[USMA:37216] Clive Cussler adventure novels

[Norman & Nancy Werling]

Several years ago he wrote "Aztec Gold" (I think that was the title) in which he used all metric terms.  Since then he has reverted to non-metric.  I often wondered if he caught flak that caused to revert back.   I just began reading "White Death" published in 2003 in which his new hero used the term "fathometer."  Jim Frysinger may be the most likely to know if there has ever been and if there continues to be such an instrument to measure depth.   Norm
