Exploring Oceanography and Mapping Techniques

Katie Croft Bell, an ocean explorer, discusses the use of satellites and deep-sea robotic vehicles to map and explore the seafloor. She highlights the capabilities of the exploration vessel Nautilus, equipped with advanced technology for data collection and sharing. The video also addresses the challenges of oceanography, emphasizing the difficulty of mapping the seafloor compared to Mars due to the vastness and depth of the ocean.
