Data from indentation experiments conducted on natural iceberg ice at pond inlet in 1984 have been re-analyzed for three different sphericallyterminated indenter sizes for any given test it was found that the crushing specific energy of the ice shows little if any dependency on the volume of the displaced ice and tends towards a constant.
