Title: Wide, Deep KISS - Exploring the Properties of a Local Sample of Emission- Line Galaxies in the NWDFS

Abstract: We propose to carry out a spectroscopic study of the NOAO Wide Deep- Field Survey (NWDFS). Target galaxies come from our deep objective- prism survey for emission-line galaxies (KISS), a portion of which overlaps the Bootes field of the NWDFS. Our goal is to obtain spectra for all KISS ELG candidates (~170), which include objects to B=21. This will represent the first \bf complete sample of H(alpha)- selected KISS ELGs with follow-up spectra, allowing us to assess accurately the nature of the KISS sample constituents for the first time. It will also enable us to carry out a wide range of studies involving the star-formation and AGN activity in this deep, volume- limited sample of galaxies. The NWDFS field is the target of several deep surveys over a wide range of wavelengths, including the UV (GALEX), infrared (SIRTF), radio (FIRST/NVSS), and X-ray (Chandra). By combining our new spectra with these multi-wavelength data, we will be able to better calibrate the various star-formation rate indicators used to study star-formation in the distant universe. In addition to the spectroscopy of the KISS galaxies, will also observe roughly 850 non- ELGs to B ~ 19.5, constructing a deep magnitude-limited redshift survey for the NWDFS with an effective depth of z ~ 0.3 - 0.4. The full data set will be made available to the community immediately, to ensure the highest possible use of the data for a variety of projects involving the NWDFS.
