Greenland's Rapid Postglacial Emergence: A Result of Ice-Water Gravitational Attraction: Comment and Reply.

摘要

This note comments upon a paper published in 'Geology', v.4 no.5 1976, in which J. A. Clark presented a simple method by which to calculate the change in sea level caused by the gravitational attraction of an ice cap. In the same paper he also presented some results of a more complex numerical solution of the problem, and the two calculations are in a disagreement. Tapscott points out that, in fact, Clark's more powerful solution is correct. His simple calculation contains an error. The present note points out the reason for the error lest doubt be cast on his numerical method and the many interesting consequences of his thesis.
