This report presents a seasonal oceanographic environmental summary for North Atlantic area NA-1, northeast of Bermuda -- 33-38 deg N x 56-62 deg W. The contents of this environmental summary represent a statistical cross section of the conditions which can exist in this region. Velocity structure data resulted from an analysis of Nansen cast and bathythermograph data from the Code 556 digital oceanographic data bank. Additional environmental data from various other sources provided additional information. Special Code 556 computer processing programs, which determine layer depth, gradients, and other profile characteristics, were used in carrying out the velocity profile analysis. Data generated for this report is primarily for use by NUC system analysts in selecting environmental inputs to sonar system performance predictions.
