“…So the squashing of the earth by the glaciers of the Quarternary Ice Age accounts for between 13 per cent and 40 per cent of the present-day nonhydrostatic part of J 2 , with a preferred value of 22 per cent. Wang (1966) had suggested that glaciation might account for all of ^J 2 , but McKenzie (1966), Kaula (1967), and O'Conn ell (1971) indicated that glaciation accounts for an amount closer to the percentages given here. (For further discussion of AJ 2) see Goldreich and Toomre, 1969).…”

“…Wang (1966) thought the excess flattening might be due to heavy glaciation at the poles, which would squeeze out a bulge due to the weight of the ice. This view was 13 criticized by McKenzie (1966), Kaula (1967), and O'Connell (1971); they indicated the ice caps would have to be unacceptably large to produce the extra flattening. Kahn and O'Keefe (1974), however, showed that glaciation in Antarctica probably produced the gravity field's large third harmonic, giving the earth its "pear shape. "…”

“…Since the earth's gravitational potential energy has received . attention (and spherical harmonic treatments) in the past, particularly from MacDonald (1966), McKenzie (1966), and Kaula (1967), it should prove worthwhile to derive a general equation for the energy from the viewpoint of spherical harmonics.…”

“…It is a degree variance (or its square root, degree-RMS) that has been often used to quantify the powers of signal and error in the gravity field estimates at various spatial wavelengths (Kaula 1967). In addition to admittance and correlation functions, it is useful to analyze and compare the global topography and (static) gravity to understand physical implications of their spatial variations for Earth and other planets' geodynamics (e.g., Kaula 1967;Wieczorek 2007).…”
