    Atlantic shelf sand ridge study : physical oceanography and sediment dynamics data report
    (Woods Hole Oceanographic Institution, 1990-02) Dragos, Paul ; Aubrey, David G.
    This report describes and presents the hydrodynamic meaurements made during the Atlantic Shelf Sand Ridge Study at and near Peahala Ridge, offshore of Long Beach Island, New Jersey, in Spring 1985. The intent of this phase of the study was to examine the physical oceanographic and fluid mechanical processes in the vicinity of Peahala Ridge, one of the large shore-oblique sand ridges common in the area, and from this to identify those processes responsible for sand transport near the ridge with particular reference to its generation, maintenance and migration. The field measurement program was carried out from March to May 1985 by scientists and staff of the Woods Hole Oceanographic Institution. It included measurements of currents, temperature, waves, pressure and near-bed velocity profiles. This phase was part of a larger oil industry study that included extensive geological and geophysical measurements of Peahala Ridge and other ridge-and-swale areas of the mid-Atlantic continental shelf.

    Hydrodynamic baseline measurements in New Bedford Harbor
    (Woods Hole Oceanographic Institution, 1990-12) Geyer, W. Rockwell ; Dragos, Paul
    Thls report includes a compilation of hydrodynamic data obtained in New Bedford Harbor, Massachusetts (Figue 1-1), for the purpose of providing baseline information for the selection of an outfall site for a seondary sewage treatment plant for the city of New Bedford. The observations were conducted by scientists at Woods Hole Oceanographic Institution, commencing in August, 1987 and continuing though March, 1988. They included moored and shipboard measurements of fluid velocity, temperature, salinity, dissolved oxygen and turbidity. The measurement program was designated as the "New Bedford Circulation Study", or NBCS. The study indicates that there are a variety of mechanisms responsible for the transport and exchange of water-masses, of which tidal currents are the most energetic, but wind-driven flows are likely the most effective at renewing the water within the Harbor. Estimates of residence times indicate minimum residence times of less than 2 days during periods of strong winds, and maximum residence times of 4 days or more in periods of weak to moderate south winds. Vertical stratificaton is weak in the winter and moderate in the summer, and it has a notable influence on vertical mixing and on the magnitude of shear currents.
