  1. Oyster aquaculture is one of several methods for the restoration of Delaware Inland Bays; however, little is known about its potential impacts on the benthic community of the bays. In this study, water quality parameters were measured and polychaetes were collected from 24 sampling locations at Rehoboth, Indian River, and Little Assawoman Bays from July to October 2016 and 2017. We aimed to assess the impact of Eastern oyster farming under different stocking densities (50 and 250 oysters/gear) and distances away from the sites where the off-bottom gears are implemented (under gears, one meter, and five meters away). No significant impact was detected on polychaetes’ abundance and richness in regard to the presence of oyster gears. The number of polychaetes and species richness was significantly higher in Little Assawoman Bay in comparison to the Indian River and Rehoboth Bays. Results showed that the Ulva lactuca bloom that happened in 2016 could negatively impact the low abundance and richness observed in the polychaetes community. Similarly, the values of polychaetes abundance and species richness did not change significantly in samples that were taken far from the oyster gears. Dominant polychaetes families were Capitellidae and Glyceridae contributing to more than 70% of polychaetes’ number of individuals. Our results help to understand the role of oyster aquaculture in restoring the viability in the natural habitat of the Delaware Inland Bays.

  2. This is an archive of model output from the Regional Ocean Modeling System (ROMS) with two grids and two-way nesting. The parent grid resolution (referred to as Doppio) is 7 km and spans the Atlantic Ocean off the northeast United States from Cape Hatteras to Nova Scotia. The refinement grid (referred to as Snaildel) focuses on Delaware Bay and the adjacent coastal ocean at 1 km resolution. This ROMS configuration uses turbulence kinetic energy flux and significant wave height from Simulating Waves Nearshore (SWAN) as surface boundary conditions for turbulence closure.Ocean state variables computed are sea level, velocity, temperature, and salinity. Also inclued are surface and bottom stresses, as well as vertical diffusivity of tracer and momentum.  The files uploaded here are examples of one time record from each of this dataset. Outputs for the full reanalysis, which comprises 14 Terabytes of data, are made available for download via a THREDDS (Thematic Real-time Environmental Distributed Data Services) web service to facilitate user geospatial or temporal sub-setting. The THREDDS catalog URLs and example filenames available here, for the respective collections, are: - 12 minute snapshots of the Doppio domain 2009-2015: https://tds.marine.rutgers.edu/thredds/roms/snaildel/catalog.html?dataset=snaildel_doppio_history - 12 minute snapshots of the Snaildel domain 2009-2015: https://tds.marine.rutgers.edu/thredds/roms/snaildel/catalog.html?dataset=snaildel_snaildel_history   Garwood, J.
