Morton, D. C. Abstract The far-UV spectrum of Zeta Pup is surveyed as obtained from scans by Copernicus satellite detectors. Equivalent widths are tabulated for 147 lines from 35 different ions or isotopes of 19 elements in the direction of Zeta Pup. In addition, 52 unidentified absorption lines are listed whose narrow widths indicate an interstellar origin. An attempt is made to report on the relative velocities of the lines, curves of growth and column densities, and interstellar abundances. Suggestions are made for future investigations. Apparently, it is found that: (1) O, P, S, Cl, and Zn are within a factor of 2 of their solar abundances toward Zeta Pup; (2) Mg, Al, Si, Cr, Mn, Fe, Ni, and Cu are depleted by factors of 4 or more; and (3) the depletion generally increases with increasing condensation temperature.
