Exploring the Ocean

Science · Ocean Life · meta

Know that oceanographers and marine biologists study the ocean using submarines, remotely operated vehicles (ROVs), satellites, and diving, and that much of the ocean remains unexplored — we know more about the Moon's surface than the deep ocean floor

What mastery looks like

  • Name at least two tools scientists use to explore the ocean: submarines, ROVs, satellites
  • State that most of the deep ocean remains unexplored
  • Explain why ocean exploration is difficult: darkness, pressure, vastness

Check your understanding

Can Exploring the Ocean explain how scientists explore the deep ocean using robots and submarines, and why we've still only explored a small fraction of the ocean floor — less than we know about the Moon?
