Secrets of the Sea

By Dr. Joseph M. Bishop

This 40-min lecture packed a lot of information in the allotted time. Here's a run-through of some facts I picked up:
  • Earth's oceans have an avg. depth of 2 miles
  • Ocean's are 95% unexplored
  • Earth's deepest point is The Mariana Trench @ 36,201 ft
  • Jellyfish have a kill rate 5x higher than sharks
  • A shark's nervous system can be disrupted by touching its nose
  • A pompeii worm can live in waters as hot as 175° F
  • 90% of all earthquakes happen along fault lines
  • DART (Deep Ocean Assessment & Reporting) is a tsunami detection system involving sensors in the ocean and deep-space satellites
  • Largest storm wave recorded was 150 ft high
  • OTEC (Ocean Thermal Energy Conversion) is a form of alternative energy that uses extreme temperature differences between deep and shallow waters
  • Turbines driven by tides are another form of alternative energy used in France
