Inventories and summaries of sound velocity, bathymetry, and bottom characteristics have been compiled for three areas in the North Atlantic Ocean between 15 deg and 65 deg N latitude and east of 50 deg to 65 deg W longitude. The following information is contained in this report: seasonal inventories of sound velocity profiles extending deeper than deep axial depth; charts of the seasonal extent and average axial depth of the upper sound channel; charts of the annual 'strength' of the upper sound channel; charts of the annual extent and average depth of the subsurface sound velocity maximum; annual contour charts of deep axial depth; charts showing bathymetry shoaler than critical depth for summer and winter; an index of the best available bathymetric contour charts; inventories of surficial bottom sediment samples; charts of surficial bottom sediment analysis by grain size classes; an inventory of bottom cores; and a partial inventory of continuous seismic profiles. In addition, a brief analysis is given of water masses that effect sound velocity structures.
