  1. The Importance of Hydrothermal Vents

  2. Completely changed our view of life. • Chemosynthesis. • “Extreme’ life forms. • New ideas on the origin of life on Earth. • New ideas on life elsewhere.

  3. Improved out understanding of plate tectonics& Earth’s geology. • Mid-ocean ridges and sea-floor formation. • “Venting” of heat from within. • Origin of Earth’s huge ore deposits (iron, zinc, copper, lead) in the crust.

  4. New understand of the chemistry of the sea. • Constantly recycling sea water. • Why it is full of salt and other minerals. • Removes some elements while adding others. • Keeps the chemistry of the sea balanced.

  5. Technology & Engineering improvements. • ALVIN!! • Battery life. • Robotics. • Photography. • Sea-floor mapping.
