The Missing Silica Sink: Revisiting the Marine Sedimentary Si Cycle Using Cosmogenic 32Si

“…The sound receives inputs of anthropogenic wastes from sewage wastewater from the New York City-Connecticut area as well as cropland, urban runoff, and groundwater. The estuary consists of three major basins, and the site sampled in this study comes from Smithtown Bay, located in the Central Basin and representative of silty/clay sediments which cover~60% of the total area of the sound (Sun et al, 1994;Latimer et al, 2014). Modeling of fluvial inputs to the Sound suggests that about 45% of the total sediment supply has a source in the neighboring coastal ocean (Kim & Bokuniewicz, 1991), with the majority of muddy sediment accumulating in the western and central sound (Kim & Bokuniewicz, 1991;Latimer et al, 2014).…”

The top few centimeters to decimeters of deposits in the sound are rapidly reworked by bioturbation and are underlain by a slower reworked layer down to 1-2 m (Aller & Cochran, 1976;Goldhaber et al, 1977;Benninger et al, 1979).…”

Foraging hotspots of common and roseate terns: the influence of tidal currents, bathymetry, and prey density

“…NECOFS hindcasts were not available for the times of our field work, so we instead obtained six days' worth of model predictions at hourly resolution from 29 October to 4 November 2016. Because currents in the Race are forced primarily by the M2 semidiurnal tide, and because the water column in this area never stratifies (O'Donnell et al 2014), we expected tidal currents from this time period to be adequately representative of those during the study period.…”
