Using 2MASS data, we are systematically searching for the coolest sub-stellar objects known - ``T'' dwarfs, or methane brown dwarfs. To date, follow-up investigations of 2MASS candidates have identified nine T dwarfs, four from our first CTIO run in 1999 July, bringing the currently known T dwarf population to twelve. Our program is focused on producing a spatially complete, statistically significant, spectroscopic sample in order to investigate the observable properties of these cool brown dwarfs. We are also working toward a T spectral sequence, which necessitates measurements of molecular band strengths, atomic lines, and other temperature-dependent spectral signatures, for which OSIRIS in cross-dispersed mode is ideally suited. We thus propose to continue our southern hemisphere investigation of T dwarfs at CTIO. We will use the 1.5m CIRIM to image our candidate sources (in order to exclude contaminant asteroids), and the 4m OSIRIS in cross-dispersed mode to acquire broad spectral data for T dwarf investigation and classification.
