We have used GMOS on Gemini-N, LRIS on Keck I and COSMIC on the Palomar 200'' telescopes to obtain spectroscopy of the faint (r' ~22-25) galaxy population in the Lockman Deep Field of the Spitzer Wide-area InfraRed Extragalactic Legacy Survey. Most of the galaxies selected are radio-detected in the SWIRE Deep VLA Survey at 20cm (Owen et al. 2005). The redshift distribution, 0.4 < z < 3.5, has a median, z ~0.9, consistent with pre-launch models. Three objects with z > 2 are all broad-line AGN.

The spectroscopic sample will be compared with photometric redshift estimates which will be required to characterize the majority of the 2 million galaxies expected in the SWIRE Survey. Optical-IR SED templates are being employed to characterize the galaxy populations. These characterizations will be compared with galaxy spectroscopic characteristics.

We wish to acknowledge the substantial contributions of the Gemini, Keck and Palomar Observatories staffs. This work has been supported by NASA through the Spitzer Science Center.
