The establishment of a calibration standard for gravimeters in Eastern Canada and the United States

  • M. J. S. Innes


A program of gravimeter measurements for the establishment of a suitable gravity standard in eastern Canada and United States is described. It is shown that the consistency of nine independent measurements of the gravity differences between stations forming a north-south line from Ottawa to Washington is highly satisfactory and that this line is suitable for calibration purposes. The gravity differences depend fundamentally upon a gravimeter calibration made against values of gravity at Cambridge pendulum stations in Canada.
