We present deep SCUBA-2 450 μm imaging of the two GOODS fields, achieving a central rms of 1.14 mJy for the GOODS-N and 1.86 mJy for the GOODS-S. For each field, we give a catalog of >4σ detections (79 and 16 sources, respectively). We construct the 450 μm number counts, finding excellent agreement with others from the literature. We match the 450 μm sources to 20 cm data (both fields) and ALMA 870 μm data (GOODS-S) to gauge the accuracy of the 450 μm positions. We use the extensive redshift information available on the fields to test how well redshift can be estimated from simple flux ratios (450 μm /850 μm and 20 cm/850 μm), finding tight correlations. We provide a catalog of candidate high-redshift submillimeter galaxies. We look for evolution in dust temperature with redshift by fitting the spectral energy distributions of the sources, but we do not find any significant redshift evolution after accounting for the far-infrared luminosity. We do not find evidence for the 450 μm selection picking out warmer sources than an 850 μm selection. We find that a 450 μm-selected sample only adds low-redshift (z < 1.5) galaxies beyond an 850 μm sample.
