Temporal Changes in Grain Size and Organic-Mineral Aggregates
in Surficial Sediments Near the Massachusetts Bay Outfall Site
By Richard R. Rendigs and Michael H. Bothner
Based on U.S. Geological Survey Report 01-499, December 2001
This report summarizes the time-series analyses of grain size distribution and the abundance of organic-mineral aggregates in surface sediments at two monitoring stations near the Massachusetts Bay Outfall. Sediments, especially the finer fractions, can adsorb contaminants from sea water and exert a strong influence on the transport and ultimate distribution of contaminants. Therefore, it is important to know the extent to which sediment characteristics in Massachusetts Bay can change in response both to natural events, such as storms, and to the start of the new sewage outfall.
