We present new chemical abundance measurements of 16 damped Lyα systems at z > 1.5 and update our previous abundance analyses. The entire database presented here was derived from HIRES observations on the Keck I telescope, reduced with the same software package, and analyzed with identical techniques. Altogether, we present a large, homogeneous database of chemical abundance measurements for protogalaxies in the early universe, ideal for studying a number of important aspects of galaxy… 
The ESI/Keck II Damped Lyα Abundance Database
This paper presents chemical abundance measurements for 37 damped Lyα systems at z > 2.5 observed with the Echellette Spectrograph and Imager on the Keck II telescope. We measure the H I column
The UCSD/Keck Damped Lyα Abundance Database: A Decade of High-Resolution Spectroscopy
We publish the Keck/HIRES and Keck/ESI spectra that we have obtained during the first 10 years of Keck observatory operations. Our full sample includes 42 HIRES spectra and 39 ESI spectra along 65
The UCSD HIRES/Keck I Damped Lyα Abundance Database. II. The Implications
We present a comprehensive analysis of the damped Lyα (DLA) abundance database presented in the first paper of this series. This database provides a homogeneous set of abundance measurements for many
The UCSD HIRES/Keck I Damped Lyα Abundance Database. IV. Probing Galactic Enrichment Histories with Nitrogen
We present 14 N0 measurements from our High Resolution Echelle Spectrometer/Keck database of damped Lyα abundances. These data are combined with measurements from the recent and past literature to
The Most Metal-rich Damped Lyα Systems at z ≳ 1.5 I: The Data
We present HIRES observations for 31 damped Lyα systems, selected on the basis of their large metal column densities from previous lower-resolution data. The measured metal column densities for Fe,
A new comprehensive set of elemental abundances in DLAs II. Data analysis and chemical variation studies
Received; accepted Abstract. We present new, comprehensive sets of elemental abundances for seven damped Lyα systems (DLAs) in the redshift range zabs = 1.8− 2.5. These were derived from UVES/VLT
Metallicity Evolution of Damped Lyα Galaxies
We have reanalyzed the existing data on zinc abundances in damped Lyα (DLA) absorbers to investigate whether their mean metallicity evolves with time. Most models of cosmic chemical evolution predict
New detections of Mn, Ti and Mg in damped Lyα systems: Toward reconciling the dust/nucleosynthesis degeneracy
We have combined new high resolution UVES-VLT observations of a sample of four damped Ly systems (DLAs) at redshifts between zabs= 1:7 2:5 with the existing HIRES-Keck spectra to undertake a
Distinct abundance patterns in multiple damped ly alpha galaxies: evidence for truncated star formation?
Following our previous work on metal abundances of a double damped Ly system with a line-of-sight separation 2000 km s 1 (Ellison & Lopez 2001), we present VLT UVES abundances of 3 new systems
The ESO UVES Advanced Data Products Quasar Sample – IV. On the deficiency of argon in DLA systems
In this work, we study argon abundances in the interstellar medium of high-redshift galaxies (2.0 6 zabs 6 4.2) detected as Damped Lyα absorbers (DLA) in the spectra of background quasars. We use
