is the statement:
</p>
<dl><dd>"A large portion change in d18Oc records is thought to result of the sequestration of isotopically light oxygen (16O) in large continental ice sheets, resulting in ocean water that has a larger proportion of 18O."</dd></dl>
Thus reduction of oxygen 18 (which is upward on the graph) indicates warmer conditions and higher sealevel.
