"...and that a sounding taken just minutes before the accident did not correlate with the charts that were in use at the time, which should have prompted him to be more cautious."

This is what did him in right here. The proper procedure for going deep goes like this:

OOD: "Quartermaster, take a sounding." QMOW: "Sounding is 1800 fathoms, matches chart." OOD: "Very well Quartermaster. All stations, Conn. Going deep."

Any other response from the QMOW means you do not go deep until the discrepancy between charted and actual depth is resolved.

Any other response from the QMOW means you do not go deep until the discrepancy between charted and actual depth is resolved.

Repeating this important piece of information for those who keep asking "but what about the discrepancy with the charts" or "why weren't they using sonar" or any of the other questions.

This is the failure of the Captain to pay attention to the information that the sonar ping gave him.
