  We have carried out a deep (21.5<R<23.9) systematic survey of galaxies
selected from SWIRE using GMOS to target X-ray sources, AGN and galaxies with
photometric redshifts greater than 1. We have obtained a total of 198
redshifts, of which 132 have secure redshifts in the range 0.12<z<1.21. This
sample, combined with the 111 redshifts targeted with WIYN in the same field
and the 1 square degree survey of ELAIS-N1 with ACIS-I, will allow us to
calibrate our photometric redshift techniques; characterise the star formation
history of the universe between 0.5<z<1.2 where galaxy formation activity
peaks; and explore the connection between AGN and star-formation activity.
