"sea level" refers to the National Geodetic Vertical Datum of 1929 (NGVD of I 929)--a geodetic datum derived <br />from a general adjustment of lhe first-order level nets of both the United States and Canada, formerly called Sea Level Datum of 1929. <br /> <br />For those who wish to convert dry-weight concentrations to wet-weight concentrations for biological <br />samples, the equation is: <br /> <br />wet weight = dry weight [l-(percent moisture/l 00)]. <br /> <br />CONTENTS IX <br />
