The Boston University-Five College Radio Astronomy Observatory Galactic Ring Survey is a new survey of Galactic 13CO(1--0) emission. The survey used the SEQUOIA array on the Five College Radio Astronomy Observatory 14 m telescope to cover a longitude range of l = 18 deg -- 55.7 deg and a latitude range of |b| < 1 deg, a total of 75.4 square degrees. We achieved an angular sampling of 22 arcsec, better than half of the telescope's 46 arcsec angular resolution. The survey's velocity coverage is -5 to 135 km s-1 for Galactic longitudes l < 40 deg and -5 to 85 km s-1 for Galactic longitudes l > 40 deg. At the velocity resolution of 0.21 km s-1, the typical rms sensitivity is sigma(TA*) ˜ 0.13 K. The survey comprises a total of 1,993,522 spectra. We present the integrated intensity image (zeroth moment map), channel maps, and position-velocity diagram. The Galactic Ring Survey data are available to the community at www.bu.edu/galacticring or in DVD form by request.
