Analysis of Factors Affecting Historical Dissolved Oxygen Trends in Western Long Island Sound
Entry ID: LISES_HistDOtrends

[ Update this Record ]

Summary
Abstract: The purpose of this dataset is to assess the historical decline in dissolved
oxygen concentrations in the bottom region of the Western Long Island Sound.
The primary factors considered in this assassment are the meterological and
hydrological conditions and the nutrient inputs from the point and non-point
sources. The former affects the degree, duration, and depth of density
stratification, as well as, the gravitational circulation and net transport of
the nutrients, phytoplankton and the resulting dissolved oxygen. The secondary
factors considered are the changes in turbidity and light penetration, the
decrease of toxicity, the ratio of dissolved and particulate forms of nitrogen
and changes in denitrification in the water sediment. An understanding of the
relationships among these factors provides a basis for projections of water
quality improvements associated with various management alternates of the Long
Island Sound Study (LISS).
