Description:
Rivers and estuaries like the Hudson River Estuary are a focus of human activity. An important component for successful management of these systems is a detailed understanding of sedimentary processes and related contaminant distribution. We developed a new method that combines geochemical analysis of sediment cores and interpretation of seismic profiles to rapidly map extent and volume of potentially contaminated sediments deposited during the 20th century.
The goal of this project is to determine distribution and volume of recent sediments in a section of the Hudson River Estuary and compare the results with previous studies in the Haverstraw Bay and Tappan Zee sections. The work will include analyzing selected sediment cores that are available in the Lamont core repository, determining the thickness of recent sediments in these cores, and integrating these results with the interpretation of seismic profiles from the area. The resulting volume estimates will be compared to results from other areas of the Hudson River Estuary.
