Wilson (1964); Wilson (1966); Wilson (1969); Wilson's starting - point was the suggestion that the center of Antarctica was at the pressure melting point, see Robin (1962), p. 141, who adds that «one would not expect the ice to surge over a large part of Antarctica at one time»; the role of
frictional heat in ice - sheet instability was pointed out back in 1961 (in partial support of Ewing - Donn theory), drawing
on earlier work by G. Bodvarsson, by Weertman (1961).
