    Long Island Sound is a tidal estuary of the Atlantic Ocean, lying predominantly between the U.S. state of Connecticut to the north, and Long Island in New York to the south. From west to east, the sound stretches miles ( km) from the East River in New York City, along the North Shore of Long Island, to Block Island Sound.A mix of freshwater from tributaries and saltwater from the ocean. Water quality improvement is the Harbor Estuary’s biggest success story. The short and long term trends for most water quality indicators show that conditions are improving over time. Dissolved oxygen levels in the water, critical for fish survival, are increasing. There is less garbage floating in the water and along the shoreline than.

      The Long Island Sound got its report card back,and grades ranged from an "A" to an "F" depending on the region.. The water quality of the Long Island sound greatly differs from the Western Author: Paige Mcatee. Long et al. () demonstrated substantial shifts in community structure associated with water column dissolved oxygen levels below 3 mg/L. In general, the overall density of benthic infauna and species richness were reduced as dissolved oxygen decreased.

Temporal trends in dissolved oxygen (DO) concentrations in Long Island Sound (LIS) over the past four decades. A general east-to-west gradient of decreasing bottom DO was evident in all historical. Distribution of dissolved oxygen in the waters of Western Long Island Sound.

The most oxygen that can be dissolved in Long Island Sound at summer water temperatures is about mg/l.

The variability of bottom dissolved oxygen (DO) in Long Island Sound, New York, is examined using water quality monitoring data collected by the Connecticut Department of Environmental Protection.

Long Island Sound (LIS) (see Fig. 1) has traditionally suffered from hypoxic conditions, which have been observed in the western sound since the early a in LIS became more severe toward the end of the s (Parker and O'Reilly, ).In the states of Connecticut and New York and the Environmental Protection Agency (EPA) adopted a plan for Phase III Actions for Cited by:   Dissolved Oxygen in Long Island Sound Bottom Waters: 31 August—September 2 Connecticut Department of Energy and Environmental Protection.

The book effectively outlines the case for Reviews: 1. An increasing body of evidence suggests that much of the trace metal contamination observed in coastal waters is no longer derived from point-source inputs, but instead originates from diffuse, non-point sources.

Previous research has shown that water temperature and dissolved oxygen regulate non-point source processes such as sediment diagenesis; however, limited information is Cited by:   To keep you up-to-date on your beloved beach getaways, here are some fun facts about Long Island Sound: Long Island Sound is a tidal estuary, which is an body of water consisting of both fresh and salt water 90% of the freshwater comes from three main rivers in Connecticut: the Housatonic, the Thames, and the Connecticut rivers.

Concentrations of dissolved oxygen in the ocean seem to correlate well with climate instabilities over the pastyears. For example, the concentration of dissolved oxygen. • Along-Sound gradients from EXRK, FB02, and WS) • & data, also applied to SWEM • Subtidal advection dominated over tidal dispersion McCardell and O’Donnell, Estimates of Horizontal Fluxes in the Western Long Island Sound.

As the chart shows, the concentration of dissolved oxygen in surface water is affected by temperature and has both a seasonal and a daily cycle.

Cold water can hold more dissolved oxygen than warm water. The research undertaken specifically investigated bottom water dissolved oxygen, as well as hydrogen sulfide and ammonia (two end-products of organic matter degradation that are known to negatively affect many organisms), as structuring influences on the benthic habitat quality and associated benthic communities of western Long Island Sound.

Oxygen depletion in the upper ocean is commonly associated with poor ventilation and storage of respired carbon, potentially linked to atmospheric CO2 levels. Iodine to Cited by: "Dissolved Oxygen in a Stream May Vary from 0 Mg/l to 18 Mg/l.

Changes in water temperature and dissolved oxygen levels may lead to a reduction of oxygen in surface sediment as well as cause leaching of contaminants out of the surface sediments.

Such changes have the potential to impact numerous organisms.
