Science Fridays!

 I didn't feel right keeping the "Fun" given the reason for the topic.  Surely you've heard about the Titan submersible and its passengers.

The Coast Guard located a debris field on the ocean floor and the Navy confirmed they detected sounds consistent with implosion just an hour and a half into the dive.

The water pressure at the site of the Titanic wreck is roughly 6,000 psi.

For every 33 feet you go down, the pressure increases by one atmosphere, (the weight of the earth's atmosphere at sea level).  At sea level, we are met with about 14.7 psi.

Director James Cameron commented on the importance of hull composition when developing these subs, stating the carbon-fiber composite OceanGate used has "no strength in compression."
