We present the complete submillimeter data for the Canada-UK Deep Submillimeter Survey (CUDSS) 3-hour field. The obeservations were taken with the Submillimeter Common-User Bolometer Array (SCUBA) on the James Clerk Maxwell Telescope on Mauna Kea. The 3-hour field is one of two main fields in our survey and covers 60 square arcminutes to a 3-sigma depth of 3 mJy. In this field we have detected 27 sources above 3-sigma and 15 above 3. 5-sigma. We assume the source counts follow the form N (S) \ S^-\ and measure \ = 3. 3^+1. 4-₁. ₀. This is in good agreement with previous studies and further supports our claim (Eales et al. , 2000) that SCUBA sources brighter than 3 mJy produce ~20% of the 850\m background energy. Using preliminary ISO 15 \m maps and VLA 1. 4 GHz data we have identified counterparts for six objects and have marginal detections at 450\m for two additional sources. With this information we estimate a median redshift for the sample of 2. 0\0. 5, with \10% lying at z 3 mJy sources using the source catalogues from the CUDSS two main fields, the 3-hour and 14-hour fields, and find a marginal detection of clustering, primarily from the 14-hour field, of \ (\) =4. 4\2. 9 \^-0. 8. This is consistent with clustering at least as strong as that seen for the Lyman-break galaxy population and the Extremely Red Objects. Since SCUBA sources are selected over a broader range in redshifts than these two populations the strength of the true spatial clustering is expected to be correspondingly stronger.
