We present large continuum maps (13' x 18') continuum maps at 850 mu m and 450 mu m of the active star formation region NGC 1333, obtained with the bolometer array camera SCUBA on JCMT, Mauna Kea, Hawaii. These maps are sensitive enough to detect dust surrounding any YSO and protostar to a mass limit of less than or equal to 0.01 MSun, and also sensitive enough to probe the the dense molecular gas surrounding these YSOs and protostars. We find more than 30 discrete sources, some of which are extended and may contain multiple condensations. We compare the continuum survey with the CO J=3-2 (Knee & Sandell, 1999), which shows at least eight different outflows in the main NGC 1333 cloud, many of which are spatially overlapping. Most of the outflows are driven by protostellar or deeply embedded young PMS stars, all of which show up as strong continuum sources in our SCUBA survey. The continuum maps show dust ridges and shells, which are caused by powerful outflows that we see in our CO J=3-2 maps. In two cases we indentify proto--stellar sources, which have been triggered by powerful bowshocks in the outflows. Almost all of the strong sources, IRAS 4 A,B, IRAS 2, and SSV 13 B have been identified as Class 0 sources, but this survey suggests that many of the fainter sources are likely to be even lower mass Class 0 objects. Very few of the submillimeter sources have optical or near-IR counterparts. Knee, L.B.G. & Sandell, G. 1999, A&A, being revised
