by various traits using remote sensing and geographic information system technologies. Data layers representing the coastal area were …

Development of an inline cleaning procedure and a concentration method for analyzing low levels of organophosphate flame retardants and plasticizers in sediment
… in 10 surficial sediment samples collected in Long Island Sound (LIS) were analyzed. TCPP (chlorinated) had the highest concentration, consistent with its highest usage and its persistency in the environment. TBEP (non-chlorinated) had the second highest concentrations in LIS sediment. The …

Feasibility analysis and design of a flood barrier concept for the City of New York
… Bridge, seals the City off from the Long Island Sound, which utilizes a vertical flap gate. The other barrier spans between Sandy Hook and Breezy Point utilizes a horizontally rotating arch gate. A life-cycle benefit analysis was performed to determine the time for a barrier of each …

Interactions between two invasive crab predators, Carcinus maenas and Hemigrapsus sanguineus, and consequences for the native community
… C. maenas as the dominant predatory crab (Long Island Sound and southern Gulf of Maine, but progressing northward). Both conspecific and heterospecific interference strongly affected C. maenas, likely limiting its population size and subsequent impacts. In contrast, interference had little …

The dynamics and kinematics of the coastal boundary layer off Long Island
… which investigated the first 12 km off Long Island's south shore, are analyzed and discussed. Moored current meter records indicate that the nearshore flow field is strongly polarized in the alongshore direction and its fluctuations are well correlated with local meteorological forcing. …

Towards Sociobiogeochemistry: Critical Perspectives on Anthropogenic Alterations to Soil Nitrogen Chemistry via U.S. Urban and Suburban Development
… focused on residential land use in the Long Island Sound (LIS), a waterbody significantly impacted by eutrophication due to excess nutrient input. Land use in this watershed is dominated by single family homes and lawns, creating concern about nutrient pollution to the LIS from these …
