We present Spitzer 16 micron imaging of the Great Observatories Origins DeepSurvey (GOODS) fields. We survey 150 square arcminutes in each of the two GOODSfields (North and South), to an average 3 sigma depth of 40 and 65 micro-Jyrespectively. We detect about 1300 sources in both fields combined. We validatethe photometry using the 3-24 micron spectral energy distribution of stars inthe fields compared to Spitzer spectroscopic templates. Comparison with ISOCAMand AKARI observations in the same fields show reasonable agreement, though theuncertainties are large. We provide a catalog of photometry, with sources crosscorrelated with available Spitzer, Chandra, and HST data. Galaxy number countsshow good agreement with previous results from ISOCAM and AKARI, with improveduncertainties. We examine the 16 to 24 micron flux ratio and find that for mostsources it lies within the expected locus for starbursts and infrared luminousgalaxies. A color cut of S_{16}/S_{24}>1.4 selects mostly sources which lie at1.1<z<1.6, where the 24 micron passband contains both the redshifted 9.7 micronsilicate absorption and the minimum between PAH emission peaks. We measure theintegrated galaxy light of 16 micron sources, and find a lower limit on thegalaxy contribution to the extragalactic background light at this wavelength tobe 2.2\pm 0.2$ nW m^{-2} sr^{-1}.
