  We report the results of an extensive spectroscopic survey of galaxies in the
roughly 160 square arcminute ACS-GOODS region surrounding the HDF-N. We have
identified 787 galaxies or stars with z'<24, R<24.5, or B<25 lying in the
region. The spectra were obtained with either the DEIMOS or LRIS spectrographs
on the Keck 10m telescopes. The results are compared with photometric redshift
estimates and with redshifts from the literature, as well as with the redshifts
of a parallel effort led by a group at Keck. Our sample, when combined with the
literature data, provides identifications for 1180 sources.
  We use our results to determine the redshift distributions with magnitude, to
analyze the rest-frame color distributions with redshift and spectral type, and
to investigate the dependence of the X-ray galaxy properties on the local
galaxy density in the redshift interval z=0-1.5. We find the rather surprising
result that the galaxy X-ray properties are not strongly dependent on the local
galaxy density for galaxies in the same luminosity range.
