We report results from a survey of neutral fluorine (F I) in the interstellarmedium. Data from the Far Ultraviolet Spectroscopic Explorer (FUSE) were usedto analyze 26 lines of sight lying both in the galactic disk and halo,including lines to Wolf-Rayet stars and through known supernova remnants. Theequivalent widths of fluorine resonance lines at 951.871 A and 954.827 A weremeasured or assigned upper limits and combined with a nitrogen curve of growthto obtain F I column densities. These column densities were then used tocalculate fluorine depletions. Comparisons are made to the previous study of FI by Federman et al. (2005) and implications for F I formation and depletionare discussed.Comment: 32 pages, 10 figures, Accepted to Ap
