The composition and distribution of polynuclear aromatic hydrocarbons (PAH), poly-chlorinated biphenyls (PCB), and coprostanol in suspended particulate matter in the Hudson River–Lower Bay–New York Bight system were investigated. Fused silica capillary gas chromatography and gas chromatographic mass spectrometry were employed for PAH, PCB, and coprostanol determinations. Additionally, dredged material and sewage sludge waste deposits from the bight were size fractionated and analyzed. Between the estuary and shelf and between the benthos and water column, chemical flux mechanisms included Hudson River sediment resuspension and bottom water transport within the estuary, sewage effluent input to harbour–river surface waters followed by seaward transport, landward transport of resuspended bight sediment linked to resuspension of PAH-rich dredged material, and possible transport of sewage-associated organics down the Hudson Valley. The composition of PAH and PCB varied with sediment grain size. Dredged materials were rich in pyrogenic PAH, while PAH in sewage sludge were mainly of a petroleum origin. PAH, PCB, and coprostanol levels were decoupled in the water column particles, probably due to differential solubility behavior of the three compound classes.

ABSTRACT The purpose of this study was to document the distribution and abundance of C 15+ hydrocarbons in sediment samples taken from the Hudson River, the New York Harbor, and across the continental shelf to the continental rise. Collection of 35 of these samples took place in 1975–76 using a multiple corer, a bottom grab, or the submersible Alvin. Materials obtained from these areas were considered representative and included dredge spoils, sewage sludge, and sediment from both the Deepwater Dumpsite 106 on the continental rise and the comparatively cleaner sea floor of the continental shelf beyond the apex of the New York Bight. Total C15+ hydrocarbons are most abundant (3000–6000 parts per million) in areas highly impacted by man—harbor sediments and dredge spoil and sewage sludge disposal areas. Values from the continental shelf are lower (80 ppm) and values from the continental rise are the lowest (40 ppm). Gas chromatographic traces clearly distinguish the hydrocarbons in the dredge spoil and sewage sludge sediment samples from the hydrocarbons found in sediment samples relatively free of sludge or spoil materials.

Abstract This study investigates the dispersal of the Hudson River outflow across the New York Bight and the adjacent inner- through midshelf region. Regional Ocean Modeling System (ROMS) simulations were used to examine the mean momentum dynamics; the freshwater dispersal pathways relevant to local biogeochemical processes; and the contribution from wind, remotely forced along-shelf current, tides, and the topographic control of the Hudson River shelf valley. The modeled surface currents showed many similarities to the surface currents measured by high-frequency radar [the Coastal Ocean Dynamics Applications Radar (CODAR)]. Analysis shows that geostrophic balance and Ekman transport dominate the mean surface momentum balance, with most of the geostrophic flow resulting from the large-scale shelf circulation and the rest being locally generated. Subsurface circulation is driven principally by the remotely forced along-shelf current, with the exception of a riverward water intrusion in the Hudson River shelf valley. The following three pathways by which freshwater is dispersed across the shelf were identified: (i) along the New Jersey coast, (ii) along the Long Island coast, and (iii) by a midshelf offshore pathway. Time series of the depth-integrated freshwater transport show strong seasonality in dispersal patterns: the New Jersey pathway dominates the winter–spring seasons when winds are downwelling favorable, while the midshelf pathway dominates summer months when winds are upwelling favorable. A series of reduced physics simulations identifies that wind is the major force for the spreading of freshwater to the mid- and outer shelf, that remotely forced along-shelf currents significantly influence the ultimate fate of the freshwater, and that the Hudson River shelf valley has a modest dynamic effect on the freshwater spreading.
