  <dc:description>&lt;p&gt;Five radiocarbon ages, all determined by accelerator mass spectrometry, have been obtained for two pre-bomb bivalves from Lake Michigan and one from Lake Huron. After correcting those ages for the fractionation of&lt;span class="a-plus-plus"&gt;14&lt;/span&gt;C in calcite and for the radioactively inert CO&lt;span class="a-plus-plus"&gt;2&lt;/span&gt;&amp;nbsp;in the atmosphere, we find residual ages, caused by the hard water effect, of about 250 years for Lake Michigan and 440 years for Lake Huron.&lt;/p&gt;</dc:description>
