    Model Sensitivity & Comparison to Glenn and Grant (1987)

    Calculated model profiles: (a) stability parameter, (b) mean concentration, (c) mean current and (d) sediment transport. Left panel shows comparison with Glenn & Grant (1987) (dash) for several values of the free parameter z2. Right panel shows model sensitivity to gamma. GAMMA is depth-integrated sediment transport.



    LEO-15 Research Area








    Rutgers' Long-term Ecosystem Observatory is in 15 meters of water (LEO-15) is located in the southward extenson of the New York Bight. The study site is located at Node A on top of a shore-oblique submarine sand ridge.




    This instrument is the Benthic Acousitc Stress
    Sensor (BASS). The unit consists of 4 acoustic
    current meters that measure both waves and
    currents. It can also produce vertical current
    profiles to measure shear stress.







    This panel shows the time series of mean current and maximum wave orbital velocity (ub) derived from BASS data. This 30-day record is used to calibrate and verify the bottom boundary layer model presented above. Acoustic concentration and ripple data collected by WHOI scientists are also used.
