  We present a pilot study of 16 micron imaging within the GOODS northern
field. Observations were obtained using the PeakUp imaging capability of the
Spitzer IRS. We survey 35 square arcminutes to an average 3 sigma depth of
0.075 mJy and detect 149 sources. The survey partially overlaps the area imaged
at 15 microns by ISO, and we demonstrate that our photometry and galaxy-number
counts are consistent with their measurements. We infer the total infrared
luminosity of 16 micron detections using a comparison to local templates and
find a wide range of L_IR} from ~10^9 to 10^{12} L_sun. Approximately one fifth
of the detected sources have counterparts in the Chandra 2 Msec catalog, and we
show that the hard band (2-8 keV) detected sources are likely to have strong
AGN contributions to the X-ray flux. The ultradeep sensitivity of Chandra
implies some X-ray detections may be purely starbursting objects. We examine
the 16 to 24 micron flux ratio and conclude that it shows evidence for the
detection of redshifted PAH emission at z~0.5 and z>0.8.
