Abstract: Wave-Climate Studies in Baltimore Canyon Trough OCS--Environmental Implications

V. Goldsmith, R. A. Gammisch, P. S. Rosen

The VIMS-BLM Baltimore Canyon Trough Wave Climate Model (BCTWCM) encompassing 97,650 depths on a 0.5 n. mi. grid in the continental shelf area between Montauk Point, New York, and Cape Henlopen, Delaware, has been computed for 12 representative conditions. This model, encompassing the recently leased blocks, was produced rapidly (in six months) to assist in the benchmark OCS environmental studies by providing basic aerially distributed wave information, and by integrating these data with other ongoing sedimentologic and biologic studies.

Data computed include wave-ray diagrams, shelf-contour diagrams of wave height and maximum horizontal bottom-wave orbital velocity, and shoreline histograms of wave-ray density, wave height, and wave energy. The data indicate several specific areas in the northwest and southwest parts of the lease block areas (which include some of the most expensive blocks) that contain areas of wave-energy concentration for the 10- and 12-sec waves. The most significant geomorphic feature, with respect to wave refraction, is the Hudson Shelf Valley, which is upwave from the lease block areas. Superimposed on the resulting wave patterns in this lease block area are the locally highly variable wave effects induced by linear sand ridges. Concomitant temporal and spatial variability also is present in the sedimentologic and biologic characteristics.
