Scientific paper

We present elemental abundance measurements of 11 damped Lyα systems (DLAs) at .2 < z < 1.5 from recent observations with the Multiple Mirror Telescope. Absorption features from lines of Zn II, Cr II, Mg I, Mg II, Si II and Fe II were found and abundances were determined. We discuss the implications of our measurements for the metallicity evolution of damped Lymanα galaxies. This work was supported in part by the US National Science Foundation grant AST-0206197 and the NASA/STScI grant GO 9441 to the Univ. of South Carolina.
