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).
