Report On Spectral Wave Modeling : Extended Study Of The Effects Of Sand Mining On The Wave Regime At Sandbridge, Virginia - Comparison Of Results Using A Phase-Revolving And A Phase-Averaging Spectral Wave Model (Ref/Dif S And Swan), John D. Boon, Sung Chan Kim
Reports
In an earlier report (Boon, 1998), findings were presented from a wave modeling study whose purpose was to investigate the effects of sand mining on the nearshore wave regime at Sandbridge, Virginia (Fig . 1). Using a phase-resolving spectral wave model, REF/DIF S (Kirby and Ozkan, 1992), a representative set of hypothetical storm waves was propagated across a 20 km section of the inner shelf from approximately the 20 m depth contour offshore to the 11 m depth contour inshore . Subsequent simulations were then made that tested local effects of shoaling and refraction on wave heights within a fine-scale …

SeaWiFS estimates of surface chlorophyll concentrations are reported for the region of the U.S. JGOFS study in the Southern Ocean (similar to 170 degrees W, 60 degrees S). Elevated chlorophyll was observed at the Southern Ocean fronts, near the edge of the seasonal ice sheet, and above the Pacific-Antarctic Ridge. The elevated chlorophyll levels associated with the Pacific-Antarctic Ridge are surprising since even the crest of the ridge is at depths > 2000 m. This elevated phytoplankton biomass is likely the result of mesoscale physical-biological interactions where the Antarctic Circumpolar Current (ACC) encounters the ridge. Four cruises surveyed this region between …

Three Dimensional Hydrodynamic-Sedimentation Modeling Study : Hampton Roads Crossing, Lower James River, Virginia, John D. Boon, Harry V. Wang, S. C. Kim, Albert Y. Kuo, G. M. Sisson
Reports
A three-dimensional hydrodynamic-sedimentation computer model, HYSED-3D, was used to evaluate the effect of bridge-tunnel infrastructure for a proposed highway crossing of Hampton Roads on the physical characteristics (tides, currents, circulation, salinity, and sedimentation) of the James River estuary in Virginia. Model-represented infrastructure included tunnel islands and bridges on pilings connecting the islands to interstate highways in Newport News, Hampton, Norfolk, and Portsmouth, Virginia. Combinations of these elements occur in each of three proposed crossing routes designated Alternative 1 (Hampton-Norfolk), Alternative 2 (Hampton-Norfolk, Norfolk-Portsmouth), and Alternative 9 (Newport News-Portsmouth-Norfolk). Simulation comparisons were made between the existing waterways and infrastructure in Hampton …

Sensory Development In Settlement-Stage Larvae Of Caribbean Labrids And Scarids: A Comparative Study With Implications For Ecomorphology And Life History Strategies, Monica R. Lara
Dissertations, Theses, and Masters Projects
The sensory capabilities of settlement-stage fishes are unknown but this information is necessary to studies of larval settlement and recruitment. The morphology of the cephalic lateral line, eye and external olfactory organ of thirteen species of settlement-stage Caribbean labroids was described. Scanning electron images of the cephalic lateral line neuromasts, lateral line canals and olfactory epithelia and histological studies of the retinae and morphological measurements of visual acuity were used to assess the level of sensory development attained at settlement. The sensory capabilities of settlement-stage fishes are discussed in relation to the possible cues settlement-stage fishes may be using to …
Measurements Of The Shape Of Sand Ripples, Jerome P-Y Maa, S-H Ou, C-J Huang
Measurements Of The Shape Of Sand Ripples, Jerome P-Y Maa, S-H Ou, C-J Huang
VIMS Articles
Laboratory experiments have been conductef. for determining what would be the correct selection of acoustic devices for measuring the shape of sand ripples. The results reveal that a toneburst type signal generator with I or 2 watts will be sufficient to drive the transducer. A transducer with focus and reasonable size would be the best choice. While measuring, the ratio of measuring distance (between the transducer and sea floor) and the transducer's focus length should be maintained at a ratio between 90% and II 0% for best results.

Phytoplankton Growth Rates In The Ross Sea, Antarctica, Determined By Independent Methods: Temporal Variations, Walker O. Smith Jr., D. M. Nelson, S. Mathot
VIMS Articles
The development of the seasonal phytoplankton bloom in the Ross Sea was studied during two cruises. The first, conducted in November-December 1994, investigated the initiation and rapid growth of the bloom, whereas the second (December 1995-January 1996) concentrated on the bloom's maximum biomass period and the subsequent decline in biomass. Central to the understanding of the controls of growth and the summer decline of the bloom is a quantitative assessment of the growth rate of phytoplankton. Growth rates were estimated over two time scales with different methods. The first estimated daily growth rates from isotopic incorporation under simulated in situ …
