This report consolidates the Computer Programs in Oceanography Preliminary List (NODC Progress Report P-12) of June 1963 and the Supplementary List issued September 1963. Revisions and corrections have been made, and a considerable amount of additional material has been included. The listings are arranged, as in previous compilations, alphabetically by agencies and institutions and are grouped by computer make and model. Abstracts of the computer programs have been revised to contain the estimated running time and, under 'Program Description', the error introduced by mathematical techniques used in computation.
