Scientific paper

We propose an ambitious spectroscopic investigation of the full spectrum of core collapse supernovae (CCSNe). By pursuing spectra of the most complete possible sample of Palomar Transient Factory (PTF) discovered CCSNe over the 2010B semester -- over 100 events in all -- we will carry out the first unbiased census of core collapse populations, confront the impact of stellar metallicity and progenitor mass loss on CCSN properties, and identify and characterize newly-discovered and rare subpopulations of CCSN in detail. Our proposed large NOAO program will build on the deep and unbiased nature of the PTF transient discovery process, with initial screening via near-complete ``first epoch'' spectroscopy of newly-discovered transients from collaboration facilities, to address fundamental questions about the nature and diversity of the core collapse phenomenon.
