Title: A GMOS spectroscopy survey of Herschel sources in the CANDELS UDS field

Abstract: The combination of deep near-IR and optical HST imaging, deep Herschel photometry and vast amounts of ancillary data available highlight the CANDELS fields as the best photometrically observed areas in the sky. However, relative to the GOODS fields, the CANDELS-UDS lacks spectroscopic coverage, in particular of the Herschel-detected galaxies. By contrast, each of the GOODS fields (each 0.044 deg^2) has 3000-4000 published redshifts. We propose to rectify this with a GEMINI/GMOS spectroscopic survey on ~300 Herschel-selected galaxies in the CANDELS UDS field and increase the pool of galaxies with CANDELS HST+Herschel imaging that are observable with ALMA by a factor of 2. This proposal complements our 2014A (band 1) program of spectroscopy for Herschel sources in the CANDELS COSMOS field. Redshifts and spectral measurements will enhance the legacy value of the deepest HST + Herschel data, and will also allow us to study environmental effects as well as to address fundamental questions about what controls star formation in the \it majority of star-forming galaxies, including occasional boosting, quenching, and effects on the ISM.
