Dispersal of the Hudson River Plume in the New York Bight: Synthesis of Observational and Numerical Studies During LaTTE (original) (raw)

This study presents an analysis of the dispersal patterns of the Hudson River plume within the New York Bight, synthesizing observational and numerical data collected during the LaTTE project. Key findings indicate that freshwater dispersal is significantly influenced by bulge formation, which redirects freshwater transport toward the estuary even at distances away from the river mouth. Despite the presence of coastal currents, the model simulations revealed that these currents can lead to unexpected upshelf transport of freshwater, challenging traditional assumptions about river plume dynamics. Moreover, the research emphasizes the implications for nutrient cycling and contaminant transport related to the plume's freshwater discharge.
