Over 1000hr of observation were dedicated to this project exploring CMB anisotropy, on scales between 1' and 2' in eighteen 6.6' FWHM fields. In the analysis of the CMB power spectrum, the visibility data are divided into two bins, corresponding to different angular scales. Description: The BIMA anisotropy survey consists of 18 fields that had not been previously observed for SZ galaxy clusters or CMB anisotropy at arcminute angular scales. Each field was observed with the BIMA array at a frequency of 28.5GHz and the VLA at a frequency of 4.8GHz. Analysis of 10 fields observed with the BIMA array during the summers of 1998, 2000, and 2001 revealed evidence for a detection of power in excess of the instrumental noise. A description of the analysis and results for the first 10 fields in the survey can be found in Dawson et al. (2002ApJ...581...86D). Eight new fields were added to the survey in the summer of 2002.
