ADC_Keywords: QSOs ; Spectroscopy ; H I data; Redshifts ; Equivalent widths Keywords: cosmology: observations - quasar: absorption-lines - galaxies: evolution Abstract: We present a study of the column density distribution and cosmological mass density of neutral gas from a survey of Damped Lyman-alpha systems in the Sloan Digital Sky Survey III Data Release 9. Description: Our sample of high redshift Damped Lyman-alpha systems (DLAs) and sub-DLAs is presented along with associated metal equivalent widths and/or upper-limits.
