Hydrodynamically Defined Bathymetry.

Abstract

The ocean depth data collected by G. M. Smith, H. M. Menard, and G. Sharman in 1966 at the Scripps Institute of Oceanography are rearranged and linearly interpolated to fit a new 1 deg by 1 deg spherically graded grid system suitable for modeling of global ocean tides and currents. The original data bank is corrected for various listing errors. All land, gridwise disconnected border seas, and shallow coastal waters of less than 5 m depth are deleted from the main ocean basin. The total depth range is confined between 20 and 7000 m. At over 3000 grid cells, hydrostatically defined original data are hydrodynamically redefined to account for barrier effects of narrow ocean ridges and other obstacles that cause significant distortions and retardations of ocean tidal waves and other ocean currents. The revised bathymetric data are tabulated in this report and are available in tape form from the Naval Surface Weapons Center, Dahlgren, Virginia. (Author)
