  <dc:description>&lt;p&gt;&lt;span&gt;Recent studies on the changes in composition of interstitial water during its separation from sediments&lt;/span&gt;&lt;sup&gt;1-3&lt;/sup&gt;&lt;span&gt;&amp;nbsp;prompted us to evaluate the effect of squeezing on the concentration of ferrous iron within the interstitial water. Sediment samples were taken in northern Chesapeake Bay (38°56′ N and 76°25′ W) with a Benthos gravity corer. Layers of sediment were immediately extruded from the plastic coring tube and loaded into nylon squeezer barrels. The interstitial water was squeezed from the sediment through a 0.22 μm Millipore filter by the pressure of nitrogen acting against a rubber diaphragm&lt;/span&gt;&lt;sup&gt;4&lt;/sup&gt;&lt;span&gt;. The water drained directly into a calibrated test tube containing a solution of o-phenanthroline, buffered at pH 3.6, and the iron content was determined colorimetrically&lt;/span&gt;&lt;sup&gt;5&lt;/sup&gt;&lt;span&gt;. © 1974 Nature Publishing Group.&lt;/span&gt;&lt;/p&gt;</dc:description>
