Description
We describe deep, new, wide-field radio continuum observations of the Great Observatories Origins Deep Survey-North field. The resulting map has a synthesized beam size of ~1.7" and an rms noise level of ~3.9uJy/beam near its center and ~8uJy/beam at 15' from phase center. We have cataloged 1230 discrete radio emitters, within a 40'x40' region, above a 5{sigma} detection threshold of ~20uJy at the field center. New techniques, pioneered by Owen & Morrison, have enabled us to achieve a dynamic range of 6800:1 in a field that has significantly strong confusing sources. We compare the 1.4GHz (20cm) source counts with those from other published radio surveys. Our differential counts are nearly Euclidean below 100uJy with a median source diameter of ~1.2". This adds to the evidence presented by Owen & Morrison that the natural confusion limit may lie near 1uJy. If the Euclidean slope of the counts continues down to the natural confusion limit as an extrapolation of our logN-logS, this indicates that the cutoff must be fairly sharp below 1uJy else the cosmic microwave background temperature would increase above 2.7K at 1.4GHz.
