Chemical and Contaminant Data

The distribution of many contaminants in surface sediments and sediment cores has been measured to determine the sediment quality and dynamics of Long Island Sound. Surface sediments from more than 200 locations and cores from 56 locations were analyzed for contaminants and sediment properties. Link to Contaminants Sampling for more information.

Copper (Cu) concentrations in the surface sediments (0-2cm) of Long Island Sound.

Data for Clostridium perfringens, a bacterial tracer of sewage, for trace element (Silver, Barium, Cadmium, Chromium, Copper, Mercury, Nickel Lead, Vanadium, Zinc, and Zirconium), and for major element (Aluminum, Iron, Manganese, Calcium, and Titanium) composition are presented in a series of reports that are or will be made available through this site. Sediment properties such as grain size, density, water content, and sedimentation rates are also available for selected samples.
