This technical note describes the Deep-Tow Acoustics/Geophysics System (DTAGS) compressional velocity database, a compilation of compressional velocity functions derived from DTAGS deep-tow multichannel seismic data. Three geologically distinct areas are represented by the velocity functions included in this database: thick turbidites on the Bermuda Rise, fine grained terrigenous sediments containing methane hydrate on the Blake Outer Ridge, and thin sediments overlying young basement near the Juan de Fuca Ridge. Horizontal sampling frequency of the database ranges from 45 to 230 m. Vertical sampling frequency ranges from 20 to 300 m. These compressional velocity profiles, functions of geographic region, layer thickness and range along the ship track, were determined from the DTAGS multichannel seismic data using standard semblance velocity analysis procedures.
